Ovoviviparous Animals

The reproduction of living things is different, based on their reproductive system. Humans give birth by way of, while animals have various ways to reproduce. One way of animal reproduction is Ovoviviparous. Ovoviviparous animals produce offspring by laying eggs and also giving birth.

Definition of Ovoviviparous Animals

The definition of ovoviviparous animals is a type of animal that reproduces by laying eggs and giving birth. Embryos of ovoviviparous animals develop inside the egg. The eggs remain in the female parent’s body until the eggs hatch. If the eggs hatch, the female parent will give birth to new offspring or offspring.

Characteristics of Ovoviviparous Animals

  • Sexual or sexual reproduction system to produce a zygote.
  • The zygote gets the food reserves in the egg.
  • The embryo develops inside the egg.
  • Eggs develop inside the female parent’s body.
  • The eggs hatch inside the female parent’s body.
  • Not breastfeeding.
  • Cold blooded animals.

Ovoviviparous animals do not have special characteristics, it’s just a different way of breeding, namely laying eggs and giving birth. In order to understand more clearly about ovoviviparous, study the examples below.

Examples of Ovoviviparous Animals

There are various types of ovoviviparous animals that reproduce by giving birth and laying eggs below, which come from different species based on their diet, body shape, and other characteristics.

1. Guppies

Guppies are one of the most well-known freshwater fish species because they adapt easily and quickly to spawning and giving birth. Breeding of guppies takes 21 or even 30 days. This happens because of the temperature of the water where the fish are located.

2. Stingray

Another example of an animal that can lay eggs and give birth is the stingray. Stingray has its own unique characteristics because it only takes 90 seconds for the fertilization process, but the breeding time is completed within 9 months to 12 months.

3. Shark

Sharks are one of the fiercest and most feared predators in the marine ecosystem. This happens because its large body size preys on the flesh of small fish in front of it. There is no complete reference for the breeding period of this predatory fish, but the method of breeding is the same, namely laying eggs and giving birth.

4. Salamander

How to breed amphibian species (a group of animals that have a backbone or vertebrates ) are:

  • Internal fertilization (male salamanders release sperm in a spermatophore sac ). Spermatophores have 80 to 100 sperm, but the sperm produced depends on the season.
  • Female Salamander inserts the sperm into the body
  • Fertilization of a sperm cell and an egg cell occurs
  • Give birth to a fertilized egg
  • Hatching a child

This type of amphibian group looks similar to a lizard, which is 4 feet of the same size, has a short nose, and a long tail, and a slender body.

5. Lizard

Some types of ovoviviparous animals such as lizards reproduce by oviparity or lay eggs, but some of these lizard species can reproduce by giving birth. This happens because the habitat and species are different.

Lizards reproduce sexually (require a partner or reproduce by mating), and asexually (reproduce without a partner).

6. Seahorse

The 6th ovoviviparous example is the seahorse. Seahorses, one of the male animal species, can become pregnant. The pregnancy of the male parent is due to the presence of a kangaroo-like sac in his body. The sac is used to store and develop egg cells.

The fertilization process is:

  • The female mother’s reproductive system is mature
  • Ready to distribute to the male’s mother’s pouch
  • Eggs are stored in the male’s mother’s sac

The number of eggs produced is 50 to 200 eggs in one pregnancy, and the number of eggs produced depends on the age of the seahorse.

8. Chameleon

Animals that are known for their color that can change according to the color of the place they are stepping on are chameleons. The color change in the animal is a technique to trick the enemy. Some chameleons reproduce by laying eggs or by being oviparous .

8. Sea Wreck Snake

Dead sea snakes are also known as green snakes because their skin is green, and the venom of sea carcasses is very dangerous. This snake species is included in the ovoviviparous category because it reproduces by laying eggs and giving birth.

9. Platypus

Platypus is an ovoviviparous animal species originating from Australia, but the habitat of this animal can be found in several other areas. In addition to ovoviviparous breeding, platypus are also classified as animals that can reproduce by laying eggs or oviparous animals .

Platypus reproduction process:

  • Fertilization occurs.
  • The embryo develops in the egg.
  • Take nutrients from egg yolks.
  • Embryo reproduction takes 10 to 14 days in the womb

10. Iguanas

Another lizard species of the Ovoviviparous group is the Iguana. Its original habitat is in tropical areas such as South America and Central America, as well as the Caribbean islands.

The female parent who is mature and healthy does not need to mate or fertilize in the absence of a male parent.

  • Females become adults between the ages of 2 and 4 years in green iguanas.
  • Follicles (sacs of fluid to form eggs) develop in the ovaries.
  • Fast for 3 weeks to 6 weeks before laying eggs. This is because the stomach will be full of eggs and the stomach is compressed, leaving less space to receive food in the stomach.

11. Anaconda

Anaconda is a species of snake that can wrap around prey very strongly and move quickly. The characteristics of breeding in this type of anaconda snake are:

  • Mating in certain seasons.
  • The female parent is more aggressive during the mating season.
  • The baby yield is about 20 to 100 baby snakes.

12. Boa

In general, boas come from reptile animal species that reproduce oviparously , but some of these animals can reproduce by laying eggs and giving birth or viviparous animals .

Boas are ready to mate from the age of 2 years, and when mating season arrives, boas are more aggressive. Boa produce 10 to 40 snake eggs in one pregnancy. Estimated gestational age is 6 months.

13. Crocodile  

Crocodiles are an example of an ovoviviparous animal. Crocodiles also include reptiles, and also carnivores or carnivores .

14. Kadut Snake

Snakes are generally ovoviviparous, but this type of snake can only survive in water. This happens because it will cause the skin to tear, and it will be difficult to move if it is on the ground.

15. Snake Sapphire

 

Shoot snakes are still classified as harmless ovoviviparous reptiles, because their venom is too weak, but quite deadly for their prey, such as small birds and frogs. The shoot snake is also an example of an ovoviviparous animal that reproduces.

Mako sharks, geckos and lizards, as well as pythons, and Komodo dragons are also included in Ovoviviparous members because they can lay eggs and also give birth. An explanation of animals that reproduce by these 2 methods has been described through understanding, and characteristics, as well as examples and pictures of these ovoviviparous animal species.
