Chtonobdella Fallax
''Chtonobdella fallax'' is a species of leeches belonging to the family Haemadipsidae; also known by its synonym ''Malagabdella fallax'' and having originally been placed in the related jawed land leech genus '' Haemadipsa'' by Raphaël Blanchard in 1917.Blanchard R (2017Monographie des hémadipsines (sangsues terrestres). ''Bulletin de la Societe de Pathologie Exotique''10: 640–675. It is a relatively common species in the tropical forests of Madagascar Madagascar, officially the Republic of Madagascar, is an island country that includes the island of Madagascar and numerous smaller peripheral islands. Lying off the southeastern coast of Africa, it is the world's List of islands by area, f .... ''C. fallax'' is notable in that (before final identification) video evidence was provided by Mai Fahmy and Michael Tessler of this species gathering energy and springing off a leaf, resolving a long-standing debate about whether or not leeches could jump.

Leech
Leeches are segmented parasitism, parasitic or Predation, predatory worms that comprise the Class (biology), subclass Hirudinea within the phylum Annelida. They are closely related to the Oligochaeta, 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 ring markings that do not correspond with their internal segmentation. The body is muscular and relatively solid; 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 pepti ...

Haemadipsidae
__NOTOC__ Haemadipsidae (From Greek "haima" and "dipsa" ("blood" and "thirst", respectively)) are a family of jawed leeches. They are a monophyletic group of hirudiniform proboscisless leeches. These leeches have five pairs of eyes, with the last two separated by two eyeless segments. The family is monotypic, containing only the subfamily Haemadipsinae. However, the family can apparently be divided into two or three distinct lineages. At least one of the proposed splits, while not a distinct family, might be a valid subfamily. Haemadipsids have two or three jaws. The two-jawed (duognathous) species were classified in a number of largely monotypic or non-monophyletic genera, so they were placed into a single monophyletic genus called ''Chtonobdella''. To increase grip, their caudal suckers have textured "friction" or "sucker" rays. Commonly known as jawed land leeches, these annelids are known from subtropical and tropical regions around the Indian and Pacific Ocean. Well-kn ...

Haemadipsa
''Haemadipsa'' is a genus of leeches, with members commonly known as ''jawed land leeches''. These annelids are known from subtropical and tropical regions around the Indian and Pacific Ocean. Well-known ''Haemadipsa'' are for example the Indian Leech (''Haemadipsa sylvestris'') and the yamabiru or Japanese Mountain Leech (''Haemadipsa zeylanica''). Members of the genus feed on blood. They are troublesome to humans and animals especially because their bites result in prolonged bleeding.

Raphaël Blanchard
Raphaël Anatole Émile Blanchard (28 February 1857 – 7 February 1919) was a French physician and naturalist who was a pioneer of medical zoology, with studies on parasites ranging from protozoa to worms and insects. Life and work Blanchard was born in Saint-Christophe-sur-le-Nais where his father Rene was a poet and writer. He was a great grand nephew of the balloonist and parachute inventor Jean Pierre Blanchard. He went to study medicine in Paris in 1874. He became interested in zoology and worked at the laboratory at the École des Hautes-Études where he became a histological preparator for Charles Robin and Georges Pouchet, the latter influencing him towards studies on experimental teratology (inducing mutations and malformations). He travelled around Europe in 1877 with a grant from the Paris City Council, studying embryology in Vienna and comparative anatomy in Bonn. He received another grant in 1880 to study the organization of universities and biological educat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Forest
Tropical forests are forested ecoregions with tropical climates – that is, land areas approximately bounded by the Tropic of Cancer, tropics of Cancer and Tropic of Capricorn, Capricorn, but possibly affected by other factors such as prevailing winds. Some tropical forest types are difficult to categorize. While forests in temperate climate, temperate areas are readily categorized on the basis of tree canopy density, such schemes do not work well in tropical forests. There is no single scheme that defines what a forest is, in tropical regions or elsewhere.Anatoly Shvidenko, Charles Victor Barber, Reidar Persson et al. 2005 "Millennium Ecosystem Assessment." Ecosystems and human wellbeing: a framework for assessment Washington, DC: Island Press Because of these difficulties, information on the extent of tropical forests varies between sources. However, tropical forests are extensive, making up just under half the world's forests. The tropical domain has the largest proportion of ...

Madagascar
Madagascar, officially the Republic of Madagascar, is an island country that includes the island of Madagascar and numerous smaller peripheral islands. Lying off the southeastern coast of Africa, it is the world's List of islands by area, fourth largest island, the List of island countries, second-largest island country, and the List of countries and dependencies by area, 46th largest country overall. Its capital and List of cities in Madagascar, largest city is Antananarivo. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from Africa during the Early Jurassic period, around 180 million years ago, and separated from the Indian subcontinent approximately 90 million years ago. This isolation allowed native plants and animals to evolve in relative seclusion; as a result, Madagascar is a biodiversity hotspot and one of the world's 17 megadiverse countries, with over 90% of its wildlife of Madagascar, wildlife being endemic. The island has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Of Madagascar
The fauna of Madagascar is a part of the wildlife of Madagascar. Madagascar has been an isolated island for about 70 million years, breaking away from Africa around 165 million years ago, then from India nearly 100 million years later. This isolation led to the development of a unique endemic fauna. Before humans arrived about 2,000 years ago, there were many large and unusual animals living there, descended from species that were originally present when Madagascar became an island, or from species that later crossed the sea to Madagascar. Ecological niches were often filled by animals with quite different histories from those on the African mainland, often leading to convergent evolution. A large proportion of these endemic Malagasy animals have died out since the arrival of humans, most particularly the megafauna. Despite this, and massive deforestation, Madagascar is still home to an incredible array of wildlife, the vast majority of which is unique in the world. Mada ...

Animals Described In 1917
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia (). With few exceptions, animals consume organic material, breathe oxygen, have myocytes and are able to move, can reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development. Animals form a clade, meaning that they arose from a single common ancestor. Over 1.5 million living animal species have been described, of which around 1.05 million are insects, over 85,000 are molluscs, and around 65,000 are vertebrates. It has been estimated there are as many as 7.77 million animal species on Earth. Animal body lengths range from to . They have complex ecologies and interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology, and the study of animal behaviour is known as ethology. The animal kingdom is divided into five major clades, namely Porifera, Ctenophora, Placozoa, C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
