Species
There are more than 200 living species of cockles, with many more fossil forms.
The common cockle, Cerastoderma edule, is widely distributed around the coastlines of Northern Europe, with a range extending west to Ireland, the Barents Sea in the north, Norway in the east, and as far south as Senegal.
The dog cockle, Glycymeris glycymeris, has a similar range and habitat to the common cockle, but is unrelated. It is inedible due to its toughness when cooked, although a process is being developed to solve this.
The blood cockle, Anadara granosa (not related to the true cockles, instead in the family Arcidae) is extensively cultured from southern Korea to Malaysia.
An example group of true cockles that have shells which are completely smooth, without ribs, is the genus Laevicardium. These are often known as egg cockles.

Famous quotes containing the word species:
“If we consider the superiority of the human species, the size of its brain, its powers of thinking, language and organization, we can say this: were there the slightest possibility that another rival or superior species might appear, on earth or elsewhere, man would use every means at his disposal to destroy it.”
—Jean Baudrillard (b. 1929)
“Heaven and hell suppose two distinct species of men, the good and the bad. But the greatest part of mankind float betwixt vice and virtue.”
—David Hume (1711–1776)
“If there is a species which is more maltreated than children, then it must be their toys, which they handle in an incredibly off-hand manner.... Toys are thus the end point in that long chain in which all the conditions of despotic high-handedness are in play which enchain beings one to another, from one species to another—cruel divinities to their sacrificial victims, from masters to slaves, from adults to children, and from children to their objects.”
—Jean Baudrillard (b. 1929)
