✦ Synopsis

In a shallow coastal region of Sardinia (European MediVerranean Sea) the activity pattern and migration habit~ of the sea star Astropecten aranciacu2 were studied by means of SCUBA diving. The species is nocturnal, with two modes of abundance. Different size classes revealed different activity schedules. A sample taken at dusk consisted of comparatively large-sized sea stars, while another sample taken at night included small-sized sea stars with the larger individuals. By tagging the sea stars with numbers, their locomotory activity during the night, as well as day, was investigated.
