Zoa

Zoa are a fully aquatic, pit-dwelling crustaceanoid indigenous to the subterranean lakes of Maridia, one of the planet Zebes' many sectors. Blue-hued exoskeletal, backswimming organisms, they typically can be found living in large colonies within sand traps and like many other Zebesian hive-oriented fauna, they will protect their homes with ample ferocity, however, Zoa often attack in groups of three, for unknown reasons. They will continue to bombard their foes with their seemingly endless numbers until the threat flees.

As with all other species native to Zebes, it became extinct in the wild when Samus Aran finally destroyed the evil Mother Brain.
