You can always find them in the swamps being attacked by sarco, kapro, boa, and baro..

I happened to go prime meat shopping and scoop him up. Never seen one before. Loved it. Found a mate! Made them mate! Egg sit it in the water... baby Explode. Lmaoooooo never have I ever seen a Dino explode before. Was so piss off... I laughed...went to bed. Lol

Quite possibly the only completely harmless creature in the swamp.

Has a head resembling a stealth bomber, but it’s attack is only effective towards trilobites 🤨.

Bruh I have found thousands of them running out the water for no reasons

It sorta looks like a Japan giant salamander.

If having trouble finding one in the swamps try bringing a parasaur with you and use its detection ability to see all nearby carnivores hiding in the water and walk up to them to check if they are a diplo. as long as you have some sarcos or barrys to clear out the piranhas you will find one in a couple of minutes easy.

Usually is being chased By a dinosaur from the swamps

When I first saw it to me it was adorable if I tamed I would call it FLAFFY from the gaming beaver diplocaulsus ide like it to sound like this meow mow brrr brriiii mow look at my triangle he I’m a cutest thing
