Physiology and ecology
Adult Kra are 30cm long, covered with thousands of sharp spines. The 'wings' are formed from a mat of hollow spines that extend out from the upper body like circular rotary blades. Kra take oﬀ by means of a natural jet propulsion. The creature builds up gas from its food, which it stores in inﬂatable gas sacs under the belly. When it requires lift it expels this in controlled bursts out through the hollow tubes that form the wings. This causes it to rise until it reaches the powerful thermal currents of the trench where it can rest and allow itself to glide.
Kra live in large ﬂocks, of approximately twenty thousand adults.
When hungry or frightened the flock swarm over any animal, with the spines tearing through skin and hide. The Kra live on blood, lapping it up with 20cm tongues coated with a highly effective anti-coagulant.
