00:00All over the world, species clash in nature's savage battle of survival.
00:14On land, under the sea, and in the air, all are locked in deadly conflict.
00:25Animals fight tooth and claw to win food, territory, and rights to the bloodline.
00:35From the mountains of Asia to the wilds of Canada, there are no rules.
00:42This is Animal Fight Club.
00:55Our first contender was born for Animal Fight Club, with unadulterated aggression in his genes.
01:05Literally, the Toro Bravo, or Spanish fighting bull.
01:09For generations, only the strongest bulls have bred.
01:20This is the result.
01:24He's packed full of over half a ton of powerful muscle, and sees red at the flick of a switch.
01:31He can charge at 40 miles an hour.
01:36And his horns are not just for showing off.
01:39They're also deadly goring weapon raider.
01:46These bulls are the fiery linebackers of the cattle field.
01:50This black five-year-old is the undefeated champion of his herd, just like his ancestors.
01:58This gives him exclusive breeding rights to any female.
02:02So he won't tolerate any challenge to his authority.
02:06But there's a new bull in town, with an equally deadly pedigree.
02:10He will gore the boss to death, if that's what it takes to gain power over the herd.
02:18The boss rises to the challenge.
02:21It's game on!
02:27The boss forces the newcomer down to the grass.
02:31Now he has solid footing.
02:34The boss's front legs anchor him.
02:45He locks the newcomer in a heated head wrestle.
02:56Using their curved horns like a pitchfork, they can lift over half a ton.
03:01More than enough to twist their opponent off balance.
03:04More than enough.
03:06More than enough.
03:10Fighting bulls have a mega neck muscle between their shoulders called the Murillo.
03:15It's twice as big as regular cattle.
03:18And gives the boss his distinctive profile and strength.
03:21With these neck muscles, he can tip over a car.
03:28The collisions are brutal.
03:30Enough to put cracks into solid brick walls.
03:35Their horns can take half ton loads during combat, without breaking.
03:40They're solid keratin at the tip for goring, but hollow further down, so they're lighter and easier to maneuver.
03:47A keratin coating toughens the entire horn, transferring any load down into the skull or the bone core.
03:57The boss takes advantage of the terrain.
04:00Using brute strength, he forces the newcomer to splay his legs.
04:11If he can, the boss will use the tips of his horns to rip through the newcomer's flesh.
04:17But it's a headlock.
04:18But it's a headlock.
04:24Suddenly, an outsider bull sees his chance.
04:25A hit to the boss's blind spot.
04:26A hit to the boss's blind spot.
04:27With eyes on the side of his head, the boss has incredible panic.
04:28A hit to the boss's blind spot.
04:29With eyes on the side of his head, the boss has incredible panic.
04:30A hit to the boss's blind spot.
04:31It's a headlock.
04:32It's a headlock.
04:33It's a headlock.
04:34It's a headlock.
04:35It's a headlock.
04:36It's a headlock.
04:37It's a headlock.
04:38It's a headlock.
04:39It's a headlock.
04:40It's a headlock.
04:41It's a headlock.
04:42It's a headlock.
04:43It's a headlock.
04:44It's a headlock.
04:45It's a headlock.
04:46It's a headlock.
04:47It's a headlock.
04:48It's a headlock.
04:49It's a headlock.
04:50It's a headlock.
04:51It's a headlock.
04:52It's a headlock.
04:53It's a headlock.
04:54It's a headlock.
04:55It's a headlock.
04:56It's a headlock.
04:57It's a headlock.
04:58330 degrees, but can't see directly behind him. It's a coup. The Outsider pushes the boss out of the ring.
05:09Now it's newcomer versus Outsider. With the Outsider's fresh energy and superior size,
05:16it's only a matter of seconds. The power reshuffle is over. There's a new boss on this land.
05:23And he's got plenty more fighting in store if anyone disagrees.
05:33Disagreements become even deadlier when two of the world's ultimate fighters duke it out in one of the planet's most extreme places.
05:42The Canadian wilderness, deep snow, and freezing temperatures.
05:47A death trap for most, but not for the elusive Canadian Lynx.
05:51This wildcat has all the mountaineering equipment to survive this brutal environment.
05:59Thick fur.
06:01Long legs with big fluffy paws that work like snowshoes, so that he can move quickly through the deep powder.
06:09Perfect for hunting hares, the main part of his diet.
06:13Tufts of hair at the tip of his ears act as antennas to enhance his hearing.
06:20He can spot a mouse up to 250 feet away.
06:26To make sure he has enough to eat, he lives alone in his 115 square mile territory.
06:33And he protects it, viciously.
06:46As night falls, he gets ready to hunt.
06:49He spots an intruder.
06:53One of North America's other native wildcats.
06:58The bobcat.
07:00An in-your-face, all-out predator with a ferocious appetite.
07:05He's not as well adapted as the Lynx for this snowy terrain.
07:08But he makes up for it in determination and aggression.
07:13He can stalk his prey for hours.
07:16And within seconds, he leaps over 10 feet to deliver his death blow.
07:24With food scarce, these two are destined for a face-off.
07:29The bobcat is more aggressive by nature.
07:45And he's driven by hunger.
07:48But Lynx have a crucial advantage.
07:51They're taller and heavier.
07:55On the bobcat's cue, the claws are out.
07:59The bobcat slams the Lynx to the ground.
08:10He could disembowel him with one swipe.
08:14But he can't penetrate the Lynx's thick fur.
08:22Belly up looks vulnerable.
08:25But it's strategy.
08:26To kill, the bobcat bites the spine to break the neck.
08:32But he can't quite reach from here.
08:35The Lynx guards his neck and pushes backward against the snow.
08:39A leap, thanks to his large, snowshoe-like paws.
08:45The Lynx retaliates with a heavyweight punch.
08:48The bobcat takes a mean right hook.
09:00But then his determination kicks in.
09:03He aims all four sets of claws at the Lynx's body.
09:07A longer reach means the Lynx can punch the bobcat while avoiding his claws.
09:16He slams the bobcat down.
09:19But it's no knockout.
09:20The relentless bobcat delivers a massive blow.
09:35The Lynx concedes.
09:40The Lynx concedes.
09:41The bobcats may be smaller, but size is no match for unbridled ferocity.
09:46The Lynx needs to make himself scarce.
09:49The bobcat rubs his scent in the snow, marking his territory.
09:54A clear sign to any new trespassers that this is his land now.
10:00One-on-one combat is nothing compared to mob warfare, when a high death count is inevitable.
10:09The majestic mountains of Japan, East Asia.
10:14Home to the largest hornet in the world.
10:17A Japanese giant hornet.
10:20This adult female is aggressive and fearless.
10:24And a colossal two inches long.
10:26Her body is an artillery of deadly weapons.
10:34She's got a quarter-inch stinger that pumps out venom that can dissolve human tissue.
10:42Her scissor-like jaws are half the size of her head.
10:46The equivalent of a human having five-inch teeth.
10:49Supported by enormous cheek muscles, they can rip her enemies to shreds.
10:54And, she's a team player.
10:58She works with a swarm of 30 fellow hornets.
11:01When these voracious predators strike, it usually results in a massacre.
11:08But even the most prolific killers meet their match.
11:12Eventually.
11:12This nest is home to 100 giant Japanese hornets.
11:19The offspring of one queen.
11:21The entire future of the nest depends on the survival of these monsters.
11:27The hornets' royal babies.
11:30Just a few weeks old, these insatiable eating machines are already close to the size of an adult.
11:37Their favorite meal?
11:39Honeybees.
11:40To keep up with their enormous demand, adult hornets launch daily raids on nearby hives.
11:51They can decapitate a bee with just one bite of their powerful jaws.
11:56At a devastating rate of 40 honeybees a minute.
12:04Just 30 giant hornets can slaughter a hive of 30,000 honeybees in under three hours.
12:11The raiding party scout hornet is on a mission to find more bees.
12:26Flying at 25 miles per hour, this scout can cover 60 miles a day.
12:31This honeybee colony is right on her flight path.
12:38They're about to become royal baby food.
12:42The guard honeybees raise the alarm.
12:45Within a matter of seconds, it's red alert.
12:48There are 30,000 honeybees in this colony.
12:52The hornets could wipe them out in just a few hours.
12:56Outside, the scout hornet leaves a scent mark so that she can return with reinforcements.
13:01But she can't resist a sneaky look inside.
13:06The bees are ready for her.
13:08Five times lighter, a Japanese honeybee is no match for the giant Japanese hornet.
13:17But working together, Japanese honeybees create a unique weapon unequaled in the animal kingdom.
13:27And they're about to unleash it.
13:32They start to flap their wings.
13:38The hornet doesn't take any notice.
13:41She can decapitate these bees one bite at a time.
13:47It's an ambush.
13:49500 bees pile onto her, all relentlessly flapping their wings.
13:54This creates tremendous heat.
13:57They are unstoppable.
14:00The temperature is rising fast, and there's no escape.
14:08These thermal images show the hornet trapped inside the ball of honeybees.
14:14It's 100 degrees and rising.
14:17The bees are so tightly packed that the heat has nowhere to go.
14:21The hornet is in a bee fireball.
14:25But this is a dangerous game.
14:27The bees could overheat, too.
14:28The hornet will die at 116 degrees.
14:33The bees at 122 degrees.
14:36That's a precious six-degree margin that gives them the advantage.
14:42Inside the bee ball, the temperature hits fatal.
14:46Thanks to their extraordinary teamwork, in just 10 minutes, the Japanese honeybees roast the hornet alive.
15:00But this mob of honeybees leaves nothing to chance.
15:04They remove the hornet's scent so that none of her family can come after her.
15:08Every trace of the monster predator is wiped from the face of the earth.
15:12Cunning strategy can be decisive over life and death.
15:20But sometimes, it just takes brute force and epic violence to seal the deal.
15:27South Africa, in the dry season.
15:30These chakma baboons live in close-knit troops of around 50 members,
15:35where the elders keep a watchful eye on their young.
15:37A crucial job, when this is the only pool to drink from in the whole neighborhood.
15:46The Nile crocodile is the most ferocious crocodile in Africa.
15:52Males can grow up to 19 feet long, and weigh up to 2,000 pounds.
15:58They are the second largest of all living reptiles.
16:02A brutal killing machine.
16:03They can eat half their own weight in one sitting.
16:08And there are an incredible 60 of them here, fiercely competing for water and food.
16:18And food comes in the form of thirsty baboons.
16:22The more patient family members have a cunning solution.
16:25They dig pits at the pool's edge, and drink water from the bottom.
16:30But this 10-year-old nursing mother needs water so desperately, she's beyond caution.
16:36She'll pay for this risk with the fight of her life.
16:42This nursing mother is so thirsty, she's drinking directly from a pool infested with 60 starving crocs.
16:49This hungry female teenager has her eyes on the reckless baboon.
16:56The mother keeps drinking.
17:02This is a huge mistake.
17:04The croc grabs both mother and baby.
17:25The Nile crocodile has one of the most powerful bites on Earth.
17:29The croc's sharp conical teeth are designed to sink into her catch's flesh, allowing for a grip that is almost impossible to loosen.
17:41Her next move, drown her victims.
17:45But clamping down on both mother and baby proves tricky.
17:51The croc adjusts her bite, and with impeccable timing, mom escapes.
17:55But her broken arm is a death sentence.
18:02Her family raises the alarm.
18:05In the confusion, she dropped her baby.
18:07He's alive, but only just.
18:10The baboons must distract the croc before she gets the baby.
18:15First, the baby's uncle taunts the croc with his body.
18:20He swings out of the way like a matador.
18:22And uses his most lethal weapon, sharp canine teeth.
18:30His canines are two inches long, almost as long as a lion's.
18:35He aims right for her back.
18:37The skin on the crocodile's back is thickened by bony plates.
18:41An armor so tough, a knife would struggle to pierce it.
18:45She escapes his bite, and snatches the baby.
18:49But now the other crocodiles want to steal her snack.
18:53So she leaves the water.
18:55This time, she has dad to contend with.
18:58At 70 pounds, he's a worthy adversary.
19:01He pummels her again and again, chasing and grabbing the croc to try to make her drop his baby.
19:15The croc is beat.
19:17She heads back to the water, without the baby.
19:21The baboon's teamwork crushes the super predator.
19:25But dad's heroic rescue is too late.
19:29The baboon's troop have lost a member.
19:31But their family spirit is unscathed.
19:34A mouthful of razor-sharp teeth looks intimidating.
19:46But just one mega-sharp, super-strong weapon can be just as savage.
19:52The grey heron is one of the largest airborne contenders on Animal Fight Club.
19:57Standing 40 inches tall with a 70-inch wingspan,
20:01these birds are the unmistakable kings of the sky.
20:04Their long necks and dagger-like bills equip them for the most brutal battles.
20:17This four-year-old male stakes out his feeding territory on the banks of a river.
20:24Herons have a characteristic S-shaped kink in their necks,
20:28the result of a special elongated bone that anchors extra muscles.
20:34He can coil his head back like a loaded spring
20:37and strike at prey in under a second.
20:44He senses danger.
20:45A bigger bird looms on the other side of the bank.
20:50He's a year older, and he wants in on this hunting ground.
20:56He swoops down for an incoming challenge.
20:59His huge wingspan gives him the advantage.
21:02If the younger gun wants to hunt in these waters, he'll need his A-game.
21:15The bigger male is the first to rise up to mount the attack.
21:18Older and stronger, he lifts higher off the ground to bear down on the younger male,
21:27boosted by the force of gravity.
21:30His scissor-like beak secures his dominance.
21:34The six-inch weapon is made of bone layered up with keratin,
21:38a super-tough harpoon that can stab through his opponent.
21:42The two birds dance in a vicious ballet.
21:54Locked in this lethal embrace,
21:57there's a chance their long necks could break.
22:00They have incredible forward-backward flexibility,
22:03but very little from side to side.
22:05But it's a risk worth taking.
22:08The older male pushes down on his opponent.
22:12With his superior weight,
22:13he finally submerges the younger bird under the water.
22:17This deliberate tactic makes the youth wetter and heavier.
22:24But the smaller heron finds strength,
22:27not to fight,
22:29but to escape.
22:31He's not tough enough to defend this hunting ground.
22:39He flies off
22:41before the old heron strikes again.
22:44He needs to find somewhere else to feed.
22:49Age and experience win the day.
22:51But sometimes you're born to win.
23:05Our next combatant uses chemical warfare.
23:09Found all over America,
23:11striped skunks can unload a supreme liquid stink bomb so powerful,
23:15it can give even large predators chemical burns.
23:18This mountain lion is 15 times bigger than the skunk,
23:23but even he walks away from this stinky, striped soldier.
23:27But a stink bomb isn't the only weapon at their disposal.
23:31When skunk takes on skunk,
23:34teeth and claws make for a bloody battle.
23:37It's late fall in this American woodland.
23:44This two-year-old male is bulked up for winter.
23:47And like all skunks,
23:48he'll go into a version of hibernation.
23:51When spring comes,
23:52he'll have lost almost half his body weight.
23:55He must find a robust winter den to keep him safe.
24:00Without one,
24:01he may only have a 50-50 chance of survival.
24:04He strikes gold.
24:09This den is the difference between life and death.
24:16But another skunk has his eye on this vital piece of real estate.
24:22It's heading for a full-on skunk smackdown.
24:25The intruder aims his teeth
24:31right for the loose skin of the home skunk's neck.
24:36Their canine teeth can bite a human finger to the bone.
24:40This is the power move.
24:45Pinned down,
24:46the home skunk can't fight back.
24:49Usually a push and a squawk would settle neighborly disputes.
24:53But this is a desperate fight for life.
24:56The intruder flips the home skunk onto his back,
25:00giving him easy access to his vulnerable throat.
25:03But the home skunk makes his power move.
25:09His bite is a brutal blow.
25:11Blood stains the intruder's fur.
25:20Both skunks try to flip each other,
25:23using their well-muscled legs and large feet as leverage.
25:27The goal is access to the soft underbelly and vital organs.
25:32However tempting,
25:33neither skunk releases their liquid stink bomb.
25:36It affects them too,
25:39but with a limited supply of ammunition,
25:41they only pull the trigger as a last resort.
25:49Finally free of the home skunk's bite,
25:52the intruder pushes his rear against him,
25:54forcing the home skunk backwards.
25:59He turns to bite.
26:06But soon flips back again,
26:11putting some well-needed distance between his neck
26:13and the home skunk's teeth.
26:16The home skunk has had enough.
26:18This is his winter house.
26:20The intruder squawks to save face.
26:24But he's lost.
26:28The home skunk will survive winter,
26:31but the intruder might not.
26:32The battle for survival is a year-round struggle,
26:41with death only ever moments away.
26:46With more venomous creatures than anywhere else in America,
26:51the Sonoran Desert is no place for the timid.
26:55As night falls,
26:57one of its most terrifying residents begins his prowl.
27:00This giant desert centipede is almost five years old.
27:06At seven inches long,
27:08he's one of the largest centipedes in the world.
27:11And tonight, he's got a giant appetite.
27:15To kill his dinner,
27:16he uses weaponry hidden beneath his head.
27:19He can paralyze and kill using his two huge venomous claws.
27:24He secretes a venom more potent than most scorpions.
27:30It's a cocktail of dozens of toxins.
27:33A dose can kill an ordinary mouse in a matter of seconds.
27:38There's even an account of one killing a human.
27:42This centipede's stores of venom are full.
27:45He's got enough to take down 12 mice.
27:47He's just got to find one.
27:54She might not look like a warrior,
27:56but looks can be deceiving.
27:59She's a grasshopper mouse,
28:01and she's heading out to find her own dinner.
28:05Her shrill howl can be heard for over 300 feet.
28:08In the Sonoran Desert,
28:12she knows you either kill or get killed.
28:18She spots the centipede.
28:20He's already got one mouse in his claws,
28:23and he wants her next.
28:25It's a fight to the death.
28:33The giant centipede throws his back legs at the mouse.
28:37He saves his venom for when he can get a strong grip.
28:43Each of the centipede's 42 legs has a claw on the end
28:46to restrain its prey.
28:48They're so sharp,
28:49they can cut right through the mouse's skin.
28:52His end legs are longer
28:53and can curl to get a good grip on his opponent,
28:56while the rest close on her like a cage.
29:01Covered in needle-like legs,
29:03the mouse gets a battering.
29:07The centipede's tail looks very similar to his head,
29:10where his venomous claws are.
29:20This is for his killer move.
29:22As the mouse tries to bite him,
29:25he twists in on himself
29:26to inject his venom.
29:28But he misses.
29:31Like a kung fu master,
29:33the mouse escapes
29:34with a 180-degree jump.
29:39She finally reveals her game.
29:43Unlike any other mouse in North America,
29:45she eats meat,
29:47and she has a taste for centipede.
29:50Her strategy?
29:51Death by a thousand cuts.
29:53One bite,
29:55one kung fu escape jump.
29:57Again,
29:58and again.
30:00A tough layer called the cuticle
30:02covers the centipede's entire body.
30:05It acts as a protective armor
30:06against other insect bites.
30:08But the mouse's teeth are like knives
30:10that pierce right through it.
30:12With each bite,
30:13she can damage the centipede's central nervous system,
30:16and each leg below the point of penetration
30:18could be paralyzed.
30:19But the centipede won't give up.
30:23He narrowly misses her eyes.
30:27They are her most valuable hunting tools,
30:29so she protects them
30:31by closing her eyes in close combat.
30:37The mouse takes successive small bites.
30:41With each,
30:42she further immobilizes the centipede.
30:45She needs him still to eat him safely.
30:49This desert king
30:50has lost his crown,
30:52and he makes a 100-foot-long sub
30:54for the new queen.
31:02Just like the desert,
31:04the wide-open plains of Africa
31:05reward the fearless.
31:08It's early morning
31:09in Kruger National Park, South Africa.
31:12As the sun gets hotter,
31:14most animals find shade.
31:15But this clan of spotted hyenas
31:19is fired up.
31:21Last night,
31:22they took down a 1,500-pound buffalo,
31:25the weight of 10 hyenas.
31:28But this huge feast
31:29was stolen by their eternal enemies,
31:32lions.
31:33These rivals clash
31:35over territory,
31:36prey,
31:37and even leftovers.
31:38They fight to the death.
31:43With a feast this size at stake,
31:45neither side will back down.
31:48The king of all big cats
31:50goes head-to-head
31:51with the strongest jaws
31:52of all mammals
31:53in an epic showdown.
31:59This clan of hyenas
32:01is trying to take back
32:02last night's kill
32:03from the lions who stole it.
32:06Spotted hyenas
32:07have strength in numbers.
32:10They live in huge clans
32:11of up to 80 members.
32:13But their mega-weapon
32:14is their bite.
32:16The hyena's skull
32:20is built to support
32:21the immense musculature
32:22of their powerful jaws.
32:24Their 9-inch-long lower jaw
32:27is packed
32:28with specialized teeth
32:29that resemble
32:30conical hammers,
32:32ideal to break bones.
32:35In one bite,
32:37they can apply pressure
32:38of over 21,000 pounds
32:40per square inch,
32:42enough to crush concrete.
32:44Using a pack strategy,
32:47they can kill prey
32:47much heavier than them.
32:50While hyenas dominate
32:51by number,
32:53lions dominate
32:54by strength and size.
32:59A large male lion
33:01can weigh nearly 600 pounds,
33:04over four times the size
33:06of an average spotted hyena.
33:08It only took these seven lions
33:11to steal the kill
33:12from dozens of hyenas.
33:15But today,
33:17the fired-up hyenas
33:18won't let that stop them.
33:23They're too hungry.
33:27These fast,
33:28high-pitched whoops
33:29are a clear call
33:31for reinforcements.
33:33They can be heard
33:35as far as three miles away.
33:37Using a divide-and-conquer strategy,
33:43the hyenas corner
33:44two of the lions.
33:49It's a numbers game,
33:51and this time,
33:51the hyenas have the upper hand.
33:55The lioness sits on her rear,
33:57protecting her vulnerable hind legs.
34:00The hyenas move in.
34:02It's a trigger for the lion.
34:04It's a trigger for the lion.
34:11At three years old,
34:17he's soon to leave the pride
34:19and keen to sharpen his teeth.
34:21He bites.
34:29The lion's front canine teeth
34:31measure up to three inches.
34:33They're perfectly spaced
34:35to slip between the cervical vertebra
34:36of their prey,
34:38severing its spinal cord
34:39and killing it.
34:40But the young lion lacks precision,
34:44and the hyena escapes alive.
34:47The confrontation attracts
34:48one more lion.
34:50The hyenas make a quick exit.
34:52Their strategy pays off.
34:55They've distracted the lions
34:57from the coveted buffalo.
34:59The rest of the hyenas
35:00waste no time.
35:02A group of 40 hyenas
35:03can consume a whole buffalo
35:05in under 30 minutes.
35:06Suddenly, there's a ruckus.
35:14The lions are back
35:15with their full ranks.
35:20Muscle to muscle,
35:21the lions now have the advantage,
35:24and they make it count.
35:27A young male slashes
35:29through the hyena's hind.
35:30His claws can grow up
35:37to an inch and a half long.
35:39They're the ultimate weapon
35:40to grip and hold prey.
35:42The claws grow from the inside out,
35:45shedding the worn outer layers
35:46as new ones grow,
35:48keeping them razor sharp.
35:50Like a knife,
35:51they can pierce through
35:52the hide on contact
35:53and can tear the skin and flesh
35:55of a hyena in one strike.
35:57The hyena is lucky this time.
36:01He escapes with his life.
36:03The lions reclaim the kill.
36:06It's the sign to leave.
36:08The hyenas have lost this battle,
36:10but the war rages on.
36:15For some,
36:16the most savage contests
36:18play out in the most heavenly arenas.
36:21The Mexican coast,
36:23home to black iguanas.
36:25With a top speed
36:27of 21 miles per hour,
36:29these are the fastest lizards
36:31in the world.
36:32But most of the time,
36:34they just bask in the sun,
36:36Caribbean style.
36:38But there's one thing
36:39that makes these sun lovers
36:41lose their cool entirely.
36:44Girls.
36:46The alpha male gets
36:47any girl he wants,
36:49but he has to fight for it.
36:51On this resort,
36:55these two five-year-old males
36:57engage in a bloody battle.
37:00Fights can end in death,
37:02but it's a risk worth taking.
37:04The lady-in-waiting
37:05is ready to mate,
37:07but only with the winner.
37:09These two iguana casanovas
37:15are locked in a jaw wrestle
37:17to win mating rights
37:18to the females.
37:20Romeo has his competitor
37:22in a flood of blood.
37:24He targets his jowls,
37:26the enlarged skin and muscles
37:27under the jawbone.
37:29If damaged,
37:30the competitor will struggle to eat
37:32and could starve to death.
37:33Romeo's bite is powered
37:36by super-strong jaw muscles
37:38and 100 razor-sharp teeth.
37:42His bites are crushing.
37:45They can kill his opponent
37:46through internal bleeding.
37:50But with rights
37:51to the bloodline at stake,
37:53the competitor fights on.
37:56Romeo delivers a mega-blow
37:58with his whip-like tail.
38:00Black Iguana's tails
38:07can reach 20 inches long,
38:09the length of their own body.
38:11And they're covered
38:11with rows of sharp, curved spines.
38:15The competitor retaliates.
38:23Changing tactic,
38:25Romeo leaps in the air
38:26to bite his opponent sideways.
38:30But the competitor wrestles back.
38:34The Casanovas
38:36are running out of steam.
38:42Reptiles suffer from the rapid buildup
38:43of lactic acid in their muscles,
38:45so they can only keep going
38:47for a few minutes at a time.
38:49But neither will release his bite.
38:52It's a deadlock.
38:54Digging deep,
38:56the competitor takes advantage
38:57of the terrain
38:58and throws Romeo off balance.
39:02But Romeo is on the home stretch.
39:05He finishes off the competitor
39:06with a few more spins
39:08on the battlefield.
39:11Romeo's got this one in the bag.
39:15He escorts the competitor out
39:17with just enough time
39:20to prepare for a date
39:21with Juliet.
39:27But walking away
39:28isn't always an option.
39:31Some animals won't stop fighting
39:33until one of them is dead.
39:35Sharks are believed to have roamed the ocean
39:46for 450 million years.
39:50They've survived all five mass extinctions,
39:54giving them plenty of time
39:55to perfect their fighting skills.
39:58They're the ocean's top killing machine.
40:01At three feet long,
40:07this Pacific spiny dogfish shark
40:09is no giant.
40:11But like its bigger cousins,
40:13she's a predator to be reckoned with.
40:16She kills
40:18by relentlessly pursuing her prey.
40:21One of her favorite lunching options
40:24is octopus.
40:25This giant Pacific octopus
40:28has ways to avoid being seen.
40:32His main strategy?
40:33State-of-the-art camouflage.
40:36Using specialized skin cells and muscles,
40:40the octopus can change
40:41both his color and texture
40:42to match the appearance
40:44of his environment
40:45and blend in with any background.
40:47In the much tighter quarters
40:55of a 400,000-gallon aquarium, however,
40:58these creatures are bound to face off.
41:04This octopus is trying his best
41:06to go unnoticed,
41:07but the spiny dogfish shark
41:09is on the prowl.
41:11The shark doesn't use her eyes alone.
41:13She can detect movement in the water
41:15up to 330 feet away,
41:17and she'll strike
41:18at the slightest of triggers.
41:21She can project her jaws
41:23by an impressive 30%
41:24of her total head length
41:25to reach her prey.
41:27She then creates a vacuum
41:29to suck her prey into her mouth.
41:31Interlocked,
41:32her teeth act as a sharp blade,
41:35ideal to sever an octopus arm.
41:38She senses something,
41:40but it's too late.
41:42The octopus shoots out
41:46two of his eight arms.
41:48This is the biggest species
41:50of octopus in the world.
41:56He's more than three times
41:58the shark's weight.
41:59The giant octopus wraps
42:01his six-foot-long arms around her.
42:04They're extremely strong
42:06thanks to a combination
42:07of different muscles
42:08and can resist a pull
42:10100 times his own weight.
42:11The shark tries to escape
42:15her captor's grip.
42:18But she won't win
42:20using strength alone.
42:24The shark has a secret weapon.
42:28Poisonous spines
42:29at the bottom of her dorsal fins.
42:31Almost one and a half inches long,
42:33they can puncture
42:33through the octopus's arm
42:35to inject their venom.
42:36But the shark can't get in a position
42:40to stab the octopus.
42:43Each of his arms
42:45has 240 suckers
42:47that create such powerful suction,
42:49even 100 of these sharks
42:51couldn't pull it off.
42:53The shark twists
42:54to find a good angle
42:56to bite the octopus's arm.
42:57But the octopus holds on.
43:10He'll finish the job
43:12with his kiss of death.
43:14His mouth is like a bird beak,
43:17solid and powerful,
43:19designed to cut through food
43:20covered with shell.
43:21So it's an easy job
43:23to bite into the shark's neck.
43:25He injects deadly venom,
43:26which paralyzes his victim
43:28and begins to digest her flesh.
43:32It's the killer move.
43:35Literally.
43:36Literally.
