Cloyster, the Bivalve Pokémon, is a Water-type creature introduced in Generation I. It evolves from Shellder when exposed to a Water Stone, becoming a formidable Pokémon known for its incredibly tough shell and powerful defensive capabilities. Its shell, said to be harder than diamonds, can withstand almost any attack, and it closes tightly when threatened, leaving only its sharp horn exposed. Cloyster's natural habitat is deep ocean floors, where it remains motionless, waiting for prey. It ambushes its targets by opening its shell suddenly and then clamping down. In the anime, Cloyster often appears as a strong opponent, showcasing its defensive prowess and ice-based attacks. In the games, it's valued for its high Defense and Special Defense stats, making it a reliable wall. Its unique biology and imposing appearance have made it a memorable part of the Pokémon universe, representing the resilience and power of marine life.
