| The tip of the South American cone is one of the most interesting Subantarctic areas, both biogeographically and ecologically. Nonetheless, knowledge of the area's biodiversity, in particular that of the subtidal marine habitats, remains poor. Therefore, in 2004, a biodiversity research project was carried out as a part of the cruise Cimar-10 Fjords, organized and supported by the Chilean National Oceanographic Committee (CONA). The results of the subtidal marine mollusk surveys are presented herein. The samples were collected aboard the Agor 60 "Vidal Gormaz" in winter 2004. The study area covered the northern Chilean Patagonia from Seno de Relocanví (41°31'S) to Boca del Guafo (43°49'S), on the continental shelf from 22 to 353 m depth. The Mollusca were... |

| After introductory remarks on the solitary coral genera Heterocyathus and Heteropsammia, commonly known to be symbiotic with a sipunculan inhabiting a gastropod shell, Heterocyathus japonicus is redescribed in detail. It occurs from Taiwan to northern Honshu, Japan. It is the first of these symbiotic corals to be found in association with an alternative partner, living specimens of the large scaphopod Fissidentalium vernedei. The coral always occupies the apical end of the shell, the part that protrudes from the sediment. It is thus preserved from being buried and is maintained in an upright position (the same advantages it also gets when its partner is a sipunculan). On live F. vernedei, H. japonicus incrusts a manganese rich black mineral coating that... |

| This study deals with detailed morphology and anatomy of 4 species of Scaphopoda and 5 species of protobranch Bivalvia. Both classes are traditionally grouped in the taxon Diasoma, which has been questioned by different methodologies, such as molecular and developmental. This study is developed under a phylogenetic methodology with the main concern in performing it in an intelligible and testable methodology. The analyzed Scaphopoda species came from the Brazilian coast and belong to the family Dentaliidae [(1) Coccodentalium carduus; (2) Paradentalium disparile] and Gadiliidae; [(3) Polyschides noronhensis, n. sp. from Fernando de Noronha Archipelago; (4) Gadila braziliensis]. These species represent the main branches of the class Scaphopoda. From... |
