Barkbats are non-sapient, sentient species native to planet Trees in the Orion's Arm universe.
A Barkbat is a large, black predator. The tegument of the creature consists of thick vein-like structures, resembling a tree's bark, something unseen on any terrestrial animal.
The creature has seemingly no limbs other than its enormous wings.
The Barkbat lives as a large predator of the planet Trees. It cling to the trunks of skywracks, giant tree-like plants. It uses its wings to glide and hunt other creatures in the canopy.
The bark-like skin serves as camouflage when clinging to skywracks, both in dormant periods and between feedings.
