Sternaspis (polychaete)
''Sternaspis'' is a genus of annelids belonging to the family Sternaspidae. The genus has cosmopolitan distribution In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The ext ....

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 ...

Sternaspis Scutata
''Sternaspis scutata'' is a species of marine polychaete worm in the family Sternaspidae. It occurs in the Mediterranean Sea and the temperate northeastern Atlantic Ocean. It lives submerged in mud or other soft sediment. Description ''Sternaspis scutata'' is a plump, whitish, barbell-shaped worm growing to a length of about . The anterior region consists of seven segments, the second to fourth segments bearing lateral bundles of chaetae (bristles). This part is narrower and shorter than the posterior part of the worm which has thirteen to fifteen segments. On the underside of the posterior part there are two hard brown chitinous plates forming a shield, the margins of which are rimmed with bundles of long chaetae. A number of long, semi-coiled, thread-like gills arise from the base of the shield. Distribution and habitat The range of ''S. scutata'' includes the Mediterranean Sea and the western Atlantic Ocean as far north as the English Channel; the type locality is the Gulf of ...
