Nereididae
ragworms

It is classified as a polychaete in the family Nereididae .

Nereididae (formerly spelled Nereidae) are a family of polychaete worms.

Perinereis (Polychaeta, Nereididae) from Australia, with redescriptions of six additional species.

The prostomium of Nereididae bears a pair of palps that are differentiated into two units, the proximal unit is much larger than the distal unit.

Alitta succinea (known as the pile worm or clam worm) is a species of marine annelid in the family Nereididae (commonly known as ragworms or sandworms).

There is agreement on the monophyly of a group including the Hesionidae, Nereididae and Chrysopetalidae families but opinions differ about Pilargidae, and molecular and morphological studies continue.

Prey of Conus ebraeus include Perinereis helleri (family Nereididae), Palola sp., Eunice cariboea and Lysidice collaris (all three from family Eunicidae).

Namalycastis jaya Mathan Magesh, Kvist & Glasby, 2012 is a species of brackish-water polychaete worm in the family Nereididae known from the southern coast of Kerala in southwest India.

Its prey on Easter Island include: Eunicidae includes Lysidice collaris, Nematonereis unicornis, Eunice afra, Eunice cariboea and Palola siciliensis; Nereididae includes Perinereis singaporensis; Onuphidae includes Onuphis sp.

Ragworms' teeth are made of a very tough, yet lightweight material.

They may be commonly called ragworms or clam worms.

Like the ragworms, the catworms have separate sexes and all worms in the population breed on the same day.

Best method is float fished maggots, ragworms or bread.

Ragworms are considered a delicacy in Vietnam.

Ragworms' jaws are now being studied by engineers as they offer an exceptional combination of lightness and strength.

The sands are pretty busy these days, too: men digging for ragworms, dog-walkers, even one brave swimmer.

Ragworms are mainly omnivorous but many are active carnivores.

Ragworms such as Hediste diversicolor are commonly used as bait in sea angling.

It also eats fish and ragworms, scavenges for offal and sometimes follows fishing boats.

For example, a planned closed containment salmon fish farm in Scotland uses ragworms, algae and amino acids as feed.

Ragworms' jaws are strong but much lighter than the hard parts of many other organisms, which are biomineralized with calcium salts.

Alitta is a genus of marine annelids in Nereididae family (commonly known as sandworms or ragworms).

Ragworms are predominantly marine organisms that may occasionally swim upstream to rivers and even climb to land (for example Lycastopsis catarractarum).

Baits for this perch include minnows, or lugworms, and ragworms, shrimps, and artificial lures.

Not much is known about the biology of white ragworms Nephtys species and potential for mitigation of the impacts of collection of this genus.

Exploited and unexploited populations of king ragworms were studied for one year on the north-east coast of England by Blake (1979b).

Ragworms, Neridae Ragworms are quite widespread in more sheltered sediment areas.

In this area of salt marsh and mudflats live small marine animals such as mussels, periwinkles, lugworms, shrimps, and ragworms.

We will feed our fish on ­pellets made from ragworms, algae and amino acids instead of taking fish out of the sea to make fish meal.

In the Menai Strait very rich infaunal populations had previously been recorded in areas which were then intensively dug for king ragworms.

These constitute feed for shellfish and ragworms and, in turn, the ragworms are used as food for the sole.

Anyone who can provide shore fishermen with fresh and regular supplies of ragworms and other delicacies enjoyed by fish will make a steady profit from the foreshore.

Each square metre of this mud typically contains hundreds of thousands of invertebrates such as Hydrobia (a tiny snail), ragworms and bivalves.

It has been estimated that one square metre of mud may contain up to 60,000 Laver Spire Snails or thousands of Ragworms.
