Scaleworm
Polynoidae is a family of marine Polychaete worms known as "scale worms" due to the scale-like elytra on the dorsal surface. Almost 900 species are currently recognised belonging to 9 subfamilies and 167 genera. They are active hunters, but generally dwell in protected environments such as under stones. The group is widely distributed from shallow intertidal waters to hadal trenches. They are the most diverse group of polychaetes in terms of genus number and second most diverse in terms of species number which is almost 8% of all segmented worm species. Description Most Polynoidae species are short and flattened, but can reach as much as 20 cm in length and 10 cm width in ''Eulagisca gigantea'' and ''Eulagisca uschakovi''. Individuals are usually covered almost entirely by elytra, which can be shed and regenerated in many species. The elytra of some species are faintly bioluminescent, and leave glowing traces around the mouthparts of their predators, making those preda ...

Lepidonotus
''Lepidonotus'' is a genus of marine annelids in the family Polynoidae (scale worms). The genus occurs globally and includes 80 species, usually found in shallow waters down to about 80 metres. Description Body dorsoventrally flattened, short, with 26 segments and 12 pairs of elytra on segments 2, 4, 5, 7, 9, 11, 13, 15, 17, 19, 21, and 23. Prostomium with three antennae; lateral antennae continuous with prostomium, laterally to median antenna. Parapodia with elongate acicular lobes with both acicula penetrating epidermis. Notochaetae slender and densely serrated. Neurochaetae A chaeta or cheta (from Greek χαίτη “crest, mane, flowing hair"; plural: chaetae) is a chitinous bristle or seta found in annelid worms, (although the term is also frequently used to describe similar structures in other invertebrates such ... much more stout, with rows of spines distally and unidentate and/or bidentate tips (see Barnich & Fiege, 2003 for detailed diagnosis) .

Acholoe (animal)
''Acholoe squamosa'' is a species in the family Polynoidae (scale worms) and the only species in the genus ''Acholoe''; it occurs in the Mediterranean Sea and North-east Atlantic Ocean. Description Body long, with numerous segments (50 to more than 100) and numerous pairs of elytra on segments 2, 4, 5, then on alternate segments to 23 and on every third segment thereafter. The prostomium is anteriorly rounded (without peaks) and the lateral antennae are inserted terminoventrally. Parapodia with elongate acicular lobes with both acicula penetrating epidermis. The notochaetae are stout, with distinct rows of spines and blunt tips; the neurochaetae A chaeta or cheta (from Greek χαίτη “crest, mane, flowing hair"; plural: chaetae) is a chitinous bristle or seta found in annelid worms, (although the term is also frequently used to describe similar structures in other invertebrates such ... are unidentate (lack a secondary tooth at the tips) (see Barnich & Fiege, 2003 f ...

Augenerilepidonotus
''Augenerilepidonotus dictyolepis'' is a species of marine annelids in the family Polynoidae (scale worms) and the sole member of the genus ''Augenerilepidonotus''. It is known from Australia, usually from depths of about 40 metres or less. Description Body dorsoventrally flattened, short, with 26 segments and 12 pairs of elytra on segments 2, 4, 5, 7, 9, 11, 13, 15, 17, 19, 21, and 2. Prostomium with three antennae; lateral antennae continuous with prostomium, laterally to median antenna. elytra covered with chitinous irregular polygonal areas. Notochaetae slender and densely serrated. Neurochaetae much more stout, with few rows of spines distally and exclusively unidentate tips (see Pettibone, 1995 for detailed diagnosis) . ''Augenerilepidonotus dictyolepis'' is very similar to species of Lepidonotus, differing only by the polygonal ornamentation of the elytra An elytron (; ; , ) is a modified, hardened forewing of beetles (Coleoptera), though a few of the tru ...

Arctonoe
''Arctonoe'' is a genus of worms belonging to the family Polynoidae. They are commonly known as "scale worms". Members of this genus predominantly occur in shallow (50 metres or less) waters of the northeast Pacific Ocean and often live as commensals of other marine invertebrates, frequently echinoderms but sometimes molluscs or other polychaetes. Description Arctonoe have long bodies, with 100 or more segments and numerous pairs of smooth translucent scales (elytra) on several of the segments. The first segment (prostomium), which contains the mouth, is rounded and smooth; on its side it has antennae pointing away from the body. Parapodia are found along the body with both dorsal (notopodial) and ventral (neuropodial) acicula penetrating epidermis. The notochaetae are few in number and more slender than the neurochaetae both notochaetae and neurochaetae A chaeta or cheta (from Greek χαίτη “crest, mane, flowing hair"; plural: chaetae) is a chitinous bristle or seta fo ...

Antipathipolyeunoa
''Antipathipolyeunoa'' is a genus of marine annelids in the family Polynoidae (scale worms). The genus contains a single species, ''Antipathipolyeunoa nuttingi'', found in the Caribbean Sea at a depth of 91 metres.Pettibone, M.H. (1991). Polynoid polychaetes commensal with antipatharian corals. Proceedings of the Biological Society of Washington. 104(4): 714-726., available online at https://www.biodiversitylibrary.org/page/34809416 Description Species of ''Antipathipolyeunoa'' have 82–84 segments and 40 pairs of elytra; the elytra are large and cover the dorsum completely. Cephalic peaks are also present, and the neuropodia are with a subacicular process. Description of ''Antipathipolyeunoa nuttingi'' Specifically, ''A. nuttingi'' has 82 segments and 40 pairs of elytra, with a nearly continuous reddish brown longitudinal dorsal pigmentation band with some spots at the base of the dorsal cirri and some midventral pigmentation. The lateral antennae are inserted ventrally (be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antinoe (annelid)
In Greek mythology, the name Antinoe (; Ancient Greek: Ἀντινόη) may refer to: * Antinoe, mother of Ancaeus and Epochus by King Lycurgus of Arcadia.Scholia on Apollonius of Rhodes, ''Argonautica'' 1.164 The latter's wife was otherwise known as Cleophyle or Eurynome. *Antinoe, daughter of King Cepheus of Tegea. Instructed by an oracle, she removed the inhabitants of Mantinea from the old settlement founded by Mantineus, son of Lycaon, to a new one. She was guided to the new site by a snake, and from that circumstance the river on the banks of which the new city was founded received the name Ophis (Greek for "snake"). The tomb of Antinoe, known as "The Common Hearth", was shown in Mantinea. * Antinoe, daughter of Pelias, King of Iolcus. She was a sister of Asteropeia. After the sisters had been tricked by Medea into killing their own father, they had to flee from Iolcus to Arcadia, where they ended their days and were buried.Pausanias, 8.11.3; note the contradiction to th ...
