These guys are weaker than they look. I had a few low levels near my base and they died to my level 5 sarco. They’re biggest attack is when they grab you but if you just use a Dino like a sarco then they stand no chance
Karkinos
The Karkinos is a massive crab-like creature in Ark: Aberration that can grab and smash creatures and players. It can also throw them at great lengths. Using its strong legs, the Karkinos can leap to impressive heights.

Player-written tips for taming, using, and fighting the Karkinos in ARK: Survival Ascended & Evolved.
Everyone says you need a catapult or cannon, but you don’t. It gives the WORST taming effectiveness, but you can use a rocket launcher. Find a karkinos lv. 12 or higher. If it is not, lv. 12 or higher, a single rocket will kill it. After you find one lv. 12 or higher, take a…
Everyone says you need a catapult or cannon, but you don’t. It gives the WORST taming effectiveness, but you can use a rocket launcher. Find a karkinos lv. 12 or higher. If it is not, lv. 12 or higher, a single rocket will kill it. After you find one lv. 12 or higher, take a fast tame and agro the karkinos. Once angry it will follow you, move a small distance away, it will move toward you, showing it’s face, fire your rocket at its face. This will almost kill the karkinos, but it will deal lots of torpor. Now use your fast tame and kill something, get really close to the body. let the karkinos come to you and attack you but in the process of trying to hit you, it will hit the body. This will heal the karkinos completely, allowing you to repeat the process until it is knocked out, feed spoiled meat (as they like that the most) until tamed. Have fun with your new karkinos! 🦀
If you do too much damage when trying to KO. Use honey on last spot of hot bar and toss at its face for speedy hp recovery.
Shoot from the front with a cannon, catapults don’t work anymore.
Pulls players of saddles don't fightitwith small tames
Catapult its body to knock it out
Even though it's mainly a water dino, it can still pose a threat to you on land, so be careful!
Yo if you tame a Karinos you basically shoot with a cannon or catapult, you knock it out, feed it, and it loves you forever, after you shoot it in the face with a giant metal ball or boulder 🥺
I just tamed mine with a Paracer with a catapult on it’s back
I recommend creating a trap using some dinosaur gates and a large bear trap. Because they are very hard to keep still!
What makes polymer on Aberration, Valguero, and Fjordur a walk in the park. There are other maps but I have yet to go there (as I decided to do all notes and bosses run). I have harvest setting set to 3.0 so some dinos yield more from the body of a karkinos than others.…
What makes polymer on Aberration, Valguero, and Fjordur a walk in the park. There are other maps but I have yet to go there (as I decided to do all notes and bosses run). I have harvest setting set to 3.0 so some dinos yield more from the body of a karkinos than others. Moschops can harvest more with the secondary attack with bonuses based on organic polymer bonus by percentage in levels if that makes sense. Regardless of dino you will come home with probably a lot of organic polymer.
You can use a net and a cannon only at the main part of the body
All you have to do it net it, set down a catapult and go to town. Very easy yame once you get the hang of it. Just make sure you do it on flat ground!
The Karkinos and the Anky is a great way to farm metal in aberration in the blue zone.
Karkinos grab their prey if it is small enough and bash it prey up and down. Best way to get away from one is by running. Karkinos are slow and won't catch up in time you don't spot running!
Can carry utility dinos like anklusaures and more.
HOW DOES IT ONLY TAKE 37 CANNON BALLS TO KNOCK OUT A LEVEL 9999????
Responding to the person who said the how doedics swing castaroides should attack trees if you pick them up but that may not work anymore...
This Is a great tame for material runs. If you have 2 people, you can use any material-getting tame and the crab. Just pick up the tame while someone is riding it and go farm away.
Grab two arthros with bobs on em and let em destroy any base you want.
