Diplocardia
''Diplocardia'' is a genus of North American (USA, Mexico) earthworms with 52-57 known species that is remarkably similar to Australian ''Diplotrema'' Spencer, 1900. Species include ''Diplocardia pettiboneae'' (Gates 1977) and ''Diplocardia longa'' (Moore 1904), with bioluminescent mucus. The second largest earthworm in North America is ''Diplocardia meansi (''Gates 1977) and is endemic to Rich Mountain in the Ouachita Mountains The Ouachita Mountains (), simply referred to as the Ouachitas, are a mountain range in western Arkansas and southeastern Oklahoma. They are formed by a thick succession of highly deformed Paleozoic strata constituting the Ouachita Fold and Thr .... References * Blakemore, R.J. (2005).

Diplocardia Longa
''Diplocardia longa'' is a species of earthworm native to North America. It was first described by the American zoologist John Percy Moore in 1904. The type locality is Hawkinsville, Georgia. This worm has bioluminescent properties; its body fluids and the sticky slime it exudes when stimulated emit a bluish glow. Description ''Diplocardia longa'' can grow to a length of about when moderately extended and a diameter of at segment 7 and behind the clitellum. The number of segments varies between about 270 and 330. It is slender and cylindrical, slightly tapering at both ends. At the posterior end it swells slightly into a club-shape before narrowing to the anal opening. The two ends of the worm are brown, the clitellum reddish-brown and the rest of the body is a rather dull salmon pink. The skin is translucent and the veins can be seen distinctly in the less-pigmented regions. Bioluminescence This worm produces bioluminescent mucus, its family Acanthodrilidae being one of ...

Diplocardia Meansi
''Diplocardia meansi'', Means's Giant Earthworm, or Rich Mountain Giant Earthworm, is a species of earthworm endemic to the United States. It is the second longest earthworm in North America. It was discovered by D. Bruce Means on June 11, 1973 in Polk County, Arkansas. and later described by Gates in 1977. It occurs only on Rich Mountain, part of the Ouachita Mountains. Description ''Diplocardia meansi'' only occurs on Rich Mountain, located in Oklahoma Oklahoma (; Choctaw language, Choctaw: ; chr, ᎣᎧᎳᎰᎹ, ''Okalahoma'' ) is a U.S. state, state in the South Central United States, South Central region of the United States, bordered by Texas on the south and west, Kansas on the nor ... and Arkansas. ''D. meansi'' was found by Means while digging for salamanders on Rich Mountain. ''D. meansi'' can be over 18 inches, and is the second longest earthworm in North America. ''D. meansi'' inhabits drier areas of the mountain, and is not found in mesic and satur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acanthodrilidae
The Acanthodrilidae are an ancient and widely distributed family of earthworms which has native representatives in Australia, New Zealand, South Africa, South America, and North America. No native species are known from India (cf. Octochaetidae) nor Asia. The family possibly shows a pre-Pangaean distribution. Membership requires an 'acanthodriline' arrangement of male pores and holoic nephridia.

Animal
Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology.

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] |
Oligochaeta
Oligochaeta () is a subclass of animals in the phylum Annelida, which is made up of many types of aquatic and terrestrial worms, including all of the various earthworms. Specifically, oligochaetes comprise the terrestrial megadrile earthworms (some of which are semiaquatic or fully aquatic), and freshwater or semiterrestrial microdrile forms, including the tubificids, pot worms and ice worms ( Enchytraeidae), blackworms ( Lumbriculidae) and several interstitial marine worms. With around 10,000 known species, the Oligochaeta make up about half of the phylum Annelida. These worms usually have few setae (chaetae) or "bristles" on their outer body surfaces, and lack parapodia, unlike polychaeta. Diversity Oligochaetes are well-segmented worms and most have a spacious body cavity (coelom) used as a hydroskeleton. They range in length from less than up to in the 'giant' species such as the giant Gippsland earthworm (''Megascolides australis'') and the Mekong worm (''Am ...

Haplotaxida
The Haplotaxida are one of two orders within the annelid subclass Oligochaeta, the other being the Lumbriculida. No real common name exists, but they are simply referred to as haplotaxids. Given that the other clitellatan annelids are embedded between and around the Haplotaxida and Lumbriculida, the traditional ''Oligochaeta'' are a paraphyletic assemblage. Thus, the Haplotaxida might eventually be up-ranked to subclass status within the ''Clitellata'' or an expanded Oligochaeta, with the present suborders advancing to order rank. The latter – though without merging the ''Oligochaeta'' and ''Clitellata'' – has been proposed time and again in the past, most prominently for the distinct ''Moniligastrina.'' Families Of the four suborders of Haplotaxida, two are minor lineages, monotypic at family level. Another one, the Tubificina, is sizeable and contains the aquatic worms, while the fourth, the earthworms or Lumbricina, unites the bulk of the order's families: Suborder Ha ...

Garmon
The garmon ( rus, гармо́нь, p=gɐˈrmonʲ, links=yes, from rus, гармо́ника, p=gɐˈrmonʲɪkə, r=garmonika, cognate of English ''harmonica''), commonly called garmoshka, is a kind of Russian button accordion, a Free reed aerophone, free-reed wind instrument.

Many instruments have additional right-hand buttons with useful Accidental (music), accidental notes, additional left-hand chords for playing in related keys, and a row of Free-bass system, free-bass buttons, to facilitate playing of bass (music), bass melody, melodies. The term "Garmon" means overcomer, winner or "noble" believed epistemologically to derive from the term for "blue" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ouachita Mountains
The Ouachita Mountains (), simply referred to as the Ouachitas, are a mountain range in western Arkansas and southeastern Oklahoma. They are formed by a thick succession of highly deformed Paleozoic strata constituting the Ouachita Fold and Thrust Belt, one of the important orogenic belts of North America. The Ouachitas continue in the subsurface to the northeast, where they make a poorly understood connection with the Appalachians and to the southwest, where they join with the Marathon uplift area of West Texas. Together with the Ozark Plateaus, the Ouachitas form the U.S. Interior Highlands. The highest natural point is Mount Magazine at . The Ouachita Mountains is a Level III ecoregion designated by the Environmental Protection Agency (EPA). The region has been subdivided into six Level IV ecoregions. Etymology Louis R. Harlan claimed that "Ouachita" is composed of the Choctaw words ''ouac'' for "buffalo" and ''chito'' for "large", together meaning "country of large bu ...
