Do all animals have live birth?
It is not only mammals that give birth. Some reptiles, amphibians, fish and invertebrates carry their developing young inside them. Some of these are ovoviviparous, with the eggs being hatched inside the mother's body, and others are viviparous, with the embryo developing inside her body, as in the case of mammals.
What kind of animals give birth to live offspring?
Mammals give birth to live young, are warm-blooded (can regulate their own body temperature) and are vertebrates with internal skeletons. Monotremes are mammals that lay eggs rather than bear live young.
What animal does not lay eggs or give birth?

Why do humans not give birth to as many babies as frog do?
frogs reproduces more because there is one father but the number of mothers are more because there could be any number of females that can be fertilized whereas in humans internal fertilization takes place so the sperm can only fertilize one egg.
Do Frogs give live birth?

Why do animals give birth to babies that look like them?

What are the 5 mammals that lay eggs?
Only five species of animals share this extraordinary egg-laying trait: the duck-billed platypus, western long-beaked echidna, eastern long-beaked echidna, short-beaked echidna, and Sir David's long-beaked echidna. All of these monotremes are only found in either Australia or New Guinea.
What percent of animals lay eggs?
That being said, the short answer to your question is that more than 99 percent of the world's animals reproduce by laying eggs. Live-bearing examples occur among many animal groups, but the phenomenon seems common to us because of mammals: the most conspicuous animals that are almost exclusively livebearers.
Do chameleons give live birth?
Offspring. Chameleons are different from many reptiles because some of the species, like the Jackson's chameleon, have live births. These species can give birth to eight to 30 young at one time after a gestation of four to six months. While the young are born live instead of in an egg, they started as an egg.
Do any male animals lay eggs?
Seahorses, and their close relatives – pipefish and seadragons – belong to the scientific family Syngnathidae. While male seahorses are the only ones that hold developing eggs in a true pouch, male pipefish and seadragons carry developing eggs attached to an area on the underside of their bodies.
Do sharks give live birth?
There are over 500 species of shark living in waters around the world and the majority give birth to live young. The remainder are oviparous, meaning they lay eggs. ... Among them are egg layers such as the small-spotted catshark (Scyliorhinus canicula) and nursehound (Scyliorhinus stellaris).
