Solemyidae
Solemyidae is a family (biology), family of saltwater clams, marine (ocean), marine protobranch bivalve mollusks in the order (biology), order Solemyida. Biology Solemyids are remarkable in that their digestive tract is either extremely small or non-existent, and their feeding appendages are too short to reach outside the shell. It has been shown that these clams host sulphur-oxidizing bacteria intracellularly within their gill filaments. As chemoautotrophs, these bacterial symbionts synthesize organic matter from CO2 and are the primary source of nutrition for the whole organism. In turn, the animal host provides its symbionts a habitat in which they have access to the substrates of chemoautotrophy (O2, CO2, and reduced inorganic compounds such as H2S). Together, these partners create "animals" with novel metabolic capabilities. Genera and species The family Solemyidae includes two genera and the following species: * ''Acharax'' W. H. Dall, Dall, 1908 ** ''Acharax alinae'' M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solemya Borealis
''Solemya borealis'' , the boreal awning clam, is a species of saltwater clam, a Marine (ocean), marine bivalve mollusc in the family (biology), family Solemyidae the awning clams. This species is found along the northeastern coast of North America, from Nova Scotia to Connecticut. S. borealis belong to the Petrasma subgenus; being characterized by having an elongated oval shell with parallel ventral and dorsal margins. Individuals may reach a length of 8 to 10 cm and have a periostracum of dark brown color. Nutritionally, S. borealis contains concentrations of Chemotroph, chemoautotrophic bacteria in inner gill filaments, Symbiosis, symbiotically attached to the host.Conway, N.M., Howes, B.L., McDowell Capuzzo, J.E.
