The striped keelback (Xenochrophis vittatus) is a species of colubrid snake native to Indonesia. [1] [2] It has also been introduced to Singapore and Puerto Rico. [3] [4] [5]
The striped keelback is a medium sized snake, with females growing to about 70 cm in length and males reaching 50 cm. They are noticeably thin and are colored bronze with black stripes running down the top and sides of the body. The chin and ventral areas of this snake is barred black and white. [6] [7]
The native range of this snake is the western parts of Indonesia, mostly Sumatra and Java. [2] [8] Boulenger reported this species in Sulawesi, but as this was in 1897 and no other records have been made it is likely this snake is not found there.
They have been introduced to Singapore, with the first record in July 1982 at Pandan Gardens. [3] It was first recorded in western Singapore, but has since spread to the eastern parts of the island where it can be found around beaches and mangrove swamps. [7] The white-throated kingfisher has been observed to eat these snakes in Singapore. [3]
This species was first documented from Puerto Rico in 2011 when two adult snakes were found under a steel panel in Toa Baja. [9] It has since been sighted many times in the northeastern part of the island in lowland grassy fields and wetlands. [4] [5] Several specimens had their stomachs examined and were found to have eaten coquis and white-lipped frogs. [9]
This is a diurnal snake that is found in and around aquatic habitats such as ponds, wetlands, and paddies. [1] They also live in open habitats such as fields and meadows. [2] [3] The striped keelback is rear-fanged and mildly venomous, but is considered harmless to humans.
Their diet consists of small animals such as fish, amphibians, and lizards. [1] [2] [10] It is oviparous and lays 5 to 12 eggs in a clutch. Hatchlings are about 13 cm in length. [4] They live for approximately 10 years. [5]
The buff striped keelback is a species of nonvenomous colubrid snake found across Asia. It is a typically nonaggressive snake that feeds on frogs and toads. It belongs to the subfamily Natricinae, and is closely related to water snakes and grass snakes. It resembles an Asian version of the American garter snake. It is quite a common snake but is rarely seen.
The checkered keelback, also known commonly as the Asiatic water snake, is a common species in the subfamily Natricinae of the family Colubridae. The species is endemic to Asia. It is non-venomous.
The Santa Catalina rattlesnake is a species of pit viper endemic to Isla Santa Catalina in the Gulf of California just off the east coast of the state of Baja California Sur, Mexico. Like all other pit vipers, it is venomous. No subspecies are currently recognized. A relatively small and slender species, its most distinctive characteristic is that it lacks a rattle. They are also a generally nocturnal species. Though the species is classified as Critically Endangered on the IUCN Red List, there are few efforts for the snake's conservation.
The Natricinae are a subfamily of colubroid snakes, sometimes referred to as a family (Natricidae). The subfamily comprises 36 genera. Members include many very common snake species, such as the European grass snakes, and the North American water snakes and garter snakes. Some Old World members of the subfamily are known as keelbacks, because their dorsal scales exhibit strong keeling.
Rhabdophis is a genus of snakes in the subfamily Natricinae of the family Colubridae. Species in the genus Rhabdophis are generally called keelback snakes, and are found primarily in Southeast Asia.
The fauna of Puerto Rico is similar to other island archipelago faunas, with high endemism, and low, skewed taxonomic diversity. Bats are the only extant native terrestrial mammals in Puerto Rico. All other terrestrial mammals in the area were introduced by humans, and include species such as cats, goats, sheep, the small Indian mongoose, and escaped monkeys. Marine mammals include dolphins, manatees, and whales. Of the 349 bird species, about 120 breed in the archipelago, and 47.5% are accidental or rare.
The fauna of the United States of America is all the animals living in the Continental United States and its surrounding seas and islands, the Hawaiian Archipelago, Alaska in the Arctic, and several island-territories in the Pacific and in the Caribbean. The U.S. has many endemic species found nowhere else on Earth. With most of the North American continent, the U.S. lies in the Nearctic, Neotropic, and Oceanic faunistic realms, and shares a great deal of its flora and fauna with the rest of the American supercontinent.
The striped crayfish snake is a species of semiaquatic North American snake in the family Colubridae. The species derives its common name from its principal prey, crayfish. This snake is also called Allen's snake, the striped swamp snake, the striped swampsnake, or simply the swamp snake. It is endemic to peninsular Florida. Although rarely seen due to its secretive behavior, it can be found in large numbers in wet areas, with densities approaching 1,300 snakes per hectare.
The northern redbelly snake is a nonvenomous snake in the family Colubridae, a subspecies of Storeria occipitomaculata. It is native to North America.
In the 10th edition of Systema Naturae, Carl Linnaeus described the Amphibia as:
Animals that are distinguished by a body cold and generally naked; stern and expressive countenance; harsh voice; mostly lurid color; filthy odor; a few are furnished with a horrid poison; all have cartilaginous bones, slow circulation, exquisite sight and hearing, large pulmonary vessels, lobate liver, oblong thick stomach, and cystic, hepatic, and pancreatic ducts: they are deficient in diaphragm, do not transpire (sweat), can live a long time without food, are tenatious of life, and have the power of reproducing parts which have been destroyed or lost; some undergo a metamorphosis; some cast (shed) their skin; some appear to live promiscuously on land or in the water, and some are torpid during the winter.
Boulenger's keelback, also known commonly as the Sri Lankan keelback, is a species of water snake in the family Colubridae. The species is endemic to Sri Lanka.
Hebius boulengeri is a species of snake in the family Colubridae. The species is native to East Asia and Southeast Asia. It is also known commonly as the Tai-yong keelback or Boulenger's keelback.
The spotted keelback is a species of snake of the family Colubridae.
Xenochrophis bellulus, the Burmese keelback water snake or Burmese white-barred keelback , is a species of water snake described by Stoliczka in 1871. It is known only from three examples collected in Myanmar, including a recent specimen from 2010.
Fowlea schnurrenbergeri or Xenochrophis schnurrenbergeri is a species of Non venomous snake in the family Colubridae. It is found in Nepal, Pakistan, India and Bangladesh.
Hebius ishigakiensis, the Yaeyama keelback, is a species of snake of the family Colubridae. The snake is endemic to Ishigaki and Iriomote in the Yaeyama Islands of southernmost Japan.
