They were not deep sea reptiles but instead they lived close to the surface to hunt for fish. Despite that they where top predators eating anything from small fish to the large Plesiosaurus. The most notable family is Maisie and Marvin. They also has semi-crescent tail fins and they used their tails to swim, not their flippers.
