Can be picked up with arghh and put into wooden structure to knockout with tranq arrows, amazing find

NO SADDLE REQUIRED. Can only ride while in water, and you WILL fall off even in shallow water. You must mount in water, not on the shore or in a river. --AK

Don’t kill it! It is nice. It scared me the first time I saw it

I just tamed one she is epic if your a mobile player like me then get one

Don’t worry there rideable for mobile players as well but you can only ride them underwater

So apparently this Dino in baby stages is like a tadpole and has to remain in water. I podded two juveniles and threw them out on land and they both just disappeared.

Keep them in water the full duration or it will disappear

.

You can also pick it up with a petrodon

You can only mount these guys when they're swimming!

They don't have the best health, but amazing speed underwater and you can even get oxygen from them. They're somewhat rarer on ARK Mobile, but found in swamps being attacked by 12 local Kapros.

They're skittish like Ovi's and Archy's, but easy to get down and can be carried by Argys or larger, tamed or not.

This is very useful for underwater adventures, upgrade its oxygen and health(health for it to not die immediately) and you can have a lot of oxygen underwater, in sacrifice for some of its

Always wondered what they were used for until I tamed one. Really good for black pearls

These guys are usually slept on but they are good even if you got scuba gear they can out swim almost anything in the ocean

Use spyglass to find diplocaulus

The oxygen info is white and stands out against normal yellow green and red and is larger font...

There are very week Dino so kill everything that breaths on it, around it

Found anywhere in the swamp area

An offer overlooked tame. While yes, there are better tames, if you’re an earlygame or begennier, this is a pretty good dino to travel into the sea. It can also get black pearls from trilobites really well. Oh and did I mention you can take oxygen from them if you’re drowning? Again, very overlooked and underrated tame.

When going underwater with it, bring an escort such as a megalodon

Tamed one today, it was by the Green odilisk. Brought it home with an argentavis, shot it a few times with narco arrows (bow) and fed it meat and narcotics as needed!

They look so dumb and cute, would recommend getting one

They one shot trilobites and get black pearls, they are super fast underwater. You can find them in swamps. You can get oxygen from them and use their oxygen while you are riding them underwater.

Very difficult to tame in PVE since you can’t pick it up and it’s every gator’s favorite snack. 9/10 Times you will find them getting eaten. I recommend taking a taming raft to the edges of the swamp near the ocean and using rare flowers to aggro it into your boat. Have a buddy scout with a flyer to find one. They have low health so be careful not to kill it. You might want to force feed to get the health back up after KO’d.

LIVING SUBMARINE!!!!!!!!!!!!!!

Nobody expects you to be built at the bottom of the ocean with 5 of these, very good hidden base

When i tame a high level diplocaulus i am happy i ride it at the water and i think i must give all my items to my basilosaurus then i shock it is super duper fast

warning: diplocaulus if you use diplocaulus oxygen he/she will give you oxygen but it has limit your using diplocaulus oxygen that’s not infinite oxygen most of people submit infinite oxygen
