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!
You cannot knock these out don’t try you will just kill it I advise to take a megalosaurus and pick it up and put it and a stone two by six with walls three high and ceilings Then put a Dino gate on one side and feed it through the walls. GL happy taming
My brother and I built a stone cage 2 by 3 by 3 walls high and a stone Dino gate. Then use a megalosaurus to pick it up and put it inside be careful it drops sometimes trying to get in. Once inside will stick its head out and you can tame it easily. P.S. it can fit through doorways when trying to escape
In Ark survival evolved, you can tame these in the Artifact of the hunter cave here there is a deep pool of water not far from the Artifact itself, but you can find an arthropluera in this cave and if u have an otter send it after Trilobites in South zone 1 there several there and if your lucky your otter will find black pearls needed for the broth of enlightenment and your welcome now you know how to find one hard to get ingredient. (If there are no tributes is SZ1 some mention finding some at Cragg's island near the red obe in its rivers/streams)
You can safely tame one from the back of a scorpion as I have not yet encountered any creature that will agro on the scorpion unless you attack. These things are still creepy af though. (This has only been tested on mobile)
