WATCH: After centuries, scientists finally found this freaky 'unicorn of mollusks' in the Philippines

The giant shipworm, which has the scientific name Kuphus Polythalamia, has eluded scientists for centuries. Scientists have known its large tusk-like shells measuring three to five feet since the 18th century. The creature living inside, however, has never been seen until now.
