Sinonovacula constricta, the constricted tagelus, Chinese razor clam or Agemaki clam, is a commercially important species of bivalve native to the estuaries and mudflats of China and Japan. It is extensively aquafarmed in China and other countries, with 742,084 tons worth US$667,876,000 harvested in 2008.
Harvesters should check current public health recommendations by marine authorities before collecting razor clams. In the United States, razor clam harvesting is typically authorized by state officials several times a year. [7] Harvesters locate the clam by looking for a "show," which can present as either a hole or depression in the sand. [8]
[6]: 10 Its range covers the Indo-Pacific, but populations are diminishing quickly and the giant clam has become extinct in many areas where it was once common. [5] The maxima clam has the largest geographical distribution among giant clam species; it may be found off high- or low-elevation islands, in lagoons or fringing reefs. [7]
The pod razor (Ensis siliqua) is a coastal bivalve of European waters. It is edible and has been fished commercially, especially in Portugal, Spain, Ireland and Scotland. [3] Ensis siliqua is also known as the razor fish, razor clam or giant razor. There is at least one subspecies: E. s. minor. [4]
The creature in the video is a Pacific razor clam, though it looks enough like a geoduck to befuddle even a knowledgeable biologist: Digging into wet sand is a survival technique for the critter ...
The shell of the clam ranges from 15 centimetres (6 in) to over 20 centimetres (8 in) in length, but the extremely long siphons make the clam itself much longer than this: the "shaft" or siphons alone can be 1 metre (3 ft 3 in) in length. The geoduck is the largest burrowing clam in the world. [3]
By day, the clams spread out their mantle so that the algae receive the sunlight they need to photosynthesize, whereas the colour pigments protect the clam against excessive light and UV radiation. Adult clams can get most (70–100%) of their nutrients from the algae and the rest from filter feeding. [12] When disturbed, the clam closes its shell.
This subfamily contains the largest living bivalve species, including Tridacna gigas, the giant clam. They have heavy shells, fluted with 4–6 folds. They have heavy shells, fluted with 4–6 folds. The mantle is usually brightly colored.
