Zeb

Zebs are a species of aerial, pit-dwelling insectoid indigenous to the subterranean jungles of Brinstar, one of the planet Zebes' many sectors. Two hues were known to exist: red and a yellow, either indicating closely related subspecies or sexual dimorphism. They typically could be found living in large colonies within former colonial air ducts and like many other Zebesian hive-oriented fauna, they would protect their homes with ample ferocity. 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.
