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

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

I killed one with just a bow and movement speed back up shoot turn around and run a little turn and shoot easy way to kill plus lots of chitin and organic polymer easy just bring enough ammo

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

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

They can walk over spiked walls.

It'll drop you if you log out.

Has a slow reaction time and you can usually avoid it attacking you by running under its legs.This might change in later patches

They often spawn near the lake by the portal in aberration so if your looking for one be careful and don’t swim to deep!

They drop Organic Polymer when you harvest their corpse

Can be used to tame aggres-passive dinos (e.g arthropluera) more easily by grabbing them since it doesn't drop them when you dismount like argentavis.

Beware of the front as they do a smash attack with their claws. They also have a pick up move which can pick up small dinos.

Throwing a plant z grenade can cause a Karkinos to drop you or your dino. Essential when traveling on Ravenger back.

Be careful when attacking them since then can grab you off of most mounts (including your own crab)

They seem to have a bug where a Sarco just stands under them so the can’t attack them somehow. I lost 2 craps to a lvl 10 sarco because of that.....

can be found along with ravagers and other creatures on Valguero. northeast of map, look for underground waterfall.

Then I told the police he grabbed me...

Beware, usually found near spinosaurus and they don't attack each other.

If you see these guys in the wild the aren’t as difficult to kill with a ledge and few arrows to the legs you’ll be set.

Um just tell your dinosaurs to follow you and run if your an early player
