In this dive of 09/04/2016 we think we have documented reproduction of Stella Gorgone or Astrospartus mediterraneus, the remarkable view of the amount of specimens in an area so circumscribed, little is known about its reproduction, has separate sexes but without sexual dimorphism. From the photos, however, it seems clear that it has documented an incident all the more rare and poorly documented at the time.

“Only Mediterranean representative of Gorgonocefalidi family, this brittlestar has a main body, polygon, from which branch arms, highly branched, completely covered with granules. The color is gray with lighter ramifications. The arms can reach 40 cm in length, while the body has a maximum diameter of 8 cm. Habitat: It is quite rare and lives at depths greater than 40 m throughout the Mediterranean. They may even find yourself on sandy and loamy. Power: Predator, feeds on small organisms. Reproduction: Little known, has separate sexes but without sexual dimorphism. Habits: usually tangled lives at sea fans.”
