Bylgides
''Bylgides'' is a genus of marine annelids in the family Polynoidae (scale worms). The genus contains 9 species, all found in the Northern Hemisphere and from shallow inshore waters to depths of about 5000 m. Description Body short, 39 segments, 16 pairs of elytron (Annelida), elytra. Anterior margin of prostomium with a pair of acute anterior peaks. Lateral antennae inserted ventrally (beneath prostomium and median antenna). Palps, antennae, dorsal and ventral cirri with papillae. Notochaetae about as thick as neurochaetae. Unidentate and bidentate neurochaetae present. Species of ''Bylgides'' are short-bodied scale worms, with 34 to 39 segments and 14 or 15 pairs of elytron (Annelida), elytra; the elytra have a marginal fringe of short papillae. The prostomium is rounded and bilobed anteriorly, with a pair of cephalic peaks. The antennae are covered with slender papillae and are located ventral to the prostomium; the pair of lateral antennae are inserted ventral (direct ...

Bylgides Groenlandicus
''Bygides groenlandicus'' is a marine scale worm that lives in cold waters. Description It has 39 segments and is 70 millimeters (about 2.76 inches) in length. It possesses very long, filamentous chaetae. It scales are brown on its dorsal, medial, and posterior sides, and its ventral side is grey or colorless. Two bands of lighter color run across its dorsal side. Distribution It is found in the Arctic and North Atlantic waters, as well as off the coast of Massachusetts, the Gulf of Maine, and Newfoundland Newfoundland and Labrador (; french: Terre-Neuve-et-Labrador; frequently abbreviated as NL) is the easternmost province of Canada, in the country's Atlantic region. The province comprises the island of Newfoundland and the continental region .... References External links World Register of Marine Species page Phyllodocida {{Annelid-stub ...

Polynoidae
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 pre ...

Annelid
The annelids (Annelida , from Latin ', "little ring"), also known as the segmented worms, are a large phylum, with over 22,000 extant species including ragworms, earthworms, and leeches. The species exist in and have adapted to various ecologies – some in marine environments as distinct as tidal zones and hydrothermal vents, others in fresh water, and yet others in moist terrestrial environments. The Annelids are bilaterally symmetrical, triploblastic, coelomate, invertebrate organisms. They also have parapodia for locomotion. Most textbooks still use the traditional division into polychaetes (almost all marine), oligochaetes (which include earthworms) and leech-like species. Cladistic research since 1997 has radically changed this scheme, viewing leeches as a sub-group of oligochaetes and oligochaetes as a sub-group of polychaetes. In addition, the Pogonophora, Echiura and Sipuncula, previously regarded as separate phyla, are now regarded as sub-groups of ...
