Starmie

Starmie (Japanese: スターミー Sutaamii) is a /-type Pokémon introduced in Generation I.

Physiology
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 any 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.

Evolution
Starmie evolves from Staryu with the use of a Water Stone.

Anime
In the anime, Misty owns both Starmie and a Staryu at the same time, making it one of the extremely rare cases that a 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.

Trivia

 * Starmie is one of the five Pokémon that has no visible eyes. The others are Staryu, Zubat, Deino, and Zweilous.
 * Of these, Starmie is the only one that doesn't evolve further and has no visible eyes throughout its evolutionary line (as Golbat and Hydreigon have visible eyes).

Etymology
Starmie's name, comes from the words "star" and Starmie sounds like "me", while its previous evolution, Staryu, sounds like "you".
