Kakaru

The Kakaru is an avian reptile native to Shakuras, an abundance being found at Kakaru Keys. It is the only critter that can fly. The kakaru's ability to survive on this virtually lifeless world is a mystery.

Interestingly, if one of these creatures is slain in-game, it disappears in a blue flash.

Trivia
The name of this creature could be a variation on Kakuru, a small Cretaceous theropod.
