LV-1201 Chameleon

Chameleons are an extremely dangerous species of non-sapient reptilian predators from the planet LV-1201. They're so named for their camouflaging ability to crouch into a ball and change the appearance of their skin to resemble a moss-covered rock.

Biology
With short legs and long arms, they have a distinctly simian look which allows them to alternate between bipedal and quadrupedal posture.
