Starmie (Japanese: スターミーSutaamii) is a starfish-like Water/Psychic-typePokémon introduced in Generation I. At the center of its body is a red core, which sends mysterious radio signals into the night sky.
Interestingly Starmie's "back-half" has been depicted several different ways. In the anime Starmie has the appearance of two starfish fused together; while in more modern games the back-half has been shown to spin wildly completely independent of the front-half of the Pokémon. Many fans tend to think of the anime's depiction as the more realistic of the two considering the rapid spinning would obviously get in the way of a trainer trying to surf on this particular Pokémon. Starmie's core shines in a rainbow of seven colors, some people value this core as a type of jewellery.
In the anime, Misty owns both Starmie and a Staryu at the same time making it one of the extremely rare cases that trainer has both pre- and post-evolutions on their person at the same time. She later gave away Starmie to the Cerulean Gym to preform underwater shows, but kept her Staryu.
Despite being Genderless, it was able to learn egg moves in Gold and Silver. It was fixed in Crystal though.
Of these, Starmie is the only one that doesn't evolve and has no visible eyes throughout its evolutionary line (As Golbat - Zubat's evolution - and Hydreigon - Zweilous' evolution - have visible eyes).
Starmie's name, comes from the words "star" and Starmie sounds like "me", while its previous evolution, Staryu, sounds like "you".
