Animals Directory

Archive for the ‘Reptiles info’ Category

Are all those animals that reproduce by eggs, including in this category, the vast majority of insects, reptiles, amphibians, fish, birds and all species of mammals known as “Remonstrate “(like the platypus and Chicana).

These eggs can be placed in dry, damp or in the mother (viviparous). For dry environments, the egg is fertilized in the time of post. This does not happen in the case of wet environments, where the eggs are not fertile yet, and once placed in water, the male sheds his sperm over them, completing fertilization. In the case of viviparous, the eggs develop and hatch inside the mother’s body, leaving your body to live young.

The vast majority of the eggs are very fragile and have a good chance of food for predators, so parents are oviparous jealous of their unborn babies and their caregivers cautiously, especially in the case of birds, where this aspect is very root. Not so in the case of some species of reptiles (like rattlesnakes), which may have attitudes of cannibalism, eating their own eggs.
The moment where he breaks the egg and the baby is born from within, is called hatching, and represents the birth of the baby.

Note that in the prehistoric age, the first animals on earth (fish) are reproduced in this way and 450 million years ago, the first mammals appeared only 180 million years ago, ie about 270 million years later.
