These asteroids are deep-sea dwelling and have flexible arms. The inner dorso-lateral surface of the arms contain characteristic longitudinal muscle bands.[2] Eight genera of deep-water species make up the majority of the family benthopectinidae, and many of its members are expected to have a greater range than is currently recognized.[3]
