Which Snakes Give Birth to Live Young? So, which snakes give birth to live young? As mentioned above, both viviparous species (no eggs) and ovoviviparous species (egg retained inside the body) produce live and fully functional baby snakes. Most vipers, and all of the rattlesnakes, fall into this category.
Ovoviviparity. Ovoviviparous animals are similar to viviparous species in which there is internal fertilization and the young ones are born alive, but differ in that there is no placental connection and the unborn young ones are nourished by egg yolk; the mother's body does provide gas exchange (sharks and rays).
Ovoviviparous insects do not provide oxygen or nourishment to their developing eggs; they merely provide a safe brooding chamber for development. However, species of ovoviviparous fish, lizards, and snakes appear to provide some nutrition and oxygen to their developing progeny within the oviduct (although most nutrition is provided by the yolk of the eggs).
Like sharks, snakes also have three modes of gestation and birth - oviparity, viviparity and ovoviviparity. The fer-de-lance or terciopelo snake, for example, is viviparous.The offspring of this venomous snake are born alive; the mother can give birth to an average of 30 snakes after a pregnancy that lasts from 6 to 8 months.
The number of young born at a time depends on the species. Basking sharks are ovoviviparous and give birth to one or two live young. In the case of the garter snake, the young are born still enclosed in an amniotic sac but they escape it quickly.
Usually ovoviviparous species, such as some garter snakes and pit vipers, live in cooler climates where it would be harder for the mother snake to properly brood the eggs to keep them warm enough to hatch. By keeping them inside, she can maintain them at a comfortable temperature.
Ovoviviparous - note that the third letter is an 'o', not an 'i' - means producing young by means of eggs that are hatched within the body of the parent - as in some snakes.
Generally all snakes within the Viperidae family give live birth. The Viperidae family includes species such as pit vipers and rattlesnakes. These ovoviviparous snakes may carry the eggs inside their own stomachs for up to an entire year before laboring the baby snakes from their bodies.
Some species of snake are ovoviviparous and retain the eggs within their bodies until they are almost ready to hatch. Recently, it has been confirmed that several species of snake are fully viviparous, such as ...
20 most known ovoviviparous animals . Ovoviviparous are, in general, animals that are difficult to find in nature, although they predominate among some species of insects, molluscs and annelids, although several of the most common cases are among reptiles (as with The vipers, from which live offspring) and many varieties of fish.
