[ES] Se exponen los resultados obtenidos a partir de los diferentes muestreos realizados en julio de 2002 en el suroeste de la costa portuguesa, en el ámbito de tres proyectos centrados en los moluscos opistobranquios. Se muestrearon dos áreas: una en los alrededores de Sagres (37° 00’ N, 8° 57’ O), en el extremo suroeste continental de Portugal y la otra en los alrededores de Sines (37° 57’ N, 8° 53’ O), a 110 km al norte de la primera. Se identificaron 81 especies de opistobranquios, seis de las cuales constituyen nuevas citas para la fau- na portuguesa.

Two areas were sampled, one around Sagres (37° 00′ N, 8° 57′ W) on the SW tip of the Portuguese mainland, the other near Sines (37° 57′ N, 8° 53′ W), 110 km north of the other site. Eighty-one species of opisthobranchs were identified, six of them new to the Portuguese fauna. © Instituto Español de Oceanografía, 2003.
