Botwoon

A Botwoon was a large, aquatic serpentine predator indigenous to the planet Zebes. Their size appears to indicate that they are apex predators in the Maridia zones in which they live. They make their lairs in multiple connecting holes, presumably dug out by them. They are capable of spitting a number of green objects of unknown origin in a spreadshot pattern; also, their bodies are apparently flexible enough to dodge any attack, forcing the only useful weak point to be their head, however they are immune to beam weaponry. As they are injured, blood rushes to the surface of their skin, turning their skin deeper reddish tints as damage continues to be incurred. Botwoons are also notable for swimming by using a body-length undulating fin and a horizontal caudal fin.

Only one Botwoon was ever encountered by Samus Aran, and so it can be speculated that they were either rather uncommon or rare, or simply that they had very wide territories (which would seem unlikely since they did not appear to have any ability to move to other locations). This single Botwoon had been trapped in a room by the Space Pirates, although whether this was to block off its attack towards them or if it was purposefully placed here by the Pirates as a sort of "guard" is unknown.

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