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 growig 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 becaue 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. New borns will not yet have their forth spike but will instead have a bump. The Lighter colours 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, biger or smaller. It all depends on how much food they get.
