Kingsnake
Kingsnakes are colubrid New World members of the genus ''Lampropeltis'', which includes 26 species. Among these, about 45 subspecies are recognized. They are nonvenomous and ophiophagous in diet. Description Kingsnakes vary widely in size and coloration. They can be as small as 24" (61cm) or as long as 60" (152cm). Some kingsnakes are colored in muted browns to black, while others are brightly marked in white, reds, yellows, grays, and lavenders that form rings, longitudinal stripes, speckles, and saddle-shaped bands. Most kingsnakes have quite vibrant patterns. Some species, such as the scarlet kingsnake, Mexican milk snake, and red milk snake, have coloration and patterning that can cause them to be confused with the highly venomous coral snakes. One of the mnemonic rhymes to help people distinguish between coral snakes and their nonvenomous lookalikes in the United States is "red on black, a friend of Jack; red on yellow, kill a fellow". Other variations include "red on ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scarlet Kingsnake
The scarlet kingsnake or scarlet milk snake (''Lampropeltis elapsoides'') is a species of kingsnake found in the southeastern and eastern portions of the United States. Like all kingsnakes, they are nonvenomous. They are found in pine flatwoods, hydric hammocks, pine savannas, mesic pine-oak forests, prairies, cultivated fields, and a variety of suburban habitats; not unusually, people find scarlet kingsnakes in their swimming pools, especially during the spring. Until recently, and for much of the 20th century, scarlet kingsnakes were considered a subspecies of the milk snake; however, Pyron and Bubrink demonstrated the phylogenetic distinction of this species and its closer relationship to the mountain kingsnakes of the southwestern United States. These largely fossorial snakes are the smallest of all the species within the genus ''Lampropeltis'', usually ranging from at maturity. The maximum recorded length is in Jonesboro, AR . Hatchlings range in size from . Taxonomy Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rattlesnakes
Rattlesnakes are venomous snakes that form the genera '' Crotalus'' and '' Sistrurus'' of the subfamily Crotalinae (the pit vipers). All rattlesnakes are vipers. Rattlesnakes are predators that live in a wide array of habitats, hunting small animals such as birds and rodents. Rattlesnakes receive their name from the rattle located at the end of their tails, which makes a loud rattling noise when vibrated that deters predators or serves as a warning to passers-by. Rattlesnakes are the leading contributor to snakebite injuries in North America, but rarely bite unless provoked or threatened; if treated promptly, the bites are seldom fatal. The 36 known species of rattlesnakes have between 65 and 70 subspecies, all native to the Americas, ranging from British Columbia through Ontario in southern Canada, to central Argentina. The largest rattlesnake, the eastern diamondback, can measure up to in length. Rattlesnakes are preyed upon by hawks, weasels, king snakes, and a variety ...

Ophiophagy
Ophiophagy (Greek "snake eating") is a specialized form of feeding or alimentary behavior of animals which hunt and eat snakes. There are ophiophagous mammals (such as the skunks and the mongooses), birds (such as snake eagles, the secretarybird, and some hawks), lizards (such as the common collared lizard), and even other snakes, such as the Central and South American mussuranas and the North American common kingsnake. The genus of the venomous king cobra (''Ophiophagus hannah'') is named for this habit. Ophiophagy in myth and legend :''The mythic associations of snakes are discussed at Serpent (symbolism).'' A snake-eating bird of prey appears in a legend of the Mexican people, who gave rise to the Aztec empire, and it is represented in the Mexican flag: The Mexicas, guided by their god Huitzilopochtli, sought a place where the bird landed on a prickly pear cactus, devouring a snake. They found the sign on an island in Lake Texcoco, where they erected the city of Tenoc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coral Snake
Coral snakes are a large group of elapid snakes that can be divided into two distinct groups, the Old World coral snakes and New World coral snakes. There are 16 species of Old World coral snakes, in three genera (''Calliophis'', '' Hemibungarus'', and '' Sinomicrurus''), and over 65 recognized species of New World coral snakes, in two genera ('' Micruroides'' and ''Micrurus''). Genetic studies have found that the most basal lineages have origins in Asia, suggesting that the group originated in the Old World. While new world species of both genera are venomous, their bites are seldom lethal; only two confirmed fatalities have been documented in the past 100 years from the genus ''Micrurus''. Meanwhile, snakes of the genus ''Micruroides'' have never caused a medically-significant bite. North American coloration patterns Experts now recognize that certain coloration patterns and common mnemonics - such as the phrase “Red touch yellow, kill a fellow; red touch black, you’re g ...

Cottonmouth
''Agkistrodon piscivorus'' is a species of pit viper in the subfamily Crotalinae of the family Viperidae. It is one of the world's few semiaquatic vipers (along with the Florida cottonmouth), and is native to the southeastern United States. As an adult, it is large and capable of delivering a painful and potentially fatal bite. When threatened, it may respond by coiling its body and displaying its fangs. Individuals may bite when feeling threatened or being handled in any way. It tends to be found in or near water, particularly in slow-moving and shallow lakes, streams, and marshes. It is a capable swimmer and, like several species of snakes, is known to occasionally enter bays and estuaries and swim between barrier islands and the mainland. Gloyd HK, Conant R (1990). ''Snakes of the ''Agkistrodon'' Complex: A Monographic Review''. Society for the Study of Amphibians and Reptiles. 614 pp. 52 plates. LCCN 89-50342. .

Venomous Snake
Venomous snakes are species of the suborder Serpentes that are capable of producing venom, which they use for killing prey, for defense, and to assist with digestion of their prey. The venom is typically delivered by injection using hollow or grooved fangs, although some venomous snakes lack well-developed fangs. Common venomous snakes include the families Elapidae, Viperidae, Atractaspididae, and some of the Colubridae. The toxicity of venom is mainly indicated by murine , while multiple factors are considered to judge the potential danger to humans. Other important factors for risk assessment include the likelihood that a snake will bite, the quantity of venom delivered with the bite, the efficiency of the delivery mechanism, and the location of a bite on the body of the victim. Snake venom may have both neurotoxic and hemotoxic properties. There are about 600 venomous snake species in the world. Evolution The evolutionary history of venomous snakes can be traced back to ...

Miocene
The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Of Prey
Birds of prey or predatory birds, also known as raptors, are hypercarnivorous bird species that actively hunt and feed on other vertebrates (mainly mammals, reptiles and other smaller birds). In addition to speed and strength, these predators have keen eyesight for detecting prey from a distance or during flight, strong feet with sharp talons for grasping or killing prey, and powerful, curved beaks for tearing off flesh. Although predatory birds primarily hunt live prey, many species (such as fish eagles, vultures and condors) also scavenge and eat carrion. Although the term "bird of prey" could theoretically be taken to include all birds that actively hunt and eat other animals, ornithologists typically use the narrower definition followed in this page, excluding both piscivorous predators such as storks, herons, gulls, skuas, penguins and kingfishers, as well as primarily insectivorous birds such as passerine birds (e.g. shrikes) and birds like nightjars and frog ...
