Viviparous Animals Example

What are viviparous animals?

They are known as viviparous animals, any animal that once it has been fertilized, develops normally within a process called gestation. This process will take place inside the womb of the mother that has been fertilized by a male animal. Since the natural process of gestation is completed, the moment of delivery arrives, thus the new animal is born.

As can be seen, they will belong to this type of animal, all those species that are develop from an embryo inside the mother's womb accompanied by a placenta that will be responsible for supplying the nutrients necessary for its normal development, in addition to the required oxygen.

The way in which an embryo will be produced inside the mother's womb is carried out through a process of fertilization from a sexual reproduction. The fertilization process occurs when the male deposits sperm in the womb and fertilization begins.

Differences between viviparous, oviparous and ovoviviparous animals:

Animals that are considered viviparous, tend to differ from the rest, by the form of reproduction that takes place. In the case of oviparous, this reproduction process will be carried out using an egg, where the new animal will be formed. Among the oviparous animals we can mention chickens and all kinds of birds.

In the case of ovoviviparous ones, the reproduction process is carried out through the egg, only that unlike oviparous ones, here, the egg will remain within the female's own organism. Examples of this type can be seen in snakes and other reptiles.

Gestation period:

It is important to bear in mind that in each type of animal, the process and duration of pregnancy is different in each case. Among the variants that intervene in the duration of gestation is the size of the animal, as well as the number of new offspring that can develop within the mother.

The truth is that in practically all cases, animals will develop within the mother's placenta so that the new member is fed with the nutrients that are in charge of administering the own placenta, until during gestation time, all the organs of the animal.

It was mentioned that in almost all animals this gestation process occurred, there are precisely some exceptions as is the case of kangaroos and koalas, which are part of the group of marsupials whose particular characteristic is that of not having a type of placenta rather, it is used for the culmination of the development of the young in a resource called the marsupial bag.

Man's gestation period.

What is viviparity?

This is the name given to the reproduction process that occurs in most animals, mainly mammals, although it also occurs in other species. The main function is to give birth at the culmination of the pregnancy stage, to the new offspring and to continue with the growth process being fed by the mother for another period so that the animal is finished developing, feeling protected by being close to the body of the mother.

Once the new calf reaches a stage of youth, and above all, they feel confident that they will be able to survive on their own alone, the time comes when they separate from the mother's body and develop instincts, starting with looking for food on their own own.

Characteristics of viviparity:

This type of animal has as its main characteristic the theme of investment of time and dedication that mothers are assigned to the new calf during the gestation process and once they are born, they continue with the careful. This is where another of the characteristics of this type of animal comes in and it is the fact that due to the time they dedicate to their children, they have few offspring at a time.
