Appearance
Bat stars can be many different types of colors. The bat star breathes through gill-like structures on its back that perform as respirators. It lacks the pincers or pedicellariae that most starfish use to clean the skin surface of debris, but its small, moving hairs or cilia may create enough of a water current to keep the surface of its skin clean. It has visual sensors at the end of each ray that can detect light and note prey. To eat its prey, it covers the prey with its stomach and oozes digestive juices over it; this liquefies the food, enabling the bat star to ingest it. It is omnivorous, eating both plants and animals alive or dead.Behavior
Bat stars may gently "fight" with each other if they meet. Fighting behavior consists of pushing and laying an arm over the other.Bat stars are important as detritivores and scavengers, collecting algae and dead animals from the ocean floor.
Reproduction
The bat stars reproduce through spawning. The male casts sperm and the female drops eggs; each has pores at the base of the rays for this purpose. The sperm and egg unite at sea and are carried away by ocean currents.References:
