Some one have the answer to this help me. I went to two under water caves and attempted to tame animals. This large under water cave was attached to an above ground crystal cave. Glowing orange and had Bats,snails,acorpions etc. The underwater had sea animals. All the kinds that are hard to find Mozasaurs,Lepluradons,the scary squid. They were all greatly larger than normal and it wouldnt let me tame. Thwy would go unconscience no tame. Food correct in inventory just nothing. Gps 45.5,88.6 Let me know would love to bring home something. Ps bring a pack of Sharks its crazy hard in there.
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.
Bring more tranq arrows then you think! Mine took 100 at close range, on the body, at LEVEL 3.
I took cooked prime meat (stays better longer) and got mine in only four feedings. On an icthy they don’t chase (mobile player here) happy taming- Survivor Belle
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)
