It typically has five arms, with the center disk of the animal being much wider than the stubby arms are in length. Although the bat star usually has five arms, it sometimes has as many as nine. Bat stars occur in many of colors, including green, purple, red, orange, yellow and brown, either mottled or solid. The bat star gets its name from the webbing between its arms,
Asexual reproduction in starfish generate new individuals in this way. He thought the arms might be shed by autotomy. In the same year, Monks showed experimentally that the "comets" developing from the severed arms of "Linckia columbiae" could indeed grow into new individuals. "Linckia multifora" and "Linckia guildingi" are two species of starfish found on Hawaii which were found to exhibit autotomy, shedding one or more arms frequently. The arms are known as "comets" and can move about independently and each one can grow into a new individual. Though severed from the nervous system and the water vascular system they still exhibit normal behaviour
