Cimex, the Cave Predator (BCBS July 2012 Entry)
Alright, this is my alien for the challenge. It is a creature I've named a "Cimex", and is native to the caves of a low gravity planet orbiting a blue-white star. No life can exist on the surface, but the planet is honeycombed with semi-submerged caves. And life thrives in these caverns, dimly lit with bioluminescent flora...

Side view.

Forward view.

A view of its large mandibles, built for plucking unwary fish from the water. The bioluminescent patch on its head attracts fish. The creature also can heighten its body temperature, and the warmth attracts prey as well.

A view into its jaws and throat. The creature does not chew its food, but instead grinds it along multiple sets of sharp mandibles.

Thanks to its homeworld's low gravity, Cimexes can hold their large, muscular tails high!

Even on alien worlds, one is not free from parasites. These small, round, leechlike creatures extend tendrils through soft patches in the Cimex's exoskeleton and suck nutrients from its muscle and bloodstream.

A side view of the head. The creature does, in fact, have primitive eyes, but these organs are weak, and can only detect light emitted from some plants, funguses, and other Cimexes.

The large, bony tail seems to have once been a fin. Perhaps the creature had a water-dwelling ancestor?

Well, the tail now performs a new function. It has evolved into a claw-like trap, which the Cimex can use to catch prey, feed, or fight with.

The Cimex's exoskeleton is very flexible, and so the creature can feed itself with its tail.

The creature with its young. Young Cimexes have oversized mandibles, and lack their tails. They will stay with their parents until they develop the proper proportions.

In the meantime, both parents (male and female) care for the young, providing food, shelter, and transport to their children.

A female Cimex can lay between two and ten eggs after mating.

An interesting fact is that female Cimexes actually farm parasite colonies on themselves, as the small leeches provide an excellent food source for its children.

Rear view of the tail.

Uh-oh. It appears we've offended the Cimex in some way! Time to move!


Behind the Scenes:

I actually took a lot of inspiration from the Chaurus from Skyrim for this creature.

Good luck to everyone else in the contest! DEUS VULT!!!

A very well-thought out build... especially the biology. Perhaps you are a budding Astro-biologist?! Cool! :)
