Alitta virens (common names include sandworm and king ragworm; older scientific names including Nereis virens are still frequently used) is an annelid worm that burrows in wet sand and mud. It is classified as a polychaete in the family Nereididae [1].

Sandworms make up a large part of the live sea-bait industry.To fulfill in the needs of this industry, sandworms are also grown commercially.[2] "Sandworming", or the harvesting of sandworms from mudflats, employs over 1,000 people in Maine. As of 2006, the population of sandworms had diminished greatly over the preceding few years due in large part to overharvesting before the worms are able to reproduce by spawning.

Sandworms eat seaweed and microorganisms. They have many distinctive traits, including

The parapodia function both as external gills (the animal's primary respiratory surfaces), and as means of locomotion (appearing much like short legs).
