Zolall
this unusual predator was native to the planet Merisee. A nocturnal hunter, the zolall was a hairless, slippery, smooth-skinned creature which could glide through the air by filling specialized sacs in its abdomen with air. These creatures had floppy, triangular wings, but they were ineffectual for flying. Zolalls could control their flight by moving their long tail. These creatures used their sharp fangs to inject a poison into their prey, and the poison was actually "harvested" by the assassins of the Loag for use as a weapon. Zolall were somewhat trainable, and many of the Loag used them as watchbeasts at their bases.
