The collared reed snake is a species of colubrid snake found in Asia. In Japan, it is also called Miyara's collared snake.
Rhinophis travancoricus, commonly known as the Travancore shieldtail or Tamil Nadu earth snake, is a species of uropeltid snake endemic to India.
Heterodon is a genus of harmless colubrid snakes endemic to North America. They are stout with upturned snouts and are perhaps best known for their characteristic threat displays. Three species are currently recognized. Members of the genus are commonly known as hog-nosed snakes, North American hog-nosed snakes, and sometimes puff adders.
In snakes and amphibians, the canthus, canthal ridge or canthus rostralis, is the angle between the flat crown of the head and the side of the head between the eye and the snout, or more specifically, between the supraocular scale and the rostral scale. It is defined as a sharp ridge in many viperids, but is rounded in most rattlesnakes, for example.
Vipera ammodytes montandoni is a venomous viper subspecies endemic to Bulgaria and southern Romania.
Snakes, like other reptiles, have a skin covered in a scale. Snakes are entirely covered with scales or scutes of various shapes and sizes, known as snakeskin as a whole. A scale protects the body of the snake, aids it in locomotion, allows moisture to be retained within, alters the surface characteristics such as roughness to aid in camouflage, and in some cases even aids in prey capture. The simple or complex colouration patterns are a property of the underlying skin, but the folded nature of scaled skin allows bright skin to be concealed between scales then revealed in order to startle predators.
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 jaws. The term labial originates from Labium, 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.
In scaled reptiles, the ocular scales are those forming the margin of the eye. The name originates from the term oculus which is Latin for "eye" and, in the broadest sense, refers to a scale associated with the eye. The numbers of these scales present, and sometimes the shapes and sizes, are some of many characteristics used to differentiate species from one another.
In reptiles, the supralabial scales, also called upper-labials, are those scales that border the mouth opening along the upper jaw. They do not include the median scale. The term labial originates from Labium, which refers to any lip-like structure. The numbers of these scales present, and sometimes the shapes and sizes, are some of many characteristics used to differentiate species from one another.
In reptiles, the sublabial scales, also called lower-labials or infralabials, are those scales that border the mouth opening along the lower jaw. They do not include the median scale. The term labial originates from labium, which refers to any lip-like structure. The numbers of these scales present, and sometimes the shapes and sizes, are some of many characteristics used to differentiate species from one another.
In snakes, the internasal scales are those on top of the head between the scales that surround the nostrils. They are usually paired and situated just behind the rostral.
In reptiles, the nasorostral is an enlarged and usually paired scale, just behind the rostral.
In snakes, the anal scale is the scale just in front of and covering the cloacal opening. This scale can be either single or paired. When paired, the division is oblique. The anal scale is preceded by the ventral scales and followed by the subcaudal scales.
In snakes, the subcaudal scales are the enlarged plates on the underside of the tail. These scales may be either single or divided (paired) and are preceded by the anal scale.
Rhinophis homolepis, commonly known as Trevelyan's earth snake, is a species of snake in the Uropeltidae family. It is endemic to the rain forests and grasslands of Sri Lanka.
Atractaspis aterrima, commonly known as the slender burrowing asp or mole viper, is a species of fossorial, venomous snake in the family Atractaspididae. The specific epithet, aterrima, meaning "blackest", is the superlative form of the Latin adjective ater, meaning "black".
Polemon barthii, or the Guinea snake-eater, is a species of rear-fanged venomous snake in the family Atractaspididae. The species is endemic to Africa.
Polemon gracilis, or the graceful snake-eater, is a species of venomous rear-fanged snake in the family Atractaspididae. It is endemic to Africa.
Uropeltis shorttii, also known as the Shevaroy Hills earth snake or Shortt's shieldtail snake, is a species of non-venomous snake endemic to the Southern Eastern Ghats of India. This species was first described as Silybura shorttii by Richard Henry Beddome, in 1863. It is found only in the Shevaroy Hills of Salem district in Tamil Nadu state in South India. This species was misclassified into Uropeltis ceylanica, a snake endemic to the Western Ghats, for a long time, till a recent taxonomic study proved it to be a distinct species with a very narrow geographic range. It is a burrowing snake, presumed to be nocturnal; feeding on soft-bodied worms. Becomes active during the rains. This is a "data deficient" species, as it is yet to assessed for its conservation status.
