Bivalves Antárticos e Subantárticos coletados durante as Expedições Científicas Brasileiras à Antártica I a IX (1982-1991)
Provedor de dados: 104
Autores: Narchi,Walter; Domaneschi,Osmar; Passos,Flávio Dias.
The bivalves collected in the Western Antarctic and Subantarctic waters by scientists of the Instituto Oceanográfico - USP during the Scientific Brazilian Expeditions to Antarctical-IX are characterised through its conchiliological features, illustrated and their occurrence plotted in maps. A species of bivalve collected by scuba divers of the IO-USP on the Napier Rock, Admiralty Bay, King George Island during the Expeditions XV and XVI is also considered in this work. The material identified is representative of 25 species distributed among three families and four genera of Protobranchia, three farnilies and five genera of Pteriornorpha, five families and six genera of Heterodonta, and four families and four genera of Anomalo desmata. The main scope of...

Anatomia funcional de Protothaca (Leukoma) pectorina (Lamarck) (Bivalvia, Veneridae)
Provedor de dados: 104
Autores: Guerón,Cordélia de Oliveira Castro; Narchi,Walter.
Protothaca (Leukoma) pectorina (Lamarck, 1818) lives from the West Indies to Santa Catarina State, Brazil, in soft muddy beaches in quiet waters of protected bays with little amounts of suspended material. A study of the functional anatomy of P. pectorina and its ecological aspects were undertaken. The anatomy and functioning of the stomach and the mechanisms for selection of particles were observed. The siphons, ctenidia, labial palps and stomach were analised and related to the animal's natural environment. The siphons belong to type B (Yonge 1948), the ctenidia to type C (1a) (Atkins 1937). The ctenidia are homorhabdic (Ridewood 1903) and the stomach belongs to type V (Purchon 1960).

Anatomia funcional de Perna perna (Linné) (bivalvia, Mytilidae)
Provedor de dados: 104
Autores: Narchi,Walter; Galvão-Bueno,Mario Sérgio.
Perna perna (Linné, 1758) occurs on the Atlantic littoral from Venezuela to Uruguay. The main organ systems were studied in the living animais, particular attention being paid to the ciliary feeding and cleansing mechanisms in the mantle cavity. The anatomy, functioning of the stomach and the ciliary sorting mechanisms are described. The siphons belong to type A (Yongf. 1948b), the ctenidia to type B( 1) (Atkins 1936c) and the stomach is of type III (Purchon 1957) or Section I (Dinamani 1967) with sorting mecanisms of type A and B (Reid 1965). A general comparison was made between the genera of the Mytilidae known and some features of Mytella Soot-Ryen, 1955.
