Dina Lineata
''Erpobdella lineata'' is a leech found in Europe. These leeches show a preference for calcic waters and have a tolerance to pollution. They have a digestive tract that consists of mouth, pharynx, esophagus, six-chambered stomach, three-chambered intestine, rectum, and an anus. Its nervous system contains 21 pairs of cell compartments.

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.

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 polycha ...

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 sperm. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leech
Leeches are segmented parasitic or predatory worms that comprise the subclass Hirudinea within the phylum Annelida. They are closely related to the oligochaetes, which include the earthworm, and like them have soft, muscular segmented bodies that can lengthen and contract. Both groups are hermaphrodites and have a clitellum, but leeches typically differ from the oligochaetes in having suckers at both ends and in having ring markings that do not correspond with their internal segmentation. The body is muscular and relatively solid, and the coelom, the spacious body cavity found in other annelids, is reduced to small channels. The majority of leeches live in freshwater habitats, while some species can be found in terrestrial or marine environments. The best-known species, such as the medicinal leech, ''Hirudo medicinalis'', are hematophagous, attaching themselves to a host with a sucker and feeding on blood, having first secreted the peptide hirudin to prevent the blood from c ...

Erpobdellidae
Erpobdellidae is a family of leeches. It is one of the four families belonging to the suborder Erpobdelliformes of the proboscisless leeches order, Arhynchobdellida. Their members have abandoned the blood feeding habits of their ancestors and are instead predators of aquatic invertebrates. The family previously contained seven genera, but Siddall (2002) synonymized five genera (''Croatobranchus'', ''Dina'', ''Mooreobdella'', ''Trocheta'' and ''Nephelopsis'') into the genus '' Erpobdella'' based on morphogenetic analysis, with the remaining genus ''Motobdella'' possibly a sister group and thus retained. This decision was not accepted by scientific community. The family currently contains 3 genera ''Erpobdella'', ''Dina'' and ''Motobdella''. The genus '' Mimobdella'' was also sometimes included within Erpobdellidae or Gastrostomobdellidae Gastrostomobdellidae is a family of annelids belonging to the order Arhynchobdellida.

Erpobdella
''Erpobdella'' is a genus of leeches in the family (biology), family Erpobdellidae. Members of the genus have three or four pairs of eyes, but never have true jaws, and are typically long. All members do not feed on blood, but instead are predators of small aquatic invertebrates, which they often swallow whole. Species The genus includes species previously classified under the genera ''Croatobranchus'', ''Mooreobdella'', ''Trocheta'' and ''Nephelopsis''. These were synonymized into ''Erpobdella'' by Sidall (2002) after morphogenetic analysis. There are over 30 currently accepted species: * ''Erpobdella adani'' (Tessler, Siddall, & Oceguera-Figueroa, 2018) * ''Erpobdella anoculata'' (Moore, 1898) * ''Erpobdella bhatiai'' Nesemann, 2007 * ''Erpobdella borisi'' Chichocka et al., 2015 * ''Erpobdella bucera'' (Moore, 1953) * ''Erpobdella bykowski'' (Gedroyc, 1913) * ''Erpobdella concolor'' Annandale, 1913 * ''Erpobdella costata'' Sawyer & Shelley, 1976 * ''Erpobdella dubia'' (Moore & ...

Otto Friedrich Müller
Otto Friedrich Müller, also known as Otto Friedrich Mueller (2 November 1730 – 26 December 1784) was a Danish naturalist and scientific illustrator. Biography Müller was born in Copenhagen. He was educated for the church, became tutor to a young nobleman, and after several years' travel with him, settled in Copenhagen in 1767, and married a lady of wealth. His first important works, ''Fauna Insectorum Friedrichsdaliana'' (Leipzig, 1764), and ''Flora Friedrichsdaliana'' (Strasbourg, 1767), giving accounts of the insects and flora of the estate of Frederiksdal, near Copenhagen, recommended him to Frederick V of Denmark, by whom he was employed to continue the ''Flora Danica'' a comprehensive atlas of the flora of Denmark. Müller added two volumes to the three published by Georg Christian Oeder since 1761. The study of invertebrates began to occupy his attention almost exclusively, and in 1771 he produced a work in German on “Certain Worms inhabiting Fresh and Salt Water,†...
