The Sandy Starfish is a type of marine animal found in shallow coastal waters. It belongs to the class Asteroidea and is known for its distinctive star shape, typically featuring five arms. These starfish have a tough, spiny skin that helps protect them from predators and can vary in color, often blending with sandy ocean floors. Sandy starfish are important to their ecosystems as they feed on small invertebrates, such as mollusks and barnacles. They use their tube feet, which operate through a water vascular system, to move and capture prey. Their ability to regenerate lost arms also makes them unique among marine creatures.
