Alien Species

Flesh-Eating Beetles are a species of giant insectoid predators which can be found in pits on planet Mars. Despite their savage nature, they have demonstrated the capacity to speak simple sentences, suggesting that they could be at least semi-sapient.

Their natural diet seems to consist of Martian Zombies, although they will not hesitate to eat Humans who may find themselves in the Beetle's territory as well.
