Also known as Sea star, Asteroidea, Seastars, Blood star, Sea stars, Star fish, Seastar, starfishes

Starfish or sea stars are a class of marine invertebrates 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 (). About 1,900 species of starfish live on the seabed, and are found in all the world's oceans, from warm, tropical zones to frigid, polar regions. They can occur from the intertidal zone down to abyssal depths, at below the surface.

OverviewAI-generated

Starfish, also known as sea stars, belong to the class Asteroidea within the phylum Echinodermata. This group was established by de Blainville in 1830. The organisms inhabit marine environments.

Specific species within this classification include the Durban Crowfoot, which is categorized as a species. Records from iNaturalist indicate 11,643 observations
