Ghost Capiri

The ghost capiri split from its ancestor, the phantom capiri, it is now nocturnal, and has changed its colors to match, it is now an omnivore, and attacks while its prey is sleeping. If it is spotted, the predator would only be able to see the glowing sail, which shifts to and from many ghostly colors, intended to scare the predators away. The ghost capiri's tail now has more armor and is longer, but now no longer resembles its head, so it developed three barbs on the underside, so it can be used as a weapon.
