Skrelp is a brown aquatic Pokémon that resembles a marine animal similar to a seahorse called a sea dragon. The tip of Skrelp's tail has three leaf-like fins. Skrelp has a pair of roundish, clear pectoral fins on the sides of its body, a dull purple belly and a blunt spike on its hunched back. Skrelp's face is the same colour as its belly, with an upward-pointing snout and red circular eyes with small black pupils. A clear, roundish growth with a brown stem sticks out on the back of Skrelp's head.
