Abstract

On an intertidal mud flat in the Ria Formosa (southern Portugal) Abra ovata (Mollusca: Bivalvia) showed effective meiobenthic and macrobenthic dispersal (i.e. of individuals smaller and larger than 1 mm). This was important to compensate for mortality caused by shore crabs during summer. It was observed in the laboratory that A. ovata deposited eggs in capsules on the sediment surface; after 11–15 d at 20°C benthic juveniles of 210–220 (im shell length hatched from these capsules. A pelagic larval stage was missing. Large numbers of specimens of about 1 mm shell length colonized protected buckets between February and June.
