Crawdaunt are large, mostly red crustacean Pokémon. They have three pairs of limbs in total: two pincers with spikes protruding from the edges and tan-colored lower sides of the claws, one pair of legs that resembles Corphish's with small spikes, and a two-clawed back pair that looks almost elephantine. They possess two blue stripes on their chin that are sometimes mistaken for a pair of lips. Lower on their tan-colored underside is a pattern of angular red shapes, separating the upper portion of their underside from the lower portion. On the top of their head is a yellow star-shaped object, the purpose of which is currently not known. It may just be there for show. Crawdaunt has circular eyes with small pupils in dark sockets, and a pocketing in its shell below its eye resembling 'bags'. On the lower part of its lobster-like tail is a triangular patch of yellow.
