Fun fact you cant feed it a Megalodon.

Use an itchthyornis to gather fish for it. The buff increases efficiency.

Don’t be stupid like me. I was dropping fish after fish in front of it and was wondering why there’s no taming bar. Didn’t realise you have to passively feed it not just drop a fish in front of it.

They deal hundred millions of damages to fish... but only does 1 damage to other creatures

ok

The most frustrating thing about taming these guys is not only do they take a lot of fish but the same button to feed them is the same button to drop the fish(i don’t know if it’s different in pc or ps4)and it’s constantly swinging around your face making it annoying because you’re constantly dropping it. Either make it so the controls to feed them are different then dropping it or make ur so it’s not constantly in ur face.

Quick tip that helped me tame one on ASA; you can place a wooden cage on top on it when it stops moving and feed it fish through the bars. Sometimes it might glitch out but just pick the cage up and put it back down on it again. Hope this helps!

Tame to this kill fish and drag there body to it and once tamed if you feed them more dead fish corpses it will build up and lay a golden egg which is used as a buff to certain dinos or oil or a player buff

Feeding them sabertooth salmon seems to work the best.

Here's how I tamed one using Ichthyornis. 👇

What I did was use my Ichthyornis to Hunt fishes and bring the dead bodies for me.

Change his settings to "Hunt and retrieve", put him on your shoulder then you go swim. While you are swimming aim at The fish you want and double tap F (on PC). Ichthyornis will fly, kill the fish and bring the body to you.

Then you take the body to Hesperornis and feed it. Once you get used to it it's very fast and easy. I recommend following Hesp from behind so you dont need to adjust your aim all the time.

You can do the same to tame Otters.
