Marine Ecology, 1996
Abstract.A survey of the historical background of chemically boring bivalves and the proposed methods of boring, indications for biocorrosion, observations, and experimental results are provided. The regional impact to the ecosystem is discussed with examples from the N. Adriatic, Caribbean, and E. Pacific.

A new benthic species of the protobranch bivalve genus Solemya , from the northeastern Pacific Ocean, lacks a gut. It has no internal digestive enzymatic apparatus; nor is there any provision for the secretion of enzymes into the mantle cavity for extraorganismic digestion.

Bivalves are comprised of animals unclosed in two shell valves, such as mussels oysters, scallops and clams. There are about 7,500 bivalve species and some ofthem are of commercial importance. Recently, interest in bivalve immunity has increased due to the importance in worldwide aquaculture and their role in aquatic environmental science and their ...

Exceptionally well preserved larval bivalve shells have been isolated from Late Cretaceous (Maestrichtian) sediments. Specimens were readily identified to familial level on the basis of gross morphology and hinge structures. Reconstruction of fossil larval ontogeny, linked with the distribution of adult stages, will provide an important interpretative ...

The subclass Protobranchia comprises more than 600 species of bivalves that occur throughout the world ocean. Mostly deposit feeders in soft sediments, they are abundant in the deep sea. Apomorphies that unite them as a group include gill structure, hinge conformation, shell microstructure, larval development, foot morphology, respiratory pigments ...

The epidemiological data clearly demonstrates that filter feeding bivalve shellfish can, and do, act as efficient vehicles for the transmission of enteric viruses transmitted by the faecal-oral route. This identified hazard has been documented as a cause for concern by various international agencies and has a long history.

The catalase of a freshwater bivalve
Canadian Journal of Zoology, 1970The catalase activity of various tissues of a freshwater mussel was studied. The concentration in the digestive gland is about three times that of the viscera and seven times that of mantle and muscular tissue. Semipurified digestive gland catalase has optimal activity at 10 °C and pH 7.8.
