Nemertea is a phylum of animals also known as ribbon worms or proboscis worms, consisting of about 1300 known species. [2][3] Most ribbon worms are very slim, usually only a few millimeters wide, although a few have relatively short but wide bodies.

2018年3月20日 · Ne­merteans are found world-wide. The ma­jor­ity of species in this phy­lum are ma­rine, ben­thic, or lit­toral an­i­mals, known from in­ter­tidal to deep sea en­vi­ron­ments. A few are ter­res­trial or ec­topar­a­sitic (mainly species in sub­or­der Mono­stil­if­era), and around 20 species are found in fresh­wa­ter en­vi­ron­ments.

2024年10月3日 · Ribbon worms, also called nemerteans, are usually slim, vermiform invertebrates that constitute the phylum Nemertea. They are characterized by an eversible infolding of the body wall, the proboscis, lying in a coelomic cavity just above the gut.

2025年1月30日 · Species of the phylum Nemertea, or ribbonworms, inhabit all parts of the world's oceans, as well as many freshwater and terrestrial habitats. They are unsegmented worms characterized by a unique and remarkable eversible proboscis used for prey capture and sometimes locomotion.

ribbon worm, any member of the invertebrate phylum Nemertea (sometimes called Nemertinea, or Rhynchocoela), which includes mainly free-living forms but also a few parasites of crustaceans, mollusks, and sea squirts.

Nemertea is a phylum of largely aquatic invertebrate animals also known as ribbon worms or proboscis worms and characterized by long, thin, unsegmented body that is flattened posteriorly and cylindrical anteriorly and has a long retractable proboscis that can evert for such purposes as capturing prey, defense, and locomotion.

Nemertea is a phylum of invertebrates living in marine and freshwater waters worldwide that use their muscular proboscis to capture their prey.

The Nemertea are colloquially known as ribbon worms. Most species of phylum Nemertea are marine, predominantly benthic or bottom dwellers, with an estimated 900 species known.

Nemertea is a phylum of invertebrate animals also known as ribbon worms or proboscis worms. [1] Most of the 1,400 or so species are marine, with a few living in fresh water and a small number of terrestrial forms. They live in all marine habitats, and throughout the world's oceans. [2]

Nemertea is a phylum of invertebrate animals also known as 'ribbon worms' or 'proboscis worms'. Alternative names for the phylum have included Nemertini, Nemertinea and Rhynchocoela. Although most are less than 20 centimetres (7.9 in) long, …
