The Giant Moray outside of its shell.

The Giant Moray is a very large moray eel which guards a pair of the Asterite's globes in the Moray Abyss. Strangely enough it resides inside a giant shell discarded from an unknown sea creature. The shell itself is very spacious, as the moray can fully exit and re-enter it any time. Ecco defeats it with his sonar and at the end retrieves two of the globes from its shell.
