It is renowned for its hard, protective shell which it uses to defend itself from predators. Shellder's diet primarily consists of plankton and other small marine organisms, which it filters from the water. Its behavior is largely characterized by its defensive nature, snapping its shell shut at the slightest provocation. It evolves into Cloyster when exposed to a Water Stone, gaining even greater defensive capabilities. In the games, Shellder often appears in coastal and underwater areas, serving as a common early-game Water-type. Its type matchups make it strong against Fire, Ground, and Rock types, while being weak to Grass and Electric types. Shellder has made numerous appearances in the Pokémon anime, often depicted as a somewhat mischievous or shy Pokémon, and has a memorable role in the anime for its evolution into Cloyster. Culturally, Shellder embodies themes of resilience and protection, reflecting its unique biology as a bivalve.
