A marine crocodile that appears in To Hell...and Back.
A marine crocodile that solely lived in the water as opposed to the other crocodilians of the time. It developed flippers instead of feet. It had a rather small snout when compared to the larger cousins. Most unique was the fact it lost it's protective armor to gain speed so it could out run larger marine creatures.
When Nigel swims in the ocean he watches as these creatures ate and hunted the peace whales at the time.
