Tips & Strategies

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
You can tell if you shot the legs if it throws it’s arms up in the air when you shoot. If it doesn’t move at all when you shoot that means you shot it correctly, so make sure you don’t get it to throw its arms up when you’re nocking it out
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.
How do you stop it from jumping out of the trap
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!!!
I understand that all the previous tips submitted were useful, but just in case it was not clear, hit the TOP OF THE CRAB, it will have a special animation if you hit it in the correct spot, and will take only a small amount of boulders to tame, even a high level. (Irrelevant with Cannons)
If you're carrying a tamed Doedicurus in your claw the Doedic will automatically start harvesting any stones you hover him over. Just start pumping points into your Doedic's weight because it will stop at about half of its own carry weight. I've yet to discover another tame it will work with though...
Watch YouTube video from captain fatdog karkinos trap and use this to tame them. I struggled so many times and then I realised you can't do it going up a hill. Flat surface and hitting it in the head are the two main problems but as soon as I had got it right it was so easy.
Up for noobs
I’d say I’m having pretty bad day. So, I just bought Abberation and I was so excited, so I went over to the water. I don’t know much about Abberation, so I thought the Karkinos was just a kind little crab. Oh boy was I wrong.. I went closer to the water, as I was thirsty. But the Karkinos comes running up to me, picks me up and shreds me to pieces. Let’s just say I took a little break from Abberation 1 minute after I bought it.
TRANQ ARROWS DON,T WORK you haft to shoot a cannonball shoot it in its head if you shoot it in the leg or it will die. Up if helpful
It's a Giant crab that can throw it's enemies far away
Net projectile works on these, so craft your catapult and boulders, find your crab and net it. Proceed to set up the catapult a few feet from its face and you can easily just fire all required shots before the net expires. You’re welcome!
