Resumo: This study evaluated the physiological, morphological and ethological effects of salinity variations on the tropical zoanthid Protopalythoa variabilis. This zoanthid was submitted to different salinity levels to probe the hypothesis of osmoregulation. Specimens collected in beach rocks from Northeastern Brazil were taken alive to the laboratory in their original water. The osmoregulatory ability of P. variabiliscan be determined by measuring the hemolymph osmolality under various salinity conditions and comparing with the osmolality of the medium. The zoanthid P. variabilis is a “weak regulator”, as it only osmoregulates within a narrow range of external salinity values, and its hemolymph osmolality drops, approximately in parallel with the isosmotic line, when the medium salinity falls below a certain limit. Ethological and morphological modifications under different salinities are discussed. This experiment shows for the first time the importance of osmotic regulation in the tropical zoanthid P. variabilis

This experiment shows for the first time the importance of osmotic regulation in the tropical zoanthid P. variabilisEste estudo avaliou os efeitos fisiológicos, morfológicos e etológicos no zoantídeo tropical Protopalythoa variabilis em diferentes níveis de salinidade. Para testar a hipótese de osmorregulação, o zoantídeo foi submetido a diferentes variações de salinidade. Os indivíduos foram coletados em recifes de arenito no Nordeste brasileiro e foram levados vivos para o laboratório na água em que foram recolhidos. A capacidade osmorregulatória de P. variabilis foi determinada pela medição da osmolaridade da hemolinfa em diferentes condições de salinidade e comparadas com a osmolaridade do meio. O zoantídeo P. variabilis é um “regulador fraco” visto que osmorregula dentro de uma estreita faixa de valores de salinidade externa e quando a salinidade do meio cai abaixo de um certo limite, ocorre redução da osmolaridade da hemolinfa, aproximadamente em paralelo com a linha isosmótica. As mudanças etológicas e morfológicas em diferentes salinidades são discutidas. Este experimento demonstra pela primeira vez a importância da regulação osmótica no zoantídeo tropical P. variabilis.Acta Scientiarum.
