Checkered Keelback
The checkered keelback (''Fowlea piscator''), 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. Description The eye of ''F. piscator'' is rather small and shorter than its distance from the nostril in the adult. Its rostral scale is visible from above. The internasal scales are much narrowed anteriorly and subtriangular, with the anterior angle truncated and as long as the prefrontal scales. The frontal scale is longer than its distance from the end of the snout, and as long as the parietals or a little shorter. The loreal is nearly as long as it is deep. There are one preocular and three (rarely four) post-oculars. Its temporals are 2+2 or 2+3. There are normally nine upper labials, with the fourth and fifth entering the eye; and five lower labials in contact with the anterior chin-shields, which are shorter than the posterior. The dorsal scales are arra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Assam
Assam (; ) is a state in northeastern India, south of the eastern Himalayas along the Brahmaputra and Barak River valleys. Assam covers an area of . The state is bordered by Bhutan and Arunachal Pradesh to the north; Nagaland and Manipur to the east; Meghalaya, Tripura, Mizoram and Bangladesh to the south; and West Bengal to the west via the Siliguri Corridor, a wide strip of land that connects the state to the rest of India. Assamese and Boro are the official languages of Assam, while Bengali is an additional official language in the Barak Valley. Assam is known for Assam tea and Assam silk. The state was the first site for oil drilling in Asia. Assam is home to the one-horned Indian rhinoceros, along with the wild water buffalo, pygmy hog, tiger and various species of Asiatic birds, and provides one of the last wild habitats for the Asian elephant. The Assamese economy is aided by wildlife tourism to Kaziranga National Park and Manas National Park, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xenochrophis Piscator - Checkered Keelback At Palappuzha (5)
''Xenochrophis'' is a genus of snakes in the subfamily Natricinae of the family Colubridae. The genus is endemic to Asia. Some members have been moved to the genus Fowlea. Etymology The generic nomen of Xenochrophis is presumably derived from the Greek ''xénos'', meaning foreign, strange; ''chros'', meaning color; and ''ophis'', meaning snake. The generic nomen probably refers to the distinctive color pattern of this type species. The gender of this generic name is masculine. Species of ''Xenochrophis'' The following 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.

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as Biophysical environment, environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic index, Biotic factors will include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Autotomy
Autotomy (from the Greek ''auto-'', "self-" and ''tome'', "severing", αὐτοτομία) or self-amputation, is the behaviour whereby an animal sheds or discards one or more of its own appendages, usually as a self-defense mechanism to elude a predator's grasp or to distract the predator and thereby allow escape. Some animals have the ability to regenerate the lost body part later. Autotomy has multiple evolutionary origins and is thought to have evolved at least nine times independently in animalia. The term was coined in 1883 by Leon Fredericq. Vertebrates Reptiles and amphibians Some lizards, salamanders and tuatara when caught by the tail will shed part of it in attempting to escape. In many species the detached tail will continue to wriggle, creating a deceptive sense of continued struggle, and distracting the predator's attention from the fleeing prey animal. In addition, many species of lizards such as ''Plestiodon fasciatus'', '' Cordylosaurus subtessellatus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subcaudal Scales

Ventral Scales
In snakes, the ventral scales or gastrosteges are the enlarged and transversely elongated scales that extend down the underside of the body from the neck to the anal scale. When counting them, the first is the anteriormost ventral scale that contacts the paraventral (lowermost) row of dorsal scales on either side. The anal scale is not counted.Campbell JA, Lamar WW. 2004. The Venomous Reptiles of the Western Hemisphere. 2 volumes. Comstock Publishing Associates, Ithaca and London. 870 pp. 1500 plates. .

Dorsal Scales
In snakes, the dorsal scales are the longitudinal series of plates that encircle the body, but do not include the ventral scales. Campbell JA, Lamar WW (2004). ''The Venomous Reptiles of the Western Hemisphere''. Ithaca and London: Comstock Publishing Associates. 2 volumes. 870 pp. 1,500 plates. . When counting dorsal scales, numbers are often given for three points along the body, for example 19:21:17. These numbers correspond to the number of dorsal scales around the body at a head's length behind the head, at midbody and at a head's length before the vent. If only one number is given, it is for the midbody count. Dorsal scale are easiest to count diagonally, starting with the paraventral scale row. In doing so, it is often noted that certain scale rows are raised, keeled or smooth as opposed to the others.U.S. Navy (1991). ''Poisonous Snakes of the World''. United States Government. New York: Dover Publications Inc. 203 pp. . See also * Snake scales * Anatomical terms of l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Labial Scales
The labial scales are the scales of snakes and other scaled reptiles that border the mouth opening. These do not include the median scales on the upper and lower jawsWright AH, Wright AA. 1957. Handbook of Snakes. Comstock Publishing Associates (7th printing, 1985). 1105 pp. . (rostral and mental scales). The term ''labial'' originates from ''Labium'' (Latin for "lip"), which refers to any lip-like structure. In snakes, there are two different types of labial scales: supralabials and sublabials. The numbers of these scales present, and sometimes the shapes and sizes, are some of many characteristics used to differentiate species from one another. There are two different types of labial scales: * Supralabials are the scales that form part of the upper lip. Also called upper labials. * Sublabials are the scales that form part of the lower lip. Also called infralabials or lower labials. Related scales * Rostral scale: median scale on the tip of the snout bordering the mouth openin ...
