The gastrarmo split from it's ancestor, grew to 4mm in lengh, and moved to Ittiz Coast from Clayren Coast after a storm blew some plimeba northward, where they suvived and thrived. The "wings" of it's ancestor have been modified drastically. It's front wings have been modified for breathing as well as for eating. Their back wings have been modified for movement by taking the water that is suck in through the front wing and expelling it out in bursts of speed.
