Very easy to tame if you know what your doing. First tame an Ichthyosaur. Then grab a crossbow and some tranq arrows and find one and knock it out. It is not be able to attack if you are on the Ichthy. As you are taming it, be sure to remain on the Ichthy unless feeding narcs, so other creature don’t hurt you.

These are one of the few dinos that take less damage/topour from head shots. Aim for the body.

When it says 1.7% chance of death. It means it's going to die.

If your on ark mobile grab a crossbow (a good one) a good underwater tame and the scuba set so you don't drown.i finnaly tamed a plesi with this method and now it's time for taming the dunki (I am coming armoured shark)

A easy tame but be sure to bring lots of tranq arrows it took me 79

Took me over 150 tranqarrows with a 400% crossbow to ko an X-Dunkleo... what a pain lol

Be sure to bring lots and I means LOTS of tranq arrows 150 at least to be safe avoid head shots....obviously

Just tamed a 140 X Dunky. Yeahhh, really recommend that you build a trap for these peeps, spent 40+ mins trying to knock out this bad boy with a decent crossbow all while dodging tussos ect. Good times, stressful but good.

They are found in deep ocean water
