Mediante buceo y exploraciones al intermareal y submareal de la región Áncash (9°58’08’’S 78°38’34’’W y 10°34’06’’S 77°54’30’’W) entre el 2003 y el 2010 se colectaron, identificaron y fotografiaron 135 especies de invertebrados que corresponden a los grupos Cnidaria (6 especies), Annelida (11 especies), Brachiopoda (1 especie), Mollusca (70 especies), Arthropoda (34 especies), Echinodermata (10 especies), Sipunculida (1 especie) y Chordata (2 especies). Del total de especies, se considera que Sipunculus (Austrosiphon) mundanus representa un nuevo registro para el Perú, que cuatro ampliaron su distribución hacia el norte y nueve hacia el sur. Cada especie se ubica taxonómicamente y se proporciona información de nombre común, diagnosis, hábitat, profundidad, aspectos bioecológicos, distribución geográfica, localidades en la región Áncash, otras localidades en el Perú, comentarios y referencias.
ABSTRACT: A total of 135 species of invertebrates of Cnidaria (6 species), Annelida (11 species), Brachiopoda (1 species), Mollusca (70 species), Arthropoda (34 species), Echinodermata (10 species), Sipunculida (1 species) and Chordata (2 species) were collected during intertidal and subtidal excursions along the coast of the Áncash Region, between 2003 and 2010. Taxonomic information and diagnosis, common names, habitat type, depth, ecological aspects, geographical distribution, distributional aspects, remarks and references are provided for each species. Sipunculus (Austrosiphon) mundanus is reported as a new record for Peru. Four species expanded its distributional range northward and nine species southward.
