Crab

Crabs are creatures who live at the bottom of the sea. In RuneScape, they are found only in an undersea crab pen located in a Mogre Camp off of Port Khazard and the Dragontooth Shipwreck off the coast of Dragontooth Island. Crabs can be killed for Crab meat, which is an ingredient of Cooked fishcake. They will occasionally drop a Fresh crab claw or Fresh crab shell, which can be crafted into a Crab claw glove and Crab helmet, respectively. They will also sometimes drop an Oyster.

The mogre camp area becomes available after beginning the Pirate Pete portion of the Recipe for Disaster quest. Players will need to speak to Murphy in Port Khazard and have him fashion a Fishbowl (supplied by the player) into a Fishbowl helmet and Diving apparatus, after which he will assist them to travel to the bottom of the sea. The Dragontooth Shipwreck requires reaching a certain point in the Rocking Out quest, and also requires wielding the necessary diving gear.

Smaller crabs can also be found on beaches around Gielinor, such as south of Port Sarim and on Mos Le'Harmless. These, however, are unattackable, and are essentially just scenery. Their examine text is "No one likes crabs..."
