Starfish: Anatomy, Life cycle & Ecology

Starfish or sea stars are a class of echinoderms generally shaped like a star polygon. (In common usage, these names are also often applied to ophiuroids, which are correctly referred to as brittle stars or basket stars.) Starfish are also known as asteroids because they form the taxonomic class Asteroidea (/ˌæstəˈrɔɪdiə/). About 1,900 species of…
