[[Category:{{{type1}}}-type Pokémon|{{{ndex}}}]] Cloyster (Japanese: パルシェン Parshen) is a dual-type Water/Ice Pokémon.

It evolves from Shellder via Water Stone.

Biology

Physiology

Cloyster has a spiky shell, which is used to protect its soft insides from foes. Its "head" and face resemble a black pearl.

Gender differences

None.

Special abilities

Cloyster has strong defenses and moderate offenses, both thanks to its sturdy shell. It fights by clamping its shell tightly shut while launching spikes from its shell to strike opponents.

Behavior

Cloyster is a clever and sneaky Pokémon, viciously rushing at prey shooting with spikes. It fights roughly because of the hostile nature of its habitat and the protection of its shell, allowing it to withstand physical blows easily.

Habitat

Cloyster lives deep under the sea, usually on the seabed or amongst coral and rocks.

Trivia

• Cloyster has the highest base Defense of any Generation I Pokémon at 180. It was surpassed in Generation II by Steelix (200) and Shuckle (230). Currently it is tied with Aggron for the 4th highest behind the two previously mentioned Pokémon, and Regirock (200).
• In Cloyster's Red and Blue sprite it opens up and down and not side to side.
• The color of Cloyster's head changed from Generation III to Generation IV. Its head was black until the generation shift, at which time it changed to purple.
• Cloyster would have the exact same cry as Fearow if it weren't for some pitch and loudness changes

Origin

It appears to be based off of a bivalve with a black pearl as its head.

Name origin

Cloyster's name may be a combination of cloister, to seclude or shelter oneself, and oyster. It could also be a combination of clam and oyster. Its Japanese name may be a combination of パール pearl and シェル shell.

In other languages

• German: Austos - From Auster (oyster).
• French: Crustabri - From crustacé (crustacean) and abri (shelter).
