V. Nyeheyus will split into two different species, V. Postorulus and Nyehus Sirproditor.
V. Postorulus will gain muscles at the back of it’s tail fin, and begin to lose the gills at the back of the two tagma, while also flattening and tilting backwards the gills along the middle of it’s body so as to improve respiration. Shoal sizes begin to decrease dramatically.
Nyehus Sirproditor will lose the enzymes that allow it to digest Vermis, instead turning into herbivores that strafe through the clouds of M. Oceanus and V. Viriditas. Their frontal tagma will grow shorter but wider, acting like funnels to gather enough of the material that they need to eat. Shoal sizes stay about the same.
V. Nidi will grow a dappled darker blue on it’s top, while also growing out the fins on the frontal tagma, allowing it to do a sort of breast-stroke to dart through the water and catch it’s prey. It has also developed “osteoderms” inside it’s mouth that are abrasive and help to shred down it’s catch.
