Sinister Capiri

The sinister capiri split from it's ancestor, the vengeance capiri. The newly formed spike on it's back helps hold up it's ever growing sail. It's false mouth has become very hard and will be used to ambush it's prey by ramming into it before clutching it. They had to migrate because of constant fights between it and it's ancestor. They usually are found in packs of 8 and will stay together at all times unless they are hunting. Newborns will not yet have their forth spike but will instead have a bump. The Lighter colors help it blend in a bit better near water and in warmer areas of the plains. Each sail is different, they may be slightly lighter or darker, bigger or smaller. It all depends on how much food they get.
