Contribució al coneixement de la distribució ecològica dels picnogònides a la Costa Brava catalana

An ecological and faunistic study on the Pycnogonida ocurring on Halopteris and Posidonia substrates of the Catalan Costa Brava has been carried out. The present work provides new data for seven rare species in the Mediterranean sea and new citations of Nymphon gracile and Ammothella biunguiculata from the oriental spanish coast. Also included are data about presence and abundance of the species, related with depth, substrate and water movement
