Marine biogenic calcification is the production of calcium carbonate by organisms in the global ocean.. Marine biogenic calcification is the biologically mediated process by which marine organisms produce and deposit calcium carbonate minerals to form skeletal structures or hard tissues.
"Steamers" (steamed soft-shell clams) are an integral part of the New England clam bake, where they are served steamed whole in the shell, then pulled from the shell at the table, the neck skin is removed and then while holding the clam by the neck it is dipped, first in the clam broth in which they were cooked, to rinse away remaining sand ...
In statistical modeling, regression analysis is a set of statistical processes for estimating the relationships between a dependent variable (often called the outcome or response variable, or a label in machine learning parlance) and one or more error-free independent variables (often called regressors, predictors, covariates, explanatory ...
The mollusc (or mollusk [a]) shell is typically a calcareous exoskeleton which encloses, supports and protects the soft parts of an animal in the phylum Mollusca, which includes snails, clams, tusk shells, and several other classes. Not all shelled molluscs live in the sea; many live on the land and in freshwater.
Some pea clams (genus Pisidium) have an adult size of only 3 mm (0.12 in). In contrast, one of the largest species of freshwater bivalves is the swan mussel from the family Unionidae ; it can grow to a length of 20 cm (7.9 in), and usually lives in lakes or slow-flowing rivers.
There are both commercial and recreational harvests of chocolate clams. They are collected by hand on the beach at low tide, by free divers, and by scuba and hookah-equipped divers. The commercial harvest in Mexico grew from 125 metric tons in 1985, to 1,400 metric tons in 2006, and to 4,272 metric tons in 2014. [10]
Right after reaching maturity, these clams produce eggs, followed by sperm. Throughout adult life, Corbicula is a self-fertile simultaneous hermaphrodite which can broadcast spawn up to 570 mucoid larvae per day per individual, and more than 68,000 per year per individual. [19]
Corbicula is a genus of freshwater and brackish water clams, aquatic bivalve mollusks in the family Cyrenidae, the basket clams. [1] The genus name is the Neo-Latin diminutive of Latin corbis, a basket, referring to the shape and ribs of the shell.
