Cave Crawler

The Cave Crawler is a aggressive life form located on the habitation ship Aurora.

The Cave Crawler cannot swim, but it also will not drown. Rather, it walks and jumps around. If the player touches it while it is on the ground, it will damage the player.

Cave Crawlers move in groups, typically falling from the "ceiling" of the Aurora and are aggressive towards the player, jumping towards and damaging the player when approached. Cave Crawlers are also able to climb onto the walls and ceilings of caves.

Appearance
The Cave Crawler  is a bluish-gray four-legged crustacean. It has a large, bioluminescent, blue and white spot covering most of the top of its body, which may be an eye. The Cave Crawler  has two mandibles on the front of its body, which are presumably used for feeding.

Trivia

 * These creatures bear a great resemblance to the spider creatures from the movie Lost in Space: They have disc-like bodies, they're hostile towards the player, and they roam around a derelict terraforming ship; much as the creatures from the movie roam the Proteus, another derelict ship that appears to have items on board for habitizing a new planet.
