Skrelp is a brown aquatic Pokémon that resembles a marine animal similar to a seahorse called a leafy sea dragon. The tip of Skrelp's tail has three leaf-like fins. Skrelp has a pair of roundish, blue pectoral fins on the sides of its body, a purple belly and a blunt spike on its hunched back. Skrelp's face is the same color as its belly, with an upward-pointing snout and circular red eyes with small black pupils. A roundish, blue growth with a brown stem sticks out on the back of Skrelp's head. It somewhat resembles Horsea in body shape.
Skrelp can be evolved into a Dragalge at level 48.
