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 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)
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.
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 ...
This species may be found prowling in prey-rich coral reefs, where its coloration allows it to blend in and its slim body enables it to hunt in tight places. [13] It inhabits a wide range of other habitats, [14] particularly sandy and muddy sediments, as well as around rocks and sponges. [13] It has been recorded at depths of up to 95 meters ...
Some species can grow more than two metres in length. [1] [2] They are blind but have a very good sense of smell, and eat decaying meat, fish and seaweeds that have washed to shore. [3] Originally identified as a single species in 1868 (Diopatra teres), in 1878 they were placed in the genus Onuphis. [4]
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.
Alitta succinea (known as the pile worm, clam worm or cinder worm) [3] is a species of marine annelid in the family Nereididae (commonly known as ragworms or sandworms). [4] It has been recorded throughout the North West Atlantic, as well as in the Gulf of Maine and South Africa .
