Hyaline crayfish

From Halopedia, the Halo wiki

A hyaline crayfish is a type of crayfish native to Gao. Undoubtedly named for their glassy appearance, they were known to live in the drainage conduits under Covert Support Base 4276 prior to its destruction, and were tended there by Roams Alone.[citation needed]
