which indian snakes are viviperous (not lay eggs)? in which region are they found?

Answer 1

These are primitive fossorial snakes which have no hindlimb vestiges and eye-covering spectacles. Their name "shield-tailed snakes" is derived from the Greek words ura = tail and pelte = shield, indicating the presence of a large keratinous shield at the tip of the short tail, which differs among genera. They inhabit loose soil and the sharp snout is used for burrowing. Sri Lanka harbors 15 uropeltids, out of which all are endemic to the country. They include the spectacular Sri Lankan Pipe snake (Cylindrophis maculata) and the relict Large shield snake (Pseudotyphlops philippinus). Despite their high endemicity, only very few studied have been conducted on these snakes in the country, and agricultural practices are one of the main threats to there fossorial species. Platyplecturus madurensis ruhunae is only known from the type specimen and is considered to be a doubtful subspecies.

Answer 2

sea snake


name for any of the venomous marine snakes of the family Hydrophidae, found in tropical waters of the Indian and Pacific oceans. The sea snake’s body is flattened laterally and its oarlike tail is used as a scull. A specialized lung and nostrils with valves enable it to remain submerged for periods of up to 8 hr. Most species are dark above and lighter below, or ringed with black and grayish green. They feed on small fish and are preyed upon by sea birds, sharks, and larger fish. Their potent venom quickly immobilizes their prey; however, they are not aggressive and rarely strike at humans when caught. Most sea snakes are completely marine and lack the enlarged ventral scales that enable land snakes to grip the ground. "These snakes bear live young at sea". Most inhabit the shallow waters of the Indonesian region, but the common sea snake, Pelamis platurus, ranges from Madagascar E to Mexico and is sometimes found swarming by the thousands in open ocean. It is black or dark brown above and yellow below and grows up to 3 ft (90 cm) long. A few sea snake species leave the water to lay eggs on coral reefs. These snakes have ventral plates like those of land snakes. Sea snakes are classified in the phylum Chordata, subphylum Vertebrata, class Reptilia, order Squamata, family Hydrophidae.

Answer 3

There are several viviparous species and India abounds in them. There are numerous species of pit vipers, and vipers (Trimersurus and others) and they are found from dry areas to jungles. The cobras and kraits are egg-layers and so are the pythons. The sea snakes give birth to live young. Unlike the American water snakes, the Indian species are not live-bearers but egg layers.

Answer 4

None, all snakes lay eggs. Even all reptiles, amphibians, birds and some mammals. Viviparoussity is unique to the placental-parachorionic mammals and all marsupials.
