Adders (vipers) a type of snake. Also Boas and Vipers and Garter snakes
No. Most mammals give birth to live young, but the exceptions are the three species of monotremes - platypus, short-beaked echidna and long-beaked echidna. All species of bird lay eggs, rather than give birth to live young, and most amphibians, reptiles and fish also lay eggs. Some within each classification do bear live young.
Mammals reproduce by sexual reproduction, where a male mammal's sperm fertilizes a female mammal's egg. The fertilized egg then develops into an embryo inside the female's womb, where it is nourished through the placenta until birth. Mammals give birth to live young, as opposed to laying eggs like reptiles or birds.
well, dolphins actually don't lay eggs but give birth alive.
internal. horses give birth to live young - they're mammals.
Most reptiles lay eggs, but some species do not. An couple of examples of the latter would be the garter snake or all boas and all vipers. The eggs are fertilized inside the mother then hatch inside the mother then are born alive.
HatchedMost reptiles lay eggs and they hatch, however some snakes and lizards give birth to live young.In eggs.Birds,reptiles,amphibians,and fish are all born in eggs.Mammals are born alive.
Reptiles hatch from eggs.
Five reptiles that give birth to live young include the boa constrictor, garter snake, green sea turtle, viviparous lizard, and some species of skinks. Unlike most reptiles that lay eggs, these species exhibit viviparity or ovoviviparity, where the young develop inside the mother and are born alive. This reproductive strategy can provide advantages in certain environments, such as increased survival rates for the offspring.
