Tal como os demais anelídeos, são invertebrados com corpo segmentado e simetria já citado, em Nereidiformia, os indivíduos apresentam prostômio e peristômio distintos e os Hesionidae, com seus corpos muitas vezes de cores vibrantes , não são uma constituírem um grupo muito diverso entre si, apresentam diversos padrões morfológicos como veremos a seguir. 1. 1. Nereis virens is a large and common estuarine and coastal nereid polychaete of the North Atlantic Ocean, frequently used in physiological experiments.. 2. 2. N. virens is euryhaline, surviving from about 5% o (15% SW) to over % SW.. 3. 3. N. virens is slightly hyperosmotic at all salinities, with a modest increment in coelomic fluid hyperosmoticity when adapted to salinities below .
Segmented: The most common marine worms belong to the phylum Annelida. They are distinguished by the little rings or segments that make up their bodies. The most common marine annelids are the polychaetes. Polychaetes can be divided into two categories: errant and sedentary. Errant polychaetes worms are free swimming predators. This paper reviews the alien polychaete species in the world's oceans and their impacts on the marine ecosystems and humans. A total of polychaete species belonging to genera and 39 families have been transported around the world's oceans with human-mediated assistance.

[Marian H Pettibone; United States National Museum.; Smithsonian Institution.] -- The polychaetes of the Atlantic coast of New England are still imperfectly known. The present study attempts to give as complete a representation of the New England polychaete fauna as is now.

Moore's interest in the polychaetes was diverse. He identified the polychaetes. The Polychaeta / ˌpɒlɪˈkiːtə /, also known as the bristle worms or polychaetes, are a paraphyletic class of annelid worms, generally marine.
Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called chaetae, which are made of chitin. As such, polychaetes are sometimes referred to as bristle worms.
Polychaetes are well represented in most marine and estuarine environments, both in terms of number of individuals and species, and they typically contribute a significant percentage of the total macrofaunal diversity.
They exhibit considerable variations in recruitment in both time and space, which is then often reflected in adult distributions. Exposed to the water, the scientists saw that the hydrate was crawling with tiny worms —a new species (Hesiocaeca methanicola) of polychaete.

Gov't Print. Off. Polychaetes of the family Syllidae exhibit a remarkable diversity of reproductive phenomena. The primitive mode of sexual reproduction is characterized by epitoky (as epigamy and stolonization, respectively), swarming and external fertilization.
Deviations from the primitive type, particularly evident in meiofaunal species, include external brooding, direct sperm transfer, internal.
Gravid worms show a peculiar method of swimming in which the anterior region is held rigid. A pair of flagellar vanes and other features characterize the fine structure of the spermatozoon. The mature oocytes bear microvilli, and some express a jelly-like layer after fertilization which traps excess spermatozoa.

Such residue-effects information was generated for the marine polychaete worm, Neanthes arenaceodentata, exposed to the organometal, tributyltin (TBT). Juvenile Neanthes were exposed in the laboratory to five concentrations (,50, 10, 0 ng l) of TBT.
