Eastern Mud Turtle
The eastern mud turtle (''Kinosternon subrubrum'') or common mud turtle is a common species of turtle in the family Kinosternidae. The species is endemic to the United States. There are two recognized subspecies. Description The eastern mud turtle is a small and often hard to identify species. It measures in carapace length. The carapace is keelless, lacks any pattern, and varies in color from yellowish to black. The plastron is large and double hinged, and can be yellowish to brown, and may sometimes have a dark pattern. The chin and throat are a yellowish grey, streaked and mottled with brown, while the limbs and tail are grayish. The eye, or iris, of the eastern mud turtle is yellow with dark clouding, and its feet are webbed. Diet The eastern mud turtle is omnivorous and feeds on insects, crustaceans, mollusks, amphibians, carrion, and aquatic vegetation. Smaller eastern mud turtles prey on small aquatic insects, algae, and carrion, whereas larger ones can feed on any ty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pierre Joseph Bonnaterre
Abbé Pierre Joseph Bonnaterre (1752, Aveyron – 20 September 1804, Saint-Geniez-d'Olt) was a French zoology, zoologist who contributed sections on cetaceans, mammals, birds, reptiles, amphibians, fish, and insects to the ''Tableau encyclopédique et méthodique''. He is also notable as the first scientist to study the feral child Victor of Aveyron. Bonnaterre is credited with identifying about 25 new species of fish, and assembled illustrations of about 400 in his encyclopedia work of book. He was the first scientist to study Victor, the wild child of Aveyron, whose life inspired François Truffaut for his film ''The Wild Child''.

Louis Agassiz
Jean Louis Rodolphe Agassiz ( ; ) FRS (For) FRSE (May 28, 1807 – December 14, 1873) was a Swiss-born American biologist and geologist who is recognized as a scholar of Earth's natural history. Spending his early life in Switzerland, he received a PhD at Erlangen and a medical degree in Munich. After studying with Georges Cuvier and Alexander von Humboldt in Paris, Agassiz was appointed professor of natural history at the University of Neuchâtel. He emigrated to the United States in 1847 after visiting Harvard University. He went on to become professor of zoology and geology at Harvard, to head its Lawrence Scientific School, and to found its Museum of Comparative Zoology. Agassiz is known for observational data gathering and analysis. He made institutional and scientific contributions to zoology, geology, and related areas, including multivolume research books running to thousands of pages. He is particularly known for his contributions to ichthyological classification, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turtle
Turtles are an order of reptiles known as Testudines, characterized by a special shell developed mainly from their ribs. Modern turtles are divided into two major groups, the Pleurodira (side necked turtles) and Cryptodira (hidden necked turtles), which differ in the way the head retracts. There are 360 living and recently extinct species of turtles, including land-dwelling tortoises and freshwater terrapins. They are found on most continents, some islands and, in the case of sea turtles, much of the ocean. Like other amniotes (reptiles, birds, and mammals) they breathe air and do not lay eggs underwater, although many species live in or around water. Turtle shells are made mostly of bone; the upper part is the domed carapace, while the underside is the flatter plastron or belly-plate. Its outer surface is covered in scales made of keratin, the material of hair, horns, and claws. The carapace bones develop from ribs that grow sideways and develop into broad flat plates th ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raymond Ditmars
Raymond Lee Ditmars (June 22, 1876 – May 12, 1942) was an American herpetology, herpetologist, writer, public speaker and pioneering natural history filmmaker. Biography Ditmars was fascinated by all animals, but primarily reptiles, obtaining his first snakes at twelve years of age. His parents eventually allowed him to keep all manner of venomous reptiles in the attic of their house at 1666 Bathgate Avenue in the Bronx. Ditmars left school at 16 with no formal qualifications but nevertheless gained a deep understanding of zoology through his own personal study of snakes and other animals in the wild and captivity. Throughout his life, vacations were spent searching for new specimens. Such was his interest and knowledge that he would eventually be regarded as the country's foremost herpetologist. In 1893, Ditmars was hired as an assistant in the Department of Entomology at the American Museum of Natural History, primarily because of his talent as an artist. Four years la ...

Georg Baur
Georg Baur (1859–1898) was a German vertebrate paleontologist and Neo-Lamarckian who studied reptiles of the Galapagos Islands, particularly the Galápagos tortoises, in the 1890s. He is perhaps best known for his subsidence theory of the origin of the Galapagos Islands, where he postulated the islands were the remains of a former landmass, connected to South America via Cocos Island. Early life and education Baur was born in Weisswasser, Bohemia in 1859. He spent his early years Hohenheim near Stuttgart. As his father was a professor of forestry, Baur initially planned to study forestry where his father was a professor. However, while at university he became interested in the fields of geology, paleontology, and botany instead. Career Prior to his work on the Galapagos Islands, Baur was an assistant to Othniel Charles Marsh at Yale University from 1884 until 1890. Baur undertook an expedition to the Galápagos Islands in 1891, leaving New York on May 1, arriving in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kinosternon Subrubrum Hippocrepis
''Kinosternon'' is a genus of small aquatic turtles from the Americas known commonly as mud turtles. Geographic range They are found in the United States, Mexico, Central America, and South America. The greatest species richness is in Mexico, and only three species ('' K. dunni'', '' K. leucostomum'', and '' K. scorpioides'') are found in South America. Description They are very similar to the musk turtles, but generally smaller in size, and their carapaces are not as highly domed. Diet All mud turtles are carnivorous, consuming various aquatic invertebrates, fish, and even carrion.
