Tranq Arrows/Darts DO NOT WORK!!! To knock this out you need to use a catapult and shoot in only on it's back. If you shoot it on it's legs it will kill it.

Cannon balls discrease taming effeciency significantly! So for high tame level, always use boulders. Please let other people know! :)

Pretty easy to tame. Trap it in a circular form of stone Dino gates, place catapult low if catapult is high the crab will die. Then shoot it with a catapult. Cannons insta kill the crab, do not use cannons

THEY CAN BREED NOW GOOD LUCK ON MUTATIONS 👍

ASA: Cannon ball to head, no effectiveness loss from the hit, single hit KO on a 150 (mine was on Aberration). Just have to time it right, make sure your cannon is properly aimed, and maybe a silent prayer. Spoiled meat is effective for the game if you don't have kibble, although kibble is probably the best idea.

If you are missing with your catapult and it's dying, drag dino corpses to it and let the karkinos eat the corpses. It will heal him up a lot then try again with the same torpor you left off with.

ASA: Catapult dont works in offical Servers. User a Canon and shoot at the Back. Build a Trap and good luck.

This tame is like the Rock elemental, but do not shoot it in the head. Shoot it right in the back of it's shell. Anywhere else will kill it fast.

To the guy who said "rare on floaty islands on crystal" that is a load of crap found 20 on 1 ISLAND!!!

Cannons do not lower efficiency, one hit knock out, catapults are broken on ASA.
