Detailed explanation-1: -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 was first described by biologist Michael Sars in 1835. It is classified as a polychaete in the family Nereididae.

Detailed explanation-2: -The sandworms in Dune are giant animal worms known by their indigenous name as “Shai-Hulud.” To the Fremen, the deep desert dwellers of Arrakis, Shai-Hulud is considered a quasi-diety and sometimes called “Old Man of the Desert.” (When you see the new film, this last designation is important in one particular scene.)

Detailed explanation-3: -The lugworm or sandworm (Arenicola marina) is a large marine worm of the phylum Annelida. 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.

Detailed explanation-4: -Sandworms are colossal, worm-like creatures that live on the desert planet Arrakis. The sandworms’ larvae produce a drug called melange (known colloquially as “the spice"), the most essential and valuable commodity in the universe because it makes safe and accurate interstellar travel possible.

Detailed explanation-5: -These worms are annelids and made up of many segments bearing bristles called setae. They use these setae to swim. Sandworms in Maine and New England are harvested for fishing bait in mid-Atlantic markets. Diggers can get as many as 2000 worms in one full tide of harvesting and make a great days pay for this work.
