What reptile is born alive?

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 is named for the fact that it is viviparous, meaning it not only lays eggs, but also gives birth to live young.


Are fishes born alive or in eggs?

Fish reproduce by bearing live young or by laying eggs. Livebearers give birth to fully formed and functional young called fry. The eggs are fertilized and hatch within the female.

Are birds born alive or in eggs?

No bird gives birth to live young. Birds quickly form and lay an egg covered in a protective shell that is then incubated outside the body. Birds developed much great mobility than a mammal, but at the cost of being unable to carry its growing offspring about in its body.

What are baby crocs called?

Do crocodiles have brains?

Crocodilians: Natural History & Conservation: Crocodiles, Caimans, Alligators, Gharials. They say crocodiles have small brains. Indeed they do, but crocs are not simple-minded. They display complex social behaviour, including communication, cooperation and parental care, and they are extremely good at learning.

Is it true crocodiles can live forever?

It may be tempting to think of these big reptiles as totally alien to us humans, but the truth is they live a lot like you do: they grow up quickly, reach full size, gradually get older and weaker, and eventually die (after what was hopefully a long – but not endless – life).

How did crocodile lay eggs?

Crocodilians are either hole nesters or mound nesters. That is, they either excavate a hole, usually in sand, and bury their eggs, or they construct a mound, usually out of vegetation, and deposit their eggs in the centre of it.


Do male crocodiles lay eggs?
