Annelids
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 polychae ...

Naididae
The Naididae (including the former family Tubificidae) are a family of clitellate oligochaete worms like the sludge worm, ''Tubifex tubifex''. They are key components of the benthic communities of many freshwater and marine ecosystems. In freshwater aquaria they may be referred to as detritus worms. Description These worms can vary in size, from centimeters to millimeters, depending on the subfamily. They are all hermaphroditic and lack a larval stage. Taxonomy Analysis of 18S rDNA sequences revealed that the tradition family Tubificidae is not monophyletic, with the traditionally circumscribed Naididae nested within tubidicid taxa. To avoid paraphyly the naidid and tubificid taxa were included in a combined family, which took the name Naididae because it has priority under ''International Code of Zoological Nomenclature'' rules as the senior synonym of Tubificidae. A proposal to the International Commission on Zoological Nomenclature to suppress Naididae, because the "tubificid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
