Benthopectinidae

Benthopectinidae is a family of sea stars containing at least 75 species in eight genera. It is the only family in the monotypic order Notomyotida.

These asteroids are deep-sea dwelling and have flexible arms. The inner dorso-lateral surface of the arms contain characteristic longitudinal muscle bands. 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.
