A dive at Cat Rock, Anacapa, on Sunday found large areas of the rocks covered by brittle stars. Indeed, the seabed could not be seen due to the mass of brittle stars and a simple grab with my hand yielded a dozen or more. I have heard previous reports of such gatherings but this was the first that I witnessed. Is there a name for such an event? Does anyone know the reasons for it or how often it happens?
