Admin How are reptiles babies born?
While many reptiles lay eggs (oviparity), certain kinds of snakes and lizards give birth to live young: either directly (viviparity) or via internal eggs (ovoviviparity).
How do reptiles incubate their eggs?
Most megapodes scratch together mounds (sometimes astonishingly large) of vegetation or sand and lay their eggs inside. The heat for incubation is provided by decay of the vegetation, the sun, or (occasionally) volcanic activity.
Do reptiles have parental care?
In reptiles Reptiles provide less parental care than other tetrapods. When it does occur, it is usually female-only or biparental care.
What are those reptiles that give birth?
The viviparous lizard, or common lizard, (Zootoca vivipara, formerly Lacerta vivipara), is a Eurasian lizard. It lives farther north than any other species of non-marine reptile, and most populations are viviparous (giving birth to live young), rather than laying eggs as most other lizards do.
What happens when a reptile hatches?
Unlike amphibians, reptiles do not have a larval stage. Instead, newly hatched reptiles look like smaller versions of the adults. They are able to move about on their own, but they are vulnerable to predators. Even so, most reptile parents provide no care to their hatchlings.
What are reptiles how do they reproduce?
Reptiles reproduce sexually through internal fertilization; some species are ovoviviparous (lay eggs) and others are viviparous (live birth). Because of the development of impermeable, scaly skin, reptiles were able to move onto land since their skin could not be used for respiration in water.
How long are reptiles pregnant?
On average, temperate-zone reptiles have incubations or pregnancies of 8–12 weeks. Tropical species tend to have similar incubation periods; however, incubations of some species may last nearly one year or longer (as in the Fijian iguana [Brachylophus fasciatus]).
