With thin, torpedo shaped bodies, they glide and soar on a pair of flexible wings, steering with  horizontal tail fins, sometimes in flocks of hundreds.

 

Their main sensory organ is a bulb at the anterior end, which tastes/smells chemical changes in the atmosphere, allowing the Kai-wip to locate food, detect atmospheric changes and maintain social groups.

 

The more primitive Muradi Kai-Wip and Greeni Kai-Wip also have small photosensitive eyes around the sensory bulb.
