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. 。
