A anaconda is viviparous so they give birth to live young. I would say they are boas.

A little off topic, but wouldn't it be ovoviviparous?

Vivipary
From Wikipedia, the free encyclopedia

A viviparous animal is an animal employing vivipary: the embryo develops inside the body of the mother, as opposed to outside in an egg (ovipary). The mother then gives live birth. The less developed form of vivipary is called ovoviviparity, which, for instance, occurs in most vipers. The more developed form of vivipary is called placental viviparity; mammals are the best example, but it has also evolved independently in other animals, such as in scorpions, some sharks, and in velvet worms. Viviparous offspring live independently and require an external food supply from birth. Certain lizards also employ this method such as the Genus Tiliqua and Corucia. The placenta is attached directly to the mother in these lizards which is called viviparous matrotrophy

But doesn't the female carry the eggs inside of her until they hatch?

Like Vipers do as your reference says.

I'm not sure, I always thought ovoviviparous was like a Arabian Sand boas-thing.

From wikipedia:

Ovoviviparous animals develop within eggs that remain within the mother's body up until they hatch or are about to hatch. This strategy of birth is known as ovoviviparity. It is similar to vivipary in that the embryo develops within the mother's body. Unlike the embryos of viviparous species, ovoviviparous embryos are nourished by the egg yolk rather than by the mother's body. However, the mother's body does provide gas exchange.


Sand Boas are ovoviviparous.

I'm going to do some more gooooogling :D

Yeah, they are ovoviviparous, they have proper eggs that develope inside of them and are born live.
Life is but a glimpse of triumph amongst incomprehensible failure.

viviparous is acceptable we use it in scientific literature. (confused now?)
