Primarina is a marine Pokémon that resembles a cross between a sea lion and a mermaid. Most of its body is white, but it has a long, blue, fish-like tail. It has a long snout with a round, pink nose, bright blue eyes with long white eyelashes, and long light blue hair trailing off the back of its head. A tiara-like structure rests on its forehead, consisting of a line of pearls with a pink sea star at one corner and a thin, transparent blue fin extending back over its hair.
