Saucetea

The saucetea replaced its ancestor, the swimming sauceback. It has become more streamlined in shape and its fin-hoofs have become larger while its legs have become smaller. It now uses its caudal fin as the main means of locomotion. Their swim bladder has become more advanced to allow it to stay underwater without rising or sinking. This is good when it lurks under the water and ambushes it prey.

Their mandibles grab either side of its prey like an ant lifting dirt. They are hooked backwards so prey cannot escape. Their side micro-lungs have moved even farther to the top of the body so it will not have to expose too much of its body to breathe. They can close up watertight when underwater. They can smell things both under the water and out of the water but their ears only work outside of the water. One would think this would mean they would be "blind" when swimming but they can use their carapace to pick up underwater sound waves. They will make high frequency chirps to use as echolocation underwater. Thus it uses its ears when above water and carapace underwater to "see" its prey.

The females must climb up to the shore and lay their eggs in the sand like Earth sea turtles. Once hatched they will grow up on their own.
