Chrysopelea taprobanica, the Sri Lankan flying snake [3] [4] [5] or Indian flying snake, [2] is a species of gliding colubrid snake distributed in India and Sri Lanka. [1] [2] [6] It can glide, as with all species of its genus Chrysopelea , by stretching the body into a flattened strip using its ribs. The snake is known as "dangara dandaa - දඟරදන්ඩා" in Sinhala, due to its folding postures.

Distribution

The Sri Lankan flying snake is distributed in Sri Lanka and Peninsular India. population in Sri Lanka can be found in dry zone lowlands and parts of the intermediate climatic zones, including Polonnaruwa, Wilpattu National Park, Sigiriya, Kurunegala, Jaffna, Trincomalee, and Monaragala. [5] This species was believed to be endemic to Sri Lanka until researchers recorded a few specimens from Andhra Pradesh (India) [9] [10] and found old museum specimens collected from India that are now assigned to this species. [6] More recently this species has been sighted in parts of Eastern Ghats in Tamil Nadu.

Chrysopelea taprobanica is a medium-sized snake, reaching 60–90 cm (24–35 in) length. The head is depressed. Eyes are large with round pupils. Ventral scales have keels laterally. Vertebral scales are not enlarged. Dorsal scales are smooth or feebly keeled. Dorsal side is greenish yellow or pale green. Orange to red spots can be seen between dark cross bands. Head is black dorsally with yellow and black cross-bars. Ventral side is pale green with a series of black lateral spots on each side. [5]

Scalation

There are 198–214 ventral scales and 107–123 subcaudal scales. [5]

Behavior

Ecology

The snake inhabits old growth trees, as well as secondary vegetation, cultivation, sometimes entering human dwellings. They are diurnal and arboreal. [5]

Diet

Its diet consists mainly of lizards, such as geckos and agamids. Bats, rodents, birds and other small snakes may also be taken. [5]

Reproduction

Chrysopelea taprobanica is oviparous. [2] [5]

Relationship with humans

Because this species is uncommon, arboreal, and prefers forests, it is rarely encountered by humans. One bite has been reliably documented, resulting in mild local effects only. [3]

<i>Chrysopelea</i> Genus of snakes

Chrysopelea, more commonly known as the flying snake or gliding snake, is a genus of snakes that belongs to the family Colubridae. They are found in Southeast Asia, and are known for they ability to glide between trees. Flying snakes are mildly venomous, though the venom is dangerous only to their small prey. There are five species within the genus.

<i>Chrysopelea ornata</i> Species of snake

Chrysopelea ornata is a mildly venomous opisthoglyphous (rear-fanged) colubrid snake found in both South and Southeast Asia. It is commonly known as the golden tree snake, ornate flying snake, and golden flying snake. Along with the other species in the Chrysopelea genus, the golden tree snake is very unusual, as it is capable of a type of gliding "flight" —mainly utilised during the pursuit of prey animals—from tree-to-tree. This action is also used to great effect for the snake to flee its own potential predators. Currently, three subspecies are recognised. The snake's striking looks, and potential for gliding, have made it a coveted choice for captivity.

<i>Chrysopelea paradisi</i> Species of snake

Paradise tree snake or paradise flying snake is a species of colubrid snake found in Southeast Asia. It can, like all species of its genus Chrysopelea, glide by stretching the body into a flattened strip using its ribs. It is mostly found in moist forests and can cover a horizontal distance of 10 meters or more in a glide from the top of a tree. Slow motion photography shows an undulation of the snake's body in flight while the head remains relatively stable, suggesting controlled flight. They are mildly venomous with rear fangs and also can constrict their prey, which consists of mostly lizards and bats.

<i>Ahaetulla</i> Genus of snakes

Ahaetulla, commonly referred to as Asian vine snakes or Asian whip snakes, is a genus of colubrid snakes distributed throughout tropical Asia. They are considered by some scientists to be mildly venomous and are what is commonly termed as 'rear-fanged' or more appropriately, opisthoglyphous, meaning their enlarged teeth or fangs, intended to aid in venom delivery, are located in the back of the upper jaw, instead of in the front as they are in vipers or cobras. As colubrids, Ahaetulla do not possess a true venom gland or a sophisticated venom delivery system. The Duvernoy's gland of this genus, homologous to the venom gland of true venomous snakes, produces a secretion which, though not well studied, is considered not to be medically significant to humans.
