Azorean limpet
Common Name: Azorean limpet
Scientific Name: Patella ulyssiponensis aspera
Description: Locally known as “lapa brava” Patela aspera is one of the

two species of limpets collected for human consumption in the Azores. The taxonomical status has some uncertainly, but the most recent study (Hawkins et al. 2000) suggests that the Azorean species previously considered a subspecies, P. ulyssiponesis aspera, is in fact a valid and well differentiated endemic of the Macaronesia region. Its distribution in the OSPAR Maritime Area is limited to the islands of the Azores where it occurs on rocky substrates in the intertidal, and in the shallow sublittoral. (e.g. Christiaens, 1973; Titselaar, 51998).In the Azores this species is one, if not the most, important grazer in the superior subtidal, and is considered as keystone species on the rocky shore of the archipelago.
