Abstract
In a shallow coastal region of Sardinia (European Mediterranean Sea) the activity pattern and migration habits of the sea star Astropecten aranciacus were studied by means of SCUBA diving. The species is nocturanl, 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.
