Cloyster

() is a /-type Pokémon introduced in Generation I. 
==Biology==
===Physiology===
Cloyster is actually a black pearl within two shells. The first shell is purple and rugged, while the second shell is gray. When the second shell is opened, a spike is revealed. Its face has a cruel look upon it.
===Behavior===
To catch food, Cloyster wait on the ocean floor for prey swim by before shooting these spikes by using the move Spike Cannon. The harpooned prey then slowly float down to the waiting Cloyster. Like Shellder, Cloyster love Slowpoke tails, and may even venture onto land to seek them out. Cloyster are capable of swimming by swallowing water and jetting it out—this is the same process they use to shoot spikes. They can slam their shells shut with incredible force. Unlike Shellder, Cloyster can use clamping as a viable method of defense. Their insides are virtually untouchable while their shells are closed. Even the strongest forces cannot pry a clamped Cloyster apart; consequently, no one knows exactly what lies within their shells. It has been recently discovered that Cloyster that live in stronger currents have larger spikes, though the reason behind this is unknown. A concurrent study found that when a Cloyster shell is damaged, a new spike grows in place of the damaged area instead of recovering the flat surface.
===Natural abilities===
Cloyster's shell is extremely solid. It fights by keeping its shell tightly shut for protection, and by shooting spikes to repel foes.
==Evolution==
Cloyster is the evolved form of Shellder by use of a Water Stone.

Cloyster comes from clamp, clam and oyster. It is also a play on the word cloister (to protect onerself).
