Buffalopterus strikes fear into the hearts of those who behold it. Its body resembles a terrifying fusion of arachnid and aquatic predator, covered in a thick, chitinous exoskeleton that gleams with a dark, oily sheen. Its body is about a foot in diameter with eight spindly legs, a bulbous tail, and two powerful pincer-like claws extending from the front of its body.

Buffalopterus inhabits shallow coastal regions, where it lays in wait among tangled seaweed and rocky outcrops, ready to ambush unsuspecting prey that ventures too close.
