Can be grabbed by the Kaprosuchus. If you're careful, you can walk around on land with the Ichthy in your grasp. If it touches the ground, it will die.

First time taking the Megalodon for a spin, thought they were aggressive when they swam up. Turns out they're just curious little guys then they'll swim away eventually.

Go to herbivore island (The island) at the right bottom. Go to map if unsure. Look around and you should find some itchyosaurus. But be careful, in the water they look like sharks, don’t mistaken them as sharks they have a pointed snout. Like if you found it helpful! :)

There were suddenly like 5 of these in my river that is only 3 feet deep or so

I’m pretty sure they make compy noises. I was trying to tame one and I kept hearing a compy, like really close. But it confused me because compys shouldn’t be underwater but nope, it’s an ichthyosaurus.
(I don’t know if it’s a bug or something but it’s kinda funny)
