Title: Activity Pattern of the Sea‐Star, Marthasterias glacial is, in Port‐Cros Bay (France, Mediterranean Coast)
Abstract: Abstract. Tagged individuals of Marthasterias giacialis (L.) followed in situ for 24 h cycles or for up to 4 consecutive days show that sea‐star activity is not only nocturnal; we observed a non‐synchronized (between individuals) movement, with 1 or 2 (ocassionally 3) peaks; movement, occurs mainly between 6:00 p.m. and 9:00 a.m., without a clear peak at the population level, independent the prevailing light conditions (for 6:00–9:00p. m. and 6:00–9:00a. m. periods). M. giacialis shows periods of inactivity ranging from 1 to 3 days. It is hypothesized that the study site is visited for short term feeding raids by individuals coming from the deep water and then moving back.
