Hidden beneath its tusk-like shell is a jet-black, slippery and slimy sea creature that looks like it came off the set of。 Alien。.。
Scientists said on Monday that they've discovered the first living specimen of a giant shipworm in a Philippine bay.。

Via Giphy 。"To me, [finding the giant shipworm] is almost like finding a dinosaur -- something that was pretty much only known by fossils," Dan Distel, research professor at Northeastern University, told the Guardian. 。

The discovery is akin to finding the "unicorn" of mollusks. 。

that the team discovered a population of the shipworms, and sent five of them to a laboratory, where they opened the giant shipworm's hard, calcified tube.。She said it was nearly as heavy as a branch.

Unlike its shipworm cousins, which burrow into rotting wood, this giant shipworm, K. polythalamia。
lives on hydrogen sulfide, that which gives eggy farts their potent kick. 。
K. polythalamia 。rarely eats anything else -- its digestive system is stunted, and scientists have found little to no fecal matter in its body. 。
Hydrogen sulfide -- released from decaying vegetation and rotting animals in the swamps where it lives -- is digested by symbiotic bacteria that lives in the giant shipworm's outsize gills. The bacteria then produces carbon compounds the giant shipworm consumes.。 Via Giphy。There are still many questions about the giant shipworm -- for instance, scientists have yet to discover its life cycle, and how to measure its age.。
"Are the specimens we studied a couple years old, or a couple hundred?
