picture info	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 "tubifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Clitellata The Clitellata are a class of annelid worms, characterized by having a clitellum - the 'collar' that forms a reproductive cocoon during part of their life cycles. The clitellates comprise around 8,000 species. Unlike the class of Polychaeta, they do not have parapodia and their heads are less developed. Characteristics Clitellate annelids are segmented worms characterised by the clitellum or girdle which is located near the head end of mature individuals. The mouth is on the ventral surface and is overhung by the prostomium (proboscis). The brain is not located in the head but in one of the body segments. The clitellum is formed by a modification of several segments, and either includes the female gonopores or is located just behind them. During copulation, this glandular tissue secretes mucus that keeps the paired individuals together while they exchange sperm. Afterwards it secretes material that forms a cocoon that encircles the animal's body and encloses the eggs and spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	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 po ...
