Halityle regularis, commonly known as the mosaic cushion star, [2] is a species of sea star in the family Oreasteridae. It is the sole species in the genus Halityle. [1]
The mosaic cushion star is found in the Western Central Pacific in countries such as the Philippines. [3] [4] It is found in tropical climates in depths of 3–90 meters. [2] [3]
Starfish or sea stars are star-shaped echinoderms belonging to the class Asteroidea. Common usage frequently finds these names being also applied to ophiuroids, which are correctly referred to as brittle stars or basket stars. Starfish are also known as asteroids due to being in the class Asteroidea. About 1,900 species of starfish occur on the seabed in all the world's oceans, from warm, tropical zones to frigid, polar regions. They are found from the intertidal zone down to abyssal depths, at 6,000 m (20,000 ft) below the surface.
The Valvatida are an order of starfish in the class Asteroidea, which contains 695 species in 172 genera in 17 families.
