Alligator Snapping Turtle
The alligator snapping turtle (''Macrochelys temminckii'') is a large species of turtle in the family Chelydridae. The species is native to freshwater habitats in the United States. ''M. temminckii'' is one of the heaviest freshwater turtles in the world. It is the largest freshwater species of turtle in North America. It is often associated with, but not closely related to, the common snapping turtle, which is in the genus ''Chelydra''. The specific epithet ''temminckii'' is in honor of Dutch zoologist Coenraad Jacob Temminck. Taxonomy Although it was once believed that only one extant species exists in the genus ''Macrochelys'', recent studies have shown that there are two species, the other being the Suwannee snapping turtle (''M. suwanniensis'') of the Suwannee River. A third species, the Apalachicola snapping turtle (''M. apalachicolae''), has been proposed, but is generally not recognized. The alligator snapping turtle is given its common name because of its immen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gerald Troost
Gerardus Troost (March 5, 1776 – August 14, 1850) was a Dutch-American medical doctor, naturalist, mineralogist, and founding member and first president of the Philadelphia Academy of Natural Sciences.; archive.org copie Biography Troost was born in Den Bosch, Netherlands, to Anna Cornelia (Van Heeck) and Everardus Josephus Troost. He received the degree of Doctor of Medicine from the University of Leyden, and of Master in Pharmacy, in 1801, from the University of Amsterdam. After a brief practice at Amsterdam and the Hague, he was enlisted in the army as a private soldier, and then as an officer of the first class in the medical department. During these periods of service, he was wounded in the thigh and in the head. In 1807 Troost went to Paris under the patronage of Louis Napoleon, King of Holland. There he studied at the School of Mines with renowned mineralogist René Just Haüy. While in Paris, he translated into the Dutch language one of the earlier works of Alexande ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suwannee Snapping Turtle
The Suwannee snapping turtle (''Macrochelys suwanniensis'') is a species of very large freshwater turtle in the family Chelydridae. This species is endemic to the southeastern United States, where it only inhabits the Suwannee River basin. Taxonomy It is one of only two known species in the genus ''Macrochelys'', the other being the far more widespread alligator snapping turtle (''M. temminckii''); a third, the Apalachicola snapping turtle (''M. apalachicolae''), which was described alongside ''M. suwanniensis'', is not thought to be distinct from ''M. temminckii'' and has been synonymized with it. It was previously believed to represent a population of ''Macrochelys temminckii'', but a 2014 study found significant genetic divergence between the Suwannee and alligator snapping turtles, dating back to the late Miocene to early Pliocene, about 5.5 to 13.4 million years ago, and thus the Suwannee population was described as a distinct species, ''M. suwanniensis''.

Macrochelys
''Macrochelys'' is a genus of very large freshwater turtles in the family Chelydridae from Southeastern United States. Only a single extant species was recognized until a 2014 study divided it into two, or possibly three species.

Extant Taxon
Neontology is a part of biology that, in contrast to paleontology, deals with living (or, more generally, '' recent'') organisms. It is the study of extant taxa (singular: extant taxon): taxa (such as species, genera and families) with members still alive, as opposed to (all) being extinct. For example: * The moose (''Alces alces'') is an extant species, and the dodo (''Raphus cucullatus'') is an extinct species. * In the group of molluscs known as the cephalopods, there were approximately 600 extant species and 7,500 extinct species. A taxon can be classified as extinct if it is broadly agreed or certified that no members of the group are still alive. Conversely, an extinct taxon can be reclassified as extant if there are new discoveries of living species ("Lazarus species"), or if previously-known extant species are reclassified as members of the taxon. Most biologists, zoologists, and botanists are in practice neontologists, and the term neontologist is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coenraad Jacob Temminck
Coenraad Jacob Temminck (; 31 March 1778 – 30 January 1858) was a Dutch aristocrat, zoologist and museum director. Biography Coenraad Jacob Temminck was born on 31 March 1778 in Amsterdam in the Dutch Republic. From his father, Jacob Temminck, who was treasurer of the Dutch East India Company with links to numerous travellers and collectors, he inherited a large collection of bird specimens. His father was a good friend of Francois Levaillant who also guided Coenraad. Temminck's ''Manuel d'ornithologie, ou Tableau systématique des oiseaux qui se trouvent en Europe'' (1815) was the standard work on European birds for many years. He was also the author of ''Histoire naturelle générale des Pigeons et des Gallinacées'' (1813–1817), ''Nouveau Recueil de Planches coloriées d'Oiseaux'' (1820–1839), and contributed to the mammalian sections of Philipp Franz von Siebold's ''Fauna japonica'' (1844–1850).

Zoology
Zoology ()The pronunciation of zoology as is usually regarded as nonstandard, though it is not uncommon. is the branch of biology that studies the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems. The term is derived from Ancient Greek , ('animal'), and , ('knowledge', 'study'). Although humans have always been interested in the natural history of the animals they saw around them, and made use of this knowledge to domesticate certain species, the formal study of zoology can be said to have originated with Aristotle. He viewed animals as living organisms, studied their structure and development, and considered their adaptations to their surroundings and the function of their parts. The Greek physician Galen studied human anatomy and was one of the greatest surgeons of the ancient world, but after the fall of the Western Roman Empire ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term fo ...

Chelydra
''Chelydra'' is one of the two extant genera of the snapping turtle family, Chelydridae, the other being ''Macrochelys'', the much larger alligator snapping turtle. The snapping turtles are native to the Americas, with ''Chelydra'' having three species, one in North America and two in Central America, one of which is also found in northwestern South America. Species The genus ''Chelydra'' has the following species: * ''Chelydra acutirostris'' ( W. Peters, 1862) – South American snapping turtle * ''Chelydra rossignonii'' ( Bocourt, 1868) – Central American snapping turtle * '' Chelydra serpentina'' (Linnaeus, 1758) – common snapping turtle (North America) * ''Chelydra floridana''† * ''Chelydra laticarinata''† * ''Chelydra sculpta ''Chelydra'' is one of the two extant genera of the snapping turtle family, Chelydridae, the other being ''Macrochelys'', the much larger alligator snapping turtle.

Common Snapping Turtle
The common snapping turtle (''Chelydra serpentina'') is a species of large freshwater turtle in the family Chelydridae. Its natural range extends from southeastern Canada, southwest to the edge of the Rocky Mountains, as far east as Nova Scotia and Florida. The three species of '' Chelydra'' and the larger alligator snapping turtles (genus '' Macrochelys'') are the only extant chelydrids, a family now restricted to the Americas. The common snapping turtle, as its name implies, is the most widespread. The common snapping turtle is noted for its combative disposition when out of the water with its powerful beak-like jaws, and highly mobile head and neck (hence the specific epithet ''serpentina'', meaning "snake-like"). In water, it is likely to flee and hide underwater in sediment. The common snapping turtle has a life-history strategy characterized by high and variable mortality of embryos and hatchlings, delayed sexual maturity, extended adult longevity, and iteroparity (repea ...
