Dipsadinae
Dipsadinae is a large subfamily of colubroid snakes, sometimes referred to as a family (Dipsadidae). Species of the subfamily Dipsadinae are found in most of the Americas, including the West Indies, and are most diverse in South America. There are more than 700 member species. Dipsadinae are an ecologically and morphologically diverse group of mostly small to moderate-sized snakes, typically less than in total length. Some are arboreal, but others are aquatic or terrestrial and may even burrow. Most are oviparous. Many eat frogs or lizards, and some consume mammals and birds. Several genera (e.g. '' Adelphicos'', '' Atractus'', '' Geophis'', '' Dipsas'', '' Ninia'', '' Sibon'', '' Sibynomorphus'', '' Tropidodipsas'') are specialized feeders on gooey and slimy prey, such as frog eggs, earthworms, snails, and slugs. Almost all species are completely harmless to humans, although a few genera (e.g. '' Borikenophis'', '' Cubophis'', '' Heterodon'', '' Hydrodynastes'', ''Philodryas'') ...

Emmett Reid Dunn
Emmett Reid Dunn (November 21, 1894 – February 13, 1956) was an American herpetologist and educator who worked in Panama and studied salamanders in the Eastern United States. Early life and education Emmett Reid Dunn was born on November 21, 1894, in Arlington, Virginia, to Emmett Clark Dunn, a civil engineer, and Mary Reid. He spent much of his childhood at a family farm near the James River in Nelson County. He attended Haverford College in Philadelphia, receiving his B.A. and M.A. in 1915 and 1916, respectively. His childhood connection to Arlington allowed him to connect with his first professional mentor, Leonhard Stejneger, the Curator of Reptiles and Amphibians at the Smithsonian Institution, who in 1913 suggested he study salamanders. Henry Sherring Pratt, his professor at Haverford, also guided him. He received his PhD from Harvard University in 1921. Career In 1915, Dunn began publishing scientific papers on snakes and herpetofauna, based on field research he cond ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colubridae
Colubridae (, commonly known as colubrids , from , 'snake') is a family of snakes. With 249 genera, it is the largest snake family. The earliest fossil species of the family date back to the Late Eocene epoch, with earlier origins suspected. Colubrid snakes are found on every continent except Antarctica. Description Colubrids are a very diverse group of snakes. They can exhibit many different body styles, body sizes, colors, and patterns. They can also live in many different types of habitats including aquatic, terrestrial, semi-arboreal, arboreal, desert, mountainous forests, semi-fossorial, and brackish waters. A primarily shy and harmless group of snakes, the vast majority of colubrids are not venomous, nor do most colubrids produce venom that is medically significant to mammals. However, the bites of some can escalate quickly to emergency situations. Furthermore, within the Colubridae, the South African boomslang and twig snakes, as well as the Asian keelback snakes (' ...

Species
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. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists 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. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
