Do all animals give birth to live babies?
Many animal groups have some species that lay eggs and others that birth live young, including fish, amphibians, and yes, even mammals, says Whit Gibbons, evolutionary biologist at the University of Georgia's Savannah River Ecology Laboratory.
Why do birds lay eggs instead of giving birth?
But baby birds and turtles are stuck cracking open eggshells. Oviparous animals produce eggs that hatch after leaving the mother's body. ... The theory suggests that bird embryos get more air and develop into healthier chicks laying in a nest than they would inside the mother's body.
Why do only some snakes give live birth?
Viviparous
Viviparous snakes give birth to live young. There are no eggs involved at any stage of development. In this case, the snakes nourish their developing young via a placenta or yolk sac, something that's unusual among reptiles.
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).
What animal doesn't lay eggs?
Birds, insects, reptiles and fishes are oviparous animals. Animals which reproduce by giving birth to their young ones are called viviparous animals. These animals do not lay eggs. Mammals like cat, dog and man are viviparous animals.
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 snakes give live birth?
Answer: No! While snakes are known for laying eggs, not all of them do so! Some do not externally lay eggs, but instead produce young by eggs that are hatched internally (or inside) the body of the parent. Animals that are able to give this version of live birth are known as ovoviviparous.
Are fish born alive or hatched?
Fish Reproduction: The eggs of fish are fertilized either externally or internally, depending on species. The female usually lays the eggs, and the embryos in the eggs develop and hatch outside her body. ... Each embryo develops in its own egg. The young are 'born alive' like most mammals.
How do chickens get pregnant?
The yolk is created in the ovary and, when ready, gets ejected into the first part of the oviduct, called the infundibulum. This is where fertilization takes place if the hen has mated. After mating, the sperm of the rooster travels to the infundibulum, where it fertilizes the newly released yolk from the ovary.
Do birds pee?
Birds brighten our lives. ... The answer lies in the fact that birds, unlike mammals, don't produce urine. Instead they excrete nitrogenous wastes in the form of uric acid, which emerges as a white paste. And uric acid doesn't dissolve in water easily.
Do anacondas give live birth?
Unlike most snake species, anacondas don't lay eggs. They have live births.
Is live birth better than laying eggs?
Giving birth to living young allows the female to better protect her developing embryo until it's ready to be born. ... Females that give birth usually have smaller broods than their egg-laying counterparts. Giving birth to live animals provides protection inside the mother's body from heat, cold, moisture and predators.
Do snakes give birth through their mouth?
There is a common misconception that snakes give birth through their mouths. This is not true: Snakes do not give birth through their mouths. However, not all species of snakes give birth the same way. The way that a female snake delivers her babies depends on the species of snake.
