Descrição
Resumo:A study was conducted on the species Phymactis clematis Dana, 1849 (Anthozoa: Actiniaria) in the intertidal zone of Mar del Plata and Santa Clara del Mar (Province of Buenos Aires, Argentina). A great number of this species lives in protected microhabitats such as crevices, and tends to be larger than those in exposed areas. The specimens from the protected zones appear to have better environmental conditions, due to a greater concentration of oxygen and food in the remnant sea water during low tides. The dispersion of P. clematis is aggregated and the population density is variable. The highest values were recorded in Playa Punta Cantera (Mar del Plata) in comparison to Santa Clara del Mar.
