Orthacanthus was an ancient Permian shark that had a long spine growing from the back of its skull. It had a very long dorsal fin, which ran all along the sharks back, giving it an eel-like appearance.
Orthacanthus was an apex terror of freshwater swamps in prehistoric North America. Its body reached nearly 10 feet in length, and its powerful jaws were lined with double-fanged teeth.
Orthacanthus lived from roughly 280 million years ago during the end of the Permian period. They were around before the dinosaurs evolved. This makes Orthacanthus one of the most famous predators of all time. Males and females were highly different, but no one really knows if males and females were ever present in the species Orthacanthus.
Orthacanthus may have been sometimes a cannibal, feasting on others of its kind. This is also shown in some animals of the present day.
