Just a idea I whipped up awhile ago. It has no purpose but it probably cant be too hard to give it one. Maybe it has posion by defult or speed in water or something. (Depending on the design)

Sorry the art is so bad, using a laptop track pad. Took ages. There are two designs, fish tail and spike tail. Spike tail also has bone plate armour along its tail. This creature could drag itself around on land and be a rather flat target. If the one with the fin as the tail is used it could be used to fill the role of a water creature for the alien side, since it would fit with the water theme and any water abilitys would make sense. (Maybe extra speed or something?) It would also be able to drag itself out of water and work just as well above ground, because its a flat long target it may be hard to hit, giving it some use. If the spike tail is used, I think posion may work pretty well with it.

Parts of the creatures can be mixed and matched in the design and it will always work. (The fish one can have plain claws, armour. The spike one could have spike claws and no armour)

Nice maybe that can be a desert alien too that goes into the sand.

Think of it a tiny centipede type sand alien.

it looks pretty nice like swimming alien, and without fin it'd be like desert scorpion

but it looks like some sort of crossbow

The front legs would we pointing downwards like a mara or something, so in game it wouldn't look too much like a crossbow xD

Hmm, maybe that water ability should be really added to one alien. Nothing will change on dry but in the water will be much faster. That could help game balance in the water.

Sorry the art is so bad

LIES.
I like the fin-spike combination idea. Could probably make it so the front legs makes it lunge forward, and click right click (Secondary) to do a scorpian-like stab of some sort... but the animation would look weird when he lands though...

Looks good, keep it up.
