The monocled cobra (Naja kaouthia) is a cobra species, which is widespread across central andsouthen asia regions They prefer habitats associated with water, such as paddy fields, swamps, and mangroves, but can also be found in grasslands, shrublands, and forests. It also occurs in agricultural land and human settlements, including cities. The monocled cobra has an O-shaped, or monocellate hood pattern, unlike that of the Indian cobra. Coloration in the young is more constant. The dorsal surface may be yellow, brown, gray, or blackish, with or without ragged or clearly defined cross bands. It can be olivaceous or brownish to black above with or without a yellow or orange-colored, O-shaped mark on the hood. It has a black spot on the lower surface of the hood on either side, and one or two black cross-bars on the belly behind it. The rest of the belly is usually of the same color as the back, but paler. As age advances, it becomes paler, when the adult is brownish or olivaceous.
Scientific Name: Naja naja
Adult Size: 4 to 7 feet, sometimes significantly longer
Range: Found in many closely related forms from Pakistan over India and Sri Lanka into western Southeast Asia, south to Malaysia.
Habitat: Indian cobras are found in many habitats but generally prefer open forest edges, fields, and the areas around villages, often with water in the vicinity. They are found anywhere their prey, rats, are abundant.
The common krait (Bungarus caeruleus, also known as Indian krait or blue krait) is a species of genus Bungarus found in the jungles of the Indian subcontinent It is a member of the “Big Four”, species inflicting the most sMales are longer, with proportionately longer tails. The head is flat and the neck hardly evident. The body is cylindrical, tapering towards the tail. The tail is short and rounded. The eyes are rather small, with rounded pupils, indistinguishable in life. The head shields are normal, with no loreals; four shields occur along the margin of the lower lip; the third and fourth supraoculars touch the eye. The scales are highly polished, in 15-17 rows; the vertebral row is distinctly enlarged and hexagonal. Colouration is generally black or bluish black, with about 40 thin, white crossbars which may be indistinct or absent anteriorly. The pattern, however, is complete and well defined in the young, which are marked with conspicuous crossbars even anteriorly; in old individuals, the narrow white lines may be found as a series of connected spots, with a prominent spot on the vertebral region. nakebites in India.
The banded krait (Bungarus fasciatus) is a species of elapid snake found on the Indian subcontinent and in Southeast Asia. It is one of the largest kraits, with a maximum length up to 2.1 m (6 ft 11 in).The longest banded krait measured was 2.25 m (7 ft 5 in) long, but normally the length encountered is 1.8 m (5 ft 11 in).The snake has an entire anal plate and single subcaudals. The tail is small and ends like a fingertip, generally being one-tenth the length of the snake.Banded kraits may be seen in a variety of habitats, ranging from forests to agricultural lands.Banded kraits are shy, not typically seen, and are mainly nocturnal.When harassed, they will usually hide their heads under their coils, and do not generally attempt to bite, though at night they are much more active and widely considered to be more dangerous then.During the day, they lie up in grass, pits, or drains. The snakes are lethargic and sluggish even under provocation. They are most commonly seen in the rains.
Bronzeback tree Snake:
The Bronzeback Dendrelaphis tristis is a species of tree-snake found in South Asia.It is a long,slender snake with a pointed head and a bronze coloured line running down its back. It’s diet includss geckos, birds and occasionally frogs. This harmless snake prefers the tree tops to life on the ground. It is camouflaged (Made invisible by means of protective coloring ) among the leaves because of its uniform ruddy brown skin. This active snake is restless and a quick, both on the ground as well as in the trees. Generally lively and plucky snake, its disposition varies from snake to snake. It is found in southern India and the Himalayan foothills. This oviparous (Egg laying animal e.g. birds) snake lays its eggs between September-February. The 6-7 eggs in a clutch, or number of eggs laid at once, hatch 4-6 weeks after laying and have a gestation period of 4-6 weeks.
The Burmese Python :
The Burmese Python (Python bivittatus) is one of the five largest snake in the world, native to a large variation of tropic and subtropic areas of southern- and Southeast Asia. They are often found near water and are sometimes semi-aquatic, but can also be found in trees. Wild individuals average 3.7 metres (12 ft) long, but may reach up to 5.74 metres (19 ft).Burmese Pythons are dark-colored snakes with many brown blotches bordered in black down the back. The perceived attractiveness of their skin pattern contributes to their popularity with both reptile keepers and the leather industry. Although pythons are typically afraid of people due to their high stature, and will generally avoid people, special care is still required when handling them. A three-metre long Burmese python can easily kill a child and a five-metre long (around 16.5 feet) Burmese python is certainly capable of overpowering and killing a fully grown adult.Burmese Pythons breed in the early spring, with females laying clutches which average 12-36 eggs in March or April. She will remain with the eggs until they hatch, wrapping around them and twitching her muscles in such a way as to raise the ambient temperature around the eggs by several degrees.
Common wolf snake:
A slender-bodied small snake that ranges from barely three feet to less than one meter. Most wild-caught specimens usually reach less than these lengths. Coloration is adapted for life underground and on the forest floor. Shades of jet black, reddish-brown or dark gray with speckles, blotches and spots of white or pale yellow scattered over the body are its usual colors. There is also a distinct white coloration around its neck. Their color patterns vary from one geographic location to another. There are albino-colored ones which are very rare among this snake species. Their snout is duck bill-shaped and is enabled for digging in soft or sandy ground. They have enlarged front teeth but don’t resemble fangs as they are not poisonous. Though the wolf snake is non-venomous, it is quite a nervous snake when picked-up or handled and will not hesitate to bite. They may also move their tails in a to-and-fro motion much like a rattlesnake when they feel threatened. A fossorial animal, it loves burrowing down the earth but is most often found in open ground, on rocks or in low vegetation. Sometimes showing a semi-arboreal behavior. A nocturnal creature, it is most active during the night, but is also observed during daybreak. Most captive specimens become tame after some time and with proper handling.Though a very common snake, it is seldom seen. Continuous destruction of primary and secondary forests, conversion of fertile lands to agricultural and residential areas as well as indiscriminate human killings can threaten the survival of this animal.
Ornata flying Snake:
Flying snakes are mildly venomous though they are considered harmless because their toxicity is not dangerous to humans. It glides by using its ridge scales along its belly, pushing against roughbark surface of tree trunks, allowing it to move vertically up a tree. Upon reaching the end of a tree’s branch, the snake continues moving until its tail dangles from the branch’s end. It then makes a J-shape bend, they hunt during the day, preying upon lizards,frogs, birds and bats.
buff striped keelback :
It is a nonvenomous colubrid snake found across Asia. It is a typically nonaggressive snake that feeds on frogs and toads.A small, slender snake, the buff striped keelback is generally olive-brown to gray in colour. The head and the body are of the same colour.The body of the buff striped keelback is short, and it has a long slender tail which is almost a quarter of its length. Two yellow stripes along the length and to the sides of the spine are the distinctive feature of this snake. These stripes are diffuse at the head and are especially bright on the second half of its body.The keelback has irregular blackish crossbars on the body. Near the head the crossbars are prominent, whereas on the second half of the snake they become diffuse.The Buff Striped keelback is usually 40 to 50 cm (about 16 to 20 inches) in total length. The maximum length recorded is 90 cm (35⅜ inches). Females are consistently longer than the males which only rarely reach 620 mm (2 ft) in length. The buff striped keelback inhabits river banks, marshy areas and wetlands but is also commonly found in fields, open countrysides and overgrown grassy patches during the monsoon season. In Bengali it is called Hele sanp.
vine snake :
vine snake, any of several venomous, rear-fanged snakes of the family Colubraid that have slender bodies, narrow heads, and pointed snouts. Vine snakes typically belong to the genera Ahaetulla (Asian vine snakes), Oxybelis (New World vine snakes), and Thelotornis (African vine snakes); however, some authorities also place the genera Imantodes and Langaha in this group. African vine snakes, which inhabit sub-Saharan regions, are most diverse in East Africa. The five species of New World vine snakes range from Texas in the United States to Peru. Ahaetulla is a tropical Asian genus made up of eight species and distributed through India, Southeast Asia, the Philippines, and the East Indies. Vine snakes appear in two colours. Green species inhabit rainforest areas, and gray or brown species live primarily in savannas or dry forests. The body is laterally compressed and elongate, with the tail accounting for more than one-third of the total length, which typically varies between 0.75 and 1.5 metres (2.5 and 5 feet). Ahaetulla is unique in having a horizontal keyhole-shaped pupil and longitudinal grooves on the sides of its snout that enable acute, binocular vision. In contrast, Oxybelis has a round pupil, and Thelotornis has a horizontally elliptical pupil. All vine snakes are venomous with grooved fangs below the eye; however, most species are relatively harmless to humans, and onlyThelotornis has caused human fatalities.
White lipped PitViper :
It is a Venomous pit viper spices that is endemic to Southeast Asia.Three subspecies are currently recognized, including the nominate race described here. Maximum total length males 600 mm (24 in), females 810 mm (32 in); maximum tail length males 120 mm (4.7 in), females 130 mm.Color pattern: green above, the side of the head below the eyes is yellow, white or pale green, much lighter than rest of head. The belly is green, yellowish or white below. A light ventrolateral stripe is present in all males, but absent in females. The end of tail is not mottled brown.
Worm snake :
Worm snake is the common name sometimes given to several of snakes. They share the characteristics of small size, primarily subterranean habitat, non-functioning or small eyes, and varying resemblance to earthworms. Many are also known as Blind snake, the alternative common name. The worm snake is indeed a snake although there are myths of it possibly being a lizard with very tiny legs. There are also myths of the worm snake possibly being the offspring of a male snake and a female worm, this is not true though. Worm snakes are small — to 13 in (33.5 cm) — brown snakes with smooth shiny scales, tiny eyes, and a pointed tail tip. The body is generally light to dark brown on the dorsum and pink to white below. The belly coloration often extends slightly onto the sides of the body. Juveniles resemble adults in coloration. Worm snakes are among the most fossorial (living underground) snakes in the Southeast and are seldom seen above ground. They are most often encountered hiding beneath logs, rocks, leaf litter, or other debris. Worm snakes feed almost exclusively on earthworms and probably fall prey to a variety of birds, mammals, and other snakes. They probably mate in the fall and spring, and females lay up to 12 eggs in the early summer. Although harmless to humans, this species will often press its pointed tail tip against the captor.In the Coastal Plain, this species is apparently most common in forests adjacent to wetlands or cypress swamps. Like other small fossorial snakes this species is most often found in rotting logs, under rocks, in loose soil, or under leaf litter.
Python is a nonvenomous Snake.It is among the longest snakes known. Most pythons are terrestrial to semiarboreal, and a few, such as the green tree python (Morelia viridis) of Australia and New Guinea, are strongly arboreal. Terrestrial pythons are regularly found near water and are proficient swimmers, but they hunt and eat almost exclusively on land. Larger pythons prey mainly on mammals and birds; smaller species also eat amphibians and reptiles. Pythons have good senses of smell and sight, and most can also detect heat. Pits lying between the lip scales have receptors that are sensitive to infrared radiation and enable pythons to “see” the heat shadow of mammals and birds even during the darkest night. Prey is captured by striking and biting, usually followed by constriction. When swallowing prey, pythons secrete a mucus that contains harmless trace amounts of venom proteins. Pythons are egg layers (oviparous) rather than live-bearers (viviparous). Females of most, if not all, species coil around the eggs, and some actually brood them.
