Snakes

Asian vine snake

Ahaetulla prasina, commonly known as the Asian vine snake or the Oriental whipsnake, is a widespread species of tree snake found in South Asia and Southeast Asia. Snout acuminate, projecting, without dermal appendage, rather more than twice as long as the eye. Internasals usually in contact with the labials; one to four small loreals between the prefrontal and the labials ; frontal as long as its distance from the end of the snout or a little longer, a little longer than the parietals; one preocular, in contact with the frontal; two postoculars; temporals 2+2 or 3+3, rarely 1+2; upper labials 9, fourth, fifth, and sixth entering the eye; 4 lower labials in contact with the anterior chin-shields, which are shorter than the posterior. Scales in 15 rows, usually faintly keeled on sacral region. Ventrals 203-234; anal divided; subcaudals 167-203, Bright green, pale olive, or grey-brown, with a yellow line along each side of the lower parts; interstitial skin of the neck black and white. Adults may attain 1.8 m (6 feet) in total length, with a tail .6 m (2 feet) long. Its appearance is very much like those of South American vine snakes. It is a rear-fanged species and is mildly venomous but is not considered a threat to humans. Ahaetulla prasina feeds on small reptiles and amphibians, particularly lizards and tree frogs. 

Brahminy blind snake

Ramphotyphlops braminus is a harmless blind snake species found mostly in Africa and Asia, but has been introduced in many other parts of the world. Completely fossorial, they are often mistaken for earthworms, except that they are not segmented. The specific name is a Latinized form of the word Brahmin, which is a caste among Hindus. No subspecies are currently recognized.

Adults are small and thin. Averaging between 6.35-16.5 cm (2½ to 6½ inches) in length. The head and tail-tip look much the same, with no narrowing of the neck. The rudimentary eyes appear only as a pair of small dots under the head scales. The tip of the tail ends with a tiny pointed spur. The head scales are small and resemble those on the body. There are 20 rows of dorsal scales along the entire body. The coloration of the adults varies from shiny silver gray to charcoal gray or purple. The venter is grayish to brown. Juveniles are colored much the same as the adults. The tiny eyes are covered with translucent scales, rendering these snakes almost entirely blind. The eyes cannot form images, but are still capable of registering light intensity.

Usually occur in urban and agricultural areas. These snakes live underground in ant and termite nests. They are also found under logs, moist leaves and humus in wet forest, dry jungle and even city gardens. The distribution and survival of this group of snakes directly reflects soil humidity and temperature.

golden flying snake 

Chrysopelea ornata golden tree snake, ornate flying snake, golden flying snakeis a colubrid snake found in South and Southeast Asia. It is, along with the other species in its genus Chrysopelea, very unusual in that it is capable of a type of gliding flight. It is also rear-fanged.

Chrysopelea ornata is usually green in color, with black cross-hatching and yellow or gold colored accents. The body, though slender, is far less so than in other tree snakes. It has a flattened head with constricted neck, a blunt nose and large eyes with round pupils. The lateral, sharp and pronounced keeled condition of the ventrals in association with the normal, not enlarged, vertebral row of scales distinguish this snake. The snakes rarely exceed 40 inches (1.0 m) in length, the smallest being measured at 115 millimetres (4.5 in) and the largest being 1,360 mm (4 ft 5½ in) long. The tail is about one-fourth of the total length.

This species is considered mildly venomous, with no confirmed cases of medically significant envenomation.

Chrysopelea ornata, like others of its genus, glides or parachutes. This is presumably done to cover distances faster, to escape predators, to catch prey, or to move around in forests. Flying snakes usually parachute from tree to tree, but sometimes launch themselves from trees onto the ground. They have been known to cross as much as 100m.

It does this by climbing up to a height, which it does easily by virtue of its keeled belly scales, and then launching itself into mid-air. The snake contracts its ventral surface inwards to form a U-shaped concave depression along the entire length of their bodies, holding the outer edges of the ventral scales rigid. This concave surface acts like a parachute, and increases air resistance, allowing the snake to glide forward with the thrust of its launch. The snake undulates through the air, in a swimming-like motion. It holds the tail rigidly upwards, and by twisting the tail from side to side, it attains balance. This motion allows it to propel forward, landing clumsily at the end of its flight.

 he snake is oviparous and six to twelve elongated eggs are laid. Gravid females have been obtained in May and June and hatchlings in June. In Bangkok, according to Smith, mating takes place in June. Hatchlings measure 114–152 mm (4½ to 6 in) long, while the smallest gravid female recorded was 1,093 mm (3 ft 7 in) long.

Green vine snake

 Ahaetulla nasuta, is a slender green tree snake found in India, Sri Lanka, Bangladesh, Burma, Thailand, Cambodia and Vietnam. Not to be confused with Oxybelis fulgidus, which is found in Central and South America.

The green vine snake is diurnal and mildly venomous. The reptile normally feeds on frogs and lizards using its binocular vision to hunt. They are slow moving, relying on camouflaging as a vine in foliage. The snake expands its body when disturbed to show a black and white scale marking. Also, they may open their mouth in threat display and point their head in the direction of the perceived threat. There is a widespread myth in parts of southern India that the species uses its pointed head to blind its human victims.

The species is viviparous, giving birth to young that grow within the body of the mother, enclosed within the egg membrane. They may be capable of delayed fertilization (parthenogenesis is rare but not unknown in snakes) as a female in the London zoo kept in isolation from August, 1885 gave birth in August, 1888. The venom is mild and causes swelling. Symptoms will subside within three days.

 Many-spotted Cat Snake

 Boiga multomaculata,
Also called the Many-spotted Cat Snake, Large-spotted Cat Snake and Marbled Cat-eyed Snake. Boiga multomaculata, is a species of rear-fanged colubrid snakes of the genus Boiga. Adults may attain 77 cm (30 in.) in total length.

 The snake is found in a wide variety of locales, including areas of Western Malaysia, Cambodia, Thailand, Vietnam, Myanmar, India (Assam, Arunachal Pradesh, Miao - Changlang district), Southern China (incl. Hong Kong and Hainan), Indonesia (Java, Sulawesi, Sumatra, Borneo), Bangladesh, Cambodia, Laos, Philippines and Singapore.

Mostly observed hunting just before daybreak, it primarily feeds on lizards such as geckos and small skinks but they will also eat lizard eggs. This snake also frequents branches that are overhanging a water source, thus it may also devour fish in the process.
Being a rear-fanged snake, it is mildly venomous. The effects are the same as most boiga species but because of its size, it never poses any threat. There are no known or recorded fatalities as well.

reticulated python

Python reticulatus is a species of python found in Southeast Asia. Adults can grow to 6.95 m (22.8 ft) in length^[4] but normally grow to an average of 3–6 m (10–20 ft). They are the world's longest snakes and longest reptile, but are not the most heavily built. Like all pythons, they are nonvenomous constrictors and normally not considered dangerous to humans. Although large specimens are powerful enough to kill an adult human, attacks are only occasionally reported.

An excellent swimmer, Python reticulatus has been reported far out at sea and has colonised many small islands within its range. The specific name, reticulatus, is Latin meaning "net-like", or reticulated, and is a reference to the complex color pattern.

This species is the largest snake native to Asia. In general, reticulated pythons with lengths of more than 6 m (20 ft) are rare, though according to the Guinness Book of World Records it is the only extant snake to regularly exceed that length. One of the largest scientifically measured specimens, which was from Balikpapan, East Kalimantan, Indonesia, was measured under anesthesia at 6.95 m (22.8 ft) and weighed 59 kg (130 lb) after not having eaten for 3 months.

 Reticulated pythons are found in Southeast Asia from the Nicobar Islands, northeast India, Bangladesh, Burma, Thailand, Laos, Cambodia, Vietnam, Malaysia, and Singapore, east through Indonesia and the Indo-Australian Archipelago (Sumatra, the Mentawai Islands, the Natuna Islands, Borneo, Sulawesi, Java, Lombok, Sumbawa, Sumba, Flores, Timor, Maluku, Tanimbar Islands) and the Philippines (Basilan, Bohol, Cebu, Leyte, Luzon, Mindanao, Mindoro, Negros, Palawan, Panay, Polillo, Samar, Tawi-Tawi). The reticulated python lives in rain forests, woodlands, and nearby grasslands. It is also associated with rivers and is found in areas with nearby streams and lakes. An excellent swimmer, it has even been reported far out at sea and has consequently colonised many small islands within its range.

 Their natural diet includes mammals and occasionally birds. Small specimens up to 3–4 m (10–14 ft) long eat mainly rodents such as rats, whereas larger individuals switch to prey such as Viverridae (e.g. civets and binturongs), and even primates and pigs. Near human habitation, they are known to snatch stray chickens, cats, and dogs on occasion. Among the largest, fully documented prey items to have been taken are a half-starved Sun Bear of 23 kilograms that was eaten by a 6.95 m (23 ft) specimen and took some ten weeks to digest as well as pigs of more than 60 kg (132 lb).

Oviparous, females lay between 15 and 80 eggs per clutch. At an optimum incubation temperature of 31–32 °C (88–90 °F), the eggs take an average of 88 days to hatch. Hatchlings are at least 2 feet (61 cm) in length.
