A large number of animals produce eggs for reproduction.
Some eggs have a leathery or hard shell to protect them from the elements and from the handling they receive during incubation.
Some eggs, like those of most amphibians are soft and rely on water for hydration.
Other eggs remain in a protected, uterine environment where they grow until birth.
Eggs which were not fertilized will turn white, usually within the first day. After that, it is unavoidable that some eggs will die during the development process, but the number can be reduced by maintaining proper water flow over the eggs (if you have removed the eggs from the parents) and treating the water with some fungicide such as MarOxy.
Simply because snake eggs are less likely to be eaten by predators. Frogs eggs, floating in water, are potential food for anything that can get to it. Therefore - if a frog lays hundreds of eggs, there's more chance of at least some of them hatching into tadpoles.
Less than half of the eggs turn into tadpoles in frog reproduction because many of the eggs are not fertilized by sperm. Additionally, some of the fertilized eggs may not develop properly due to genetic abnormalities or environmental factors. Only the healthiest and most viable eggs will successfully develop into tadpoles.
Some birds do lay eggs even if they haven't mated. Don't know if Penguins do that too. But to lay fertile eggs - eggs that turn into chicks and hatch - they have to mate first.
They turn their eggs so they can be heated evenly on all sides.
no they lay eggs THEY DON'T!! but some chickens lay eggs that turn into chicks over time
Vampires mostly turn into bats but there are some sources which have them able to turn into other animals - wolves, rats, spiders...
first you turn switch 4 then turn switch 2 then turn switch 3 then turn switch 1
No animals can "turn themselves into other animals".
Well I say no I have 8 eggs and never turn into one.
Yes. They can even lay eggs and mate.
No. Earthworm eggs turn into earthworms.
