11 examples of OVOVIPAROUS reproduction: featured animals

The examples of ovoviviparous reproduction They are animals like him white shark, seahorse, the platypus, the boa constrictor... At unProfesor we tell you.

The ovoviviparous reproduction is the one that refers to those animals that reproduce through the formation of eggs inside the female's belly, where the embryo will mature until it is ready to hatch. It is then that the eggs are expelled from inside the mother's body and become independent beings.

In this lesson from a TEACHER, we want to explain to you, offer you examples of ovoviviparous animals so you can understand this complex concept of biology a little better. In addition, we are going to give you some examples of animals that reproduce in this way!

Before giving you examples of ovoviviparous reproduction, let's learn more about what this reproduction method consists of. The

This reproduction method It is quite common among species of invertebrates, but it is also the case in some species of reptiles and fish. In all these cases, fertilization occurs internally through copulation, with which the male introduces his genetic material inside the female.

Types of ovoviviparous reproduction: classification

Within ovoviviparous animals, we can make a more specific classification, taking into account the feeding method that embryos use inside the mother's body:

• On the one hand, we have embryos that feed only on the egg yolk in which they are developing.
• On the other hand, we can see animals that exhaust the yolk of the egg and begin to feed on it. maternal body.

Here we discover the differences between viviparous, ovoviparous and oviparous animals.

Let's put some on you examples of ovoviviparous animals, so that you understand a little better what the reproduction process of each of the species is:

• glass shingles (legless lizard): After 3 or 5 months of gestation, the female lays eggs with the mature young inside her, and hatching occurs immediately.
• White shark: It is another example of ovoviviparous reproduction. This shark does not lay eggs, but the babies hatch inside the mother and are then born fully developed.
• Limnonectes larvaepartus (frog): Its fertilization is internal and, once hatched from the egg, the tadpoles are expelled directly into the water by the mother's body.
• Boa constrictor: The hatching of the eggs occurs inside the mother's body, giving birth to already developed offspring.
• Seahorse: It is another example of ovoviviparous animals. In fact, it is a particular type of ovoviviparous, since the eggs do not mature inside the body of the female but in the body of the male. Fertilization occurs when the female passes the eggs to the male's sac.
• dogfish (small shark): The reproductive litter depends on the size of the female, since the usual is 1 to 20 embryos per gestation, but larger females can have larger litters. numerous. They are born outside the egg.
• Jackson Trioceros (chameleon): The young are born in litters of between 8 and 30 individuals, with a gestation period of up to six months.
• Stingray: It is another example of ovoviviparous reproduction. It is estimated that the time the eggs remain inside the female may be more than twelve months. They have one or two babies per litter.
• Suriname toad:Fertilization occurs outside the mother's body. Once fertilized, the female re-encloses the eggs in her body.
• Platypus: It is considered a mammal, but it lays eggs, so it can also be classified as ovoviviparous.
• Anaconda: In each litter, between 20 and 40 babies are born, approximately 60 cm long.

These are just some of the examples of ovoviviparous reproduction that will help you better understand our nature.

Now that we have seen some examples of ovoviviparous reproduction, it is interesting to complement our knowledge. And when we study animal reproduction methods in school, ovoviviparous reproduction is the most difficult to understand. A good way to make this concept clear is to see the characteristics that these animals have, in order to be able to identify them when you need to. These are the characteristics of ovoviviparous animals:

• Ovoviviparous eggs are many larger than oviparous and have a thinner shell. This allows that, when the female expels the eggs, the embryos can easily break the shell to go free into the environment.
• Fertilization of ovoviviparous animals is internal and the egg is kept inside the female's body, in a special duct found in her reproductive system.
• The fertilized egg is very more protected than those eggs that are laid and gestated outside.
• These animals do not lay eggs and then fertilize them, as birds do, but rather They fertilize her eggs inside from her body and they only expel them when the child is about to be born.
• The egg of ovoviviparous animals is located inside the body of the female, although there is no close contact between the embryo and the mother, as happens in viviparous animals, through the umbilical cord.
• The embryo develops within a shell egg from which you get all the nutrients you need. You may also need to obtain nutrients from the mother directly, as we mentioned in the first section of this lesson.

We hope this lesson has helped you understand a little better. ovoviviparous reproduction and you have seen some clear examples.
