Carphophis
''Carphophis'' (common name worm snakes) is a genus of small colubrid snakes endemic to the United States. The genus consists of two species. Description Worm snakes are small snakes, 35 cm (14 in) or less in total length. They are usually a dark brown in color on the upperside, with a lighter-colored, pink or orange underside. They are easily mistaken for other similar species, such as the earth snakes (genus ''Virginia'') and the brown snakes (genus ''Storeria''). They have narrow heads, small eyes, and sharp tail tips. They are not venomous. Behavior Worm snakes are fossorial snakes, and spend the vast majority of their time buried in loose, rocky soil, or under forest leaf litter. They are abundant within their range, but rarely seen due to their secretive nature. Reproduction Little is known about their mating habits, but breeding likely occurs in early spring. The eggs are laid in early summer. Clutch size is normally two to five eggs, and hatching takes place i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carphophis Amoenus Amoenus
The eastern worm snake (''Carphophis amoenus amoenus'') is a subspecies of the worm snake, ''Carphophis amoenus'', a nonvenomous colubrid endemic to the Eastern Woodlands region of North America. The species' range extends from southwest Massachusetts, south to southern Alabama, west to Louisiana and north to Illinois.Ernst CH, Ernst EM. 2003. ''Snakes of the United States and Canada''. Smithsonian Books. Washington and London. ("''Carphophis amoenus''", pp. 53–56.) This species is common in the ecotone between woodlands and wetlands. It may also be found in grasslands adjacent to woodlands.Ernst CH, Barbour RW. (1989) ''Snakes of Eastern North America''. George Mason University Press. Fairfax, Virginia. ("''Carphophis amoenus''", pp. 15–17.) Though this snake can be abundant in parts of its range, it is rarely seen because of its fossorial lifestyle. When not underground, ''C. a. amoenus'' resides mostly under rocks, logs and leaf litter, or burrowed within rotting woody d ...

Carphophis Amoenus
''Carphophis amoenus'', commonly known as the worm snake, is a species of nonvenomous Colubridae, colubrid snake Endemism, endemic to the eastern United States. ''C. amoenus'' can be found east of the Mississippi, from southwest Massachusetts south to southern Alabama west to Louisiana and then north to Illinois.Ernst CH, Ernst EM. 2003. ''Snakes of the United States and Canada.'' Smithsonian Books. Washington and London. ("''Carphophis amoenus''", pp. 53–56.)

Robert Kennicott
Robert Kennicott (November 13, 1835 – May 13, 1866) was an American naturalist and herpetologist. Chronic illness kept Kennicott out of school as a child. Instead, Kennicott spent most of his time outdoors, collecting plants and animals. His father schooled him at home and convinced naturalist Jared Potter Kirtland to take him as an understudy. Soon, Kennicott was providing specimens for the Smithsonian Institution via assistant secretary Spencer Fullerton Baird. Kennicott advocated for the study and protection of native prairie animals in an era when farmers sought to eradicate them. He teamed with Northwestern University to found a natural history museum in 1857, then founded the Chicago Academy of Sciences. While in Chicago he served as a mentor to several young naturalists, including William Healey Dall. He joined the Megatherium Club and studied specimens in Hudson Bay. The Western Union Telegraph Expedition commissioned Kennicott as a scientist for their excursion in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colubrid
Colubridae (, commonly known as colubrids , from la, coluber, 'snake') is a family of snakes. With 249 genera, it is the largest snake family. The earliest species of the family date back to the Oligocene epoch. Colubrid snakes are found on every continent except Antarctica. Description While most colubrids are not venomous (or have venom that is not known to be harmful to humans) and are mostly harmless, a few groups, such as genus ''Boiga'', can produce medically significant injuries. In addition, the boomslang, the twig snakes, and the Asian genus ''Rhabdophis'' have caused human fatalities. Some colubrids are described as opisthoglyphous (often called "rear-fanged"), meaning they have elongated, grooved teeth located in the back of their upper jaws. It is likely that opisthoglyphous dentition evolved many times in the history of snakes and is an evolutionary precursor to the fangs of vipers and elapids, which are located in the front of the mouth.

Virginia (snake)
The smooth earth snake (''Virginia valeriae'') is a species of nonvenomous Natricinae, natricine Colubridae, colubrid snake native to the eastern half of the United States. Etymology The Specific name (zoology), specific name or epithet, ''valeriae'', is in honor of Valeria Biddle Blaney (1828–1900), who collected the first specimen in Kent County, Maryland, and was a first cousin of Spencer Fullerton Baird. Geographic range The smooth earth snake is found from Texas and Iowa to New Jersey and Florida. Description The following is a description of the scalation of ''V. valeriae''. Rostral nearly as deep as broad, visible from above; internasals much shorter than the prefrontals; frontal longer than broad, shorter than the parietals; loreal one and a half to two and a half times as long as deep; two or three postoculars; temporals 1+2; six upper labials, third and fourth entering the eye; four lower labials in contact with the anterior chin shields, which are as long as or shor ...

Egg (biology)
An egg is an organic vessel grown by an animal to carry a possibly fertilized egg cell (a zygote) and to incubate from it an embryo within the egg until the embryo has become an animal fetus that can survive on its own, at which point the animal hatches. Most arthropods such as insects, vertebrates (excluding live-bearing mammals), and mollusks lay eggs, although some, such as scorpions, do not. Reptile eggs, bird eggs, and monotreme eggs are laid out of water and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a warm and favorable temperature range while the embryo grows. When the embryo is adequately developed it hatches, i.e., breaks out of the egg's shell. Some embryos have a temporary egg tooth they use to crack, pip, or break the eggshell or covering. The largest recorded egg is from a whale shark and was in size. Whale shark eggs typically hatch within the mother. At and up to , the o ...

Thomas Say
Thomas Say (June 27, 1787 – October 10, 1834) was an American entomologist, conchologist, and Herpetology, herpetologist. His studies of insects and shells, numerous contributions to scientific journals, and scientific expeditions to Florida, Georgia, the Rocky Mountains, Mexico, and elsewhere made him an internationally known naturalist. Say has been called the father of American descriptive entomology and American conchology. He served as librarian for the Academy of Natural Sciences of Philadelphia, curator at the American Philosophical Society (elected in 1817), and professor of natural history at the University of Pennsylvania. Early life and education Born in Philadelphia into a prominent Religious Society of Friends, Quaker family, Thomas Say was the great-grandson of John Bartram, and the great-nephew of William Bartram. His father, Dr. Benjamin Say, was brother-in-law to another Bartram son, Moses Bartram. The Say family had a house, "The Cliffs" at Gray's Ferry Bridge, ...

Sympatry
In biology, two related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter one another. An initially interbreeding population that splits into two or more distinct species sharing a common range exemplifies sympatric speciation. Such speciation may be a product of reproductive isolation – which prevents hybrid offspring from being viable or able to reproduce, thereby reducing gene flow – that results in genetic divergence. Sympatric speciation may, but need not, arise through secondary contact, which refers to speciation or divergence in allopatry followed by range expansions leading to an area of sympatry. Sympatric species or taxa in secondary contact may or may not interbreed. Types of populations Four main types of population pairs exist in nature. Sympatric populations (or species) contrast with parapatric populations, which contact one another in adjacent but not shared ranges and do not ...
