Find these in the Cave In The South. They like near the river. Just eat some bug repellent and feed meat! I have not tamed one but I DID get SUPER close before mistaking a dung beetle as a spider and punching it. Yes, dung beetles live there too!
Easiest and safest way to tame this is to lure it under water. They stop aggro and you can tame as you please. Just make sure you come up for air every once in a while. Also be sure the water is deep enough.
