Littoralope

Littoralopes are small, numerous aliens that live throughout Darwin IV. In Expedition, Barlowe encounters a small herd taking shelter in the decaying skull of a Sea Strider, and noticed that their entire bodies glowed green on the darkness. He then witnesses the entire herd feed on the Amoebic Sea before leaving them.

Littoralopes played little significance in Alien Planet. They took a role of running away, or prey for Skewers. Their only real defense is to scatter in all directions, forcing predators to target one individual.
