Bat stars are a pacific invertebrate dwelling in waters that are typically cold. They are so named for the bat-like webbing that exists between their five to nine arms. They come in a wide array of colors from red to green. Bat stars can be solid coloured or mottled in appearance. When they reproduce, males and females release their gametes into the water, which are then carried out to sea where they unite. Bat stars are an important part of ocean ecosystems; as detritivores and scavengers, they eat and clear away dead algae and animals from the ocean floor.
