The Sand Sea Star, also known as the Sand Sifting Sea Star or Starry Sand Dollar, is a species of sea star that is commonly found in the shallow sandy areas of the Indo-Pacific region, from East Africa to the Central Pacific Ocean. As its name suggests, the Sand Sea Star is well adapted to life on the sand and has a flattened body with long, pointed arms that help it move over the sandy substrate. The Sand Sea Star is a detritivore and feeds primarily on organic matter and small invertebrates that it finds on the sandy bottom. It is an important part of the reef ecosystem as it helps to keep the sand clean and free of debris, allowing other organisms to thrive. The Sand Sea Star is relatively hardy and easy to care for in the home aquarium, but it requires a sand substrate and a moderate water flow to keep it healthy. It is generally peaceful and can be kept with other invertebrates and small fish, but it may prey on small sand-dwelling organisms like worms and small crustaceans.
