The tail shaft, 2 to 3 in (5.1 to 7.6 cm) from it, is marked by a highly coiled cast of sand. The lugworm lies in this burrow with its head at the base of the head shaft, swallowing sand from time to time. This makes the columns of sand drop slightly, so there is a periodic sinking of the sand in the saucer-shaped depression.
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 worms live in tubes made of sand and are filter feeders and ... The top of the tube can be closed by an operculum formed by several rings of bristles on the ...
They live underground and burrow in sand and soil — much like the gigantic sandworms in the action movie “Dune" — making them difficult to observe in their natural habitats.
Eunice aphroditois is also known as the bobbit worm [6] [7] or bobbitt worm. [8] The name is believed to be taken from the John and Lorena Bobbitt case, [9] but another possible reason for the name is the worm's jaw. It is sometimes called the sand striker [8] or trap-jaw worm. Traces of their burrows have been found among fossils near Taiwan ...
Lanice conchilega, commonly known as the sand mason worm, is a species of burrowing marine polychaete worm. It builds a characteristic tube which projects from the seabed, consisting of cemented sand grains and shell fragments with a fringe at the top. Polychaetes, or marine bristle worms, have elongated bodies divided into many segments.
Arenicolidae is a family of marine polychaete worms. They are commonly known as lugworms and the little coils of sand they produce are commonly seen on the beach. Arenicolids are found worldwide, mostly living in burrows in sandy substrates.
Abarenicola pacifica or the Pacific lugworm is a large species of polychaete worm found on the west coast of North America and also in Japan. The worms live out of sight in burrows under the sand and produce casts which are visible on the surface. Polychaetes, or marine bristle worms, have elongated bodies divided into many segments.
