What is oviviparity?
ovoviviparity is a method of developing animals in which young people grow in eggs inside the body of the mother and the mother gives birth to young. Ovoviviparity is seen in some fish, reptiles and amphibians around the world. There are a number of reasons why animals could develop in order to give birth in this way, and ovoviviparity is a topic among scientists. This method of reproduction is also interesting for many laymen, because most people assume that egg layers cannot give birth to live young. For example, people are vivipar animals. On the contrary, ovoparity in which the animal puts eggs and young hatching is a method of reproduction used by many birds, plasimi, amphibians and others. Ovoviviparity is a mixture of the method and it is much more rare.
The primary difference between ovoviviparity and vivipar other than obviously the presence of eggs is that ovoviviparous animals do not provide nutrition to their young through placenta, such asThis is in viviparous animals. Instead, developing young people feed on egg yolk, as well as their wrapping cousins. The mother's body provides egg protection, allowing them to develop without the risk of being consumed or trampled by other animals, and also provides some gas exchange for developing eggs.
The advantage for the wrapping is that animals can lay large clutches of eggs and ensure that at least some of their young survive. Ovoviviparous Animals can only incubate a limited number of eggs at the same time, usually giving birth no more than six young people. Therefore, young are more rare for their parents. Unlike Vivipar's animals, Ovoviviparous Young, they are usually also very well developed and premature, capable of navigating the world shortly after birth, although they may still require instructions from their parents.
In some animals, young animals were born in larval form and turn over their parents' bodies. Others are born fully formed even if they may be requiredVat for several weeks or months to ripen to the size of their parents. Sharks are among the most important animals that exhibit ovoviviparity, although there are many other examples in fish, reptiles and amphibian, including the rays of the manta, viper and some toads.
