Vicefang Nailfin

The vicefang nailfin has split from its ancestor and has adapted for a soley carnivorous life in the open ocean. The vicefang nailfin has adapted a sleek snake-like body. Its front limbs are shorter than its ancestor, but its "nailfins" are much larger as well as broader. The rear limbs are slightly shorter and are used in steering. The front half of its body has a ridge of skin that helps keep it level so it doesn't roll over when swimming straight. The ridge can also be lowered when it is feeding to allow it to do complicated maneuvers when attacking prey. It also only goes onto land to give birth, it rests in water. Because of this all of its eyes are at level. Its rear teeth are adapted at piercing and slicing flesh. The top front tooth bottom front teeth form an interlocking vice-like trap. The neck is also shorter and has extra jaw-closing muscles. Its movement adaptations have made it slightly slower than its ancestor. But using its wide front paddles and its snake-body in addition with its rear steerin limbs, it can outmaneuver prey with ease.

The vicefang nailfin still lives in groups and hunts in similar ways, and uses complicated maneuvers to drive prey closer together. They can also dive deeper to use teamwork to kill large prey like the rudderhorn. They bite and pull back with their front teeth, inflicting gaping wounds.

The vicefang nailfin only goes ashore to breed. They don't prefer a certain coast, but certain groups prefer different coasts. It moves poorly on land in a clumsy slithering fashion. It also has bad eyesight out of water. The females shed their teeth when close to giving birth to avoid harming their young as they are passed out of their mouth. The teeth grow back in a few days. Because of this the females don't eat when they go to the coast. The males will scavenge when waiting for females because they are unfamiliar with coastal fauna.
