Any water-rich planet would be bound to have some kind of bizarre life forms. I like the idea of alien life forms on water planets, and I used what I know about ocean creatures to come up with this design. This creature is related to cephalopods, only it's got an almost primitive hard shell and a tentacled underbody which can retract inside the shell. It has five pairs of eyes on top of its shell, and a cruel toothed mouth underneath it's belly, which is ideally suited to grind through the shells of other creatures and suck out the contents. The tentacles are a perfect accompaniment because they can grab and squeeze their prey and hold it while its being eaten. I'm still working on this one, I think it needs tiger stripes and spots, for better camouflage. All the better to sneak up and eat you, my dears.
