A crab is a (typically) small crustacean that is often found on beaches. Crabs have high armor, as the shell would imply. Crabs are typically neutral and ignore passersby. They drop claws and meat that are used in cooking recipes (e.g., Crawler Meat for making Crab Cakes). Crabs are found in Durotar, The Barrens, Darkshore, Westfall, Blackfathom Deeps, Ashenvale, Desolace, Stranglethorn Vale, Azuremyst Isle and the Swamp of Sorrows. They are usually found along the coastline in some watery zones. Sometimes, they may appear as critters. One can even find tiny red lava crabs scuttling about in the Searing Gorge and Burning Steppes. Crabs are not skinnable.
