The Oreasteridae are a family of sea stars in the class Asteroidea.

Description and characteristics

This family contains many species of regular starfishes with usually 5 arms around a stiff, convex and often brightly colored body. Whereas some species are very easy to identify, like the "pincushion seastars" (Culcita sp.), some other can be difficult to tell apart.^[2]
