Interesting Facts: Diplocaulus was an amphibian that could walk on land but could also survive for a long time underwater. It probably hid in mud or rocks at the bottom of the river or lake then jumped out and snatched its prey with its sharp teeth. Ow!

Its head looked like a manta ray, don’t you think? That large head may have stopped some predators from eating it: they couldn’t get their mouths open that wide!
