Alitta virens (common names include sandworm, sea worm, and king ragworm; older scientific names, including Nereis virens, are still frequently used) is an annelid worm that burrows in wet sand and mud. They construct burrows of different shapes (I,U,J and Y) [2] They range from being very complex to very simple. Long term burrows are held ...
The blow lugworm (Arenicola marina), also known as sandworm, is a large species of marine worm. Its coiled castings are a familiar sight on a beach at low tide but the animal itself is rarely seen except by those who, from curiosity or to use as fishing bait , dig the worm out of the sand.
The following species are recognised in the genus Arenicola: [2] Arenicola brasiliensis Nonato, 1958; Arenicola cristata Stimpson, 1856; Arenicola defodiens Cadman & Nelson-Smith, 1993; Arenicola glasselli Berkeley & Berkeley, 1939; Arenicola loveni Kinberg, 1866; Arenicola marina (Linnaeus, 1758)
More than 10,000 species are described in this class. Common representatives include the lugworm ( Arenicola marina ) and the sandworm or clam worm Alitta . Polychaetes as a class are robust and widespread, with species that live in the coldest ocean temperatures of the abyssal plain , to forms which tolerate the extremely high temperatures ...
Urechis unicinctus, known as the fat innkeeper worm or penis fish, [3] [4] is a species of marine spoon worm in East Asia. It is found in Bohai Gulf of China and off the Korean and Hokkaido coasts. [4] It is not to be confused with a closely related species, Urechis caupo, which occurs on the western coast of North America and shares common ...
Eunice aphroditois is a benthic bristle worm of warm marine waters. It lives mainly in the Atlantic Ocean, but can also be found in the Indo-Pacific. [1] [2] It ranges in length from less than 10 cm (4 in) to 3 m (10 ft). [3]
Members of this family live in tubes made of sand and shell fragments cemented together and attached to rocks. Some species are colonial and the multitude of their tubes may create hummocks and even reefs. The top of the tube can be closed by an operculum formed by several rings of bristles on the head of the worm.
The species is collected and sold as a model organism for various fields of science, as fish bait, or for human consumption. It is also sold and exported as a dried seafood product. In particular, S. nudus is collected, cleaned of its innards, and eaten as a delicacy in the South Chinese provinces of Guangdong, Hainan, Guangxi, and Fujian.
