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.

Unless I am missing something, the Quetzal CANNOT pick up the Karkinos with their feet.

Make sure to carry around grappling hooks
If picked you can graple the crab and it will let go

Jumps super high and can launch stegos ... two at a time RIP turrets lol

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.

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.

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...

It's a Giant crab that can throw it's enemies far away

Be careful when carrying a Dino that has a tribe mate mounted on it. I was walking up a hill carrying my anky with a tribe mate on it and they went under the map and died. RIP ANKY AND SHINEHORN. Tribemate was eh anyway.

Knock out with catapult. Make sure to hit body to do torpor. Hitting legs damages it and doesnt knock it out. Shove rotten meat in it.

Using a cannon will ko any level crab in one hit, but will SEVERELY drop taming effeciency. If you want one quick, use cannon. If you want a high level use a catapult (the inferior siege weapon).

The Canon Knocks 150s out in one shot to its core! Upvote so people can see.

Trap it with bear trap and shoot catipults into its body to KO

Basically the new quetz. Super weight and can carry tames to harvest resources and then throw them back into the base ;)

Up this if you think they should add the amount of boulders it takes to knock one down⚡️

Knock theme out by firing boulders at their body. Each successful hit adds 250 torpor.

You can fire weapons while riding it. Hold a creature you'd like to tame, then tranq it while your crab holds it in a claw - makes solo taming easy!

They are immune to radiation and are great for leaping past danger when trying to get a rock Drake egg.

In the wild crabs and spinos are buddies... they use the buddy system...

They can walk over spiked walls.
