Viviparous Animals

Animals reproduce in their own way. There are 3 ways of reproduction from animals, namely: laying eggs, laying eggs and giving birth, giving birth or giving birth. In this discussion we will learn about the definition of viviparous animals, characteristics, and examples of animals that can give birth.

Definition of Viviparous Animals

Viviparous animals are all types of animals that have offspring by giving birth called viviparity. Eggs or fetuses grow and develop in the mother’s womb, and get their food through the mother’s food reserves. After that, a new offspring of the animal species is born, and the female parent will suckle and feed the newly born offspring.

Difference between Viviparous Animals with Oviparous, and Ovoviviparous

The presence of various types of animals also have differences in the way they reproduce.

Vivipar Oviparous Ovoviviparous
Childbirth / Childbirth Lay eggs Egg-laying and Egg-laying

The table above explains that the way animals reproduce is grouped into 3 ways. Both from amphibian species, as well as mammals, and others. Groups of mammals usually get offspring by giving birth.

Characteristics of Viviparous Animals

There are certain characteristics in animals that reproduce viviparously, and these characteristics are:

  • Usually a group of mammals.
  • There are auricles in viviparous animals.
  • There are mammary glands.
  • The body is covered with hair or fur.
  • Hot blooded.
  • Have different periods of pregnancy.
  • The body shape of the newborn offspring is the same as the parent.

Groups of mammals usually have offspring in a viviparous way, and the auricles they have are useful as a signal for the origin of sound. The mammary glands in viviparous animals function to suckle their offspring or offspring.

The gestation period for viviparous animals varies depending on the animal species, for example, rabbits are pregnant for 3 days, and cows have a longer gestation period, around 280 days.

In addition to the characteristics mentioned above, animals that give birth have 2 ways of reproducing, namely: generative or vegetative. The process of generative conception means that there is a sexual process (marriage of female and male parents). Meanwhile, through vegetative means there is no marriage or asexuality.

Examples of Viviparous Animals

Learning about viviparity will be clearer and understandable if you know examples of any animal, along with pictures of the animal.

Here are 20+ examples of animals that will be explained about how they reproduce, namely:

1. Cat

How cats reproduce after meeting the egg and sperm, namely:

→ Zygote. The zygote grows and develops in the womb of the female parent.

→ Embryo. The period of pregnancy for 60 days to 67 days.

→ Give birth to kittens.

After the birth of a new breed, the kitten is breastfed by the female mother.

2. Dog

Dogs also include animals that reproduce by giving birth. The mating age of these animals usually occurs between the ages of 6 months to 12 months. The reproductive cycle in the female parent is 2-4 weeks with maturity between 8 months to 18 months. However, the age of sexual maturity varies, depending on the taste or species of the dog.

3. Cow

Cows are mammals , which means they are also one of the characteristics of viviparous animals. When pregnant, the cow’s weight will increase, and it will also have large horns. That’s what can produce a lot of milk, so that they can breastfeed their children.

4. Buffalo

The maturity of the buffalo is around 2 years to 3 years. The nutritional quality of buffalo food can affect the age of maturity. Female buffalo mating with males usually occurs at night.

The gestation period is 9 months to 11 months. During one pregnancy can get 1 or even 2 offspring. The calves will be breastfed until they are 1 year old.

At the age of 3 years, the calf will mingle with other groups, and begin to separate from the mother.

Buffalo animals that are usually bred are adult buffalo, aged about 25 years.

5. Monkey

Monkeys or commonly called monkeys reproduce by giving birth. Pregnancy period for 6 months. After 6 months, and giving birth to the monkeys, the monkeys look for food by jumping from one tree or branch to another.

6. Elephant

This large animal reproduces in the same way as the animal examples above. The difference lies in the relatively long gestation period because it is up to 18 to 22 months.

Characteristics of elephants when ready to mate, namely:

  • He wags his ears more often. The goal is that female elephants are more tempted and interested in mating.
  • Male elephants mate at an old age of around 40 to 50 years.
  • The female elephant is ready to mate at the age of 14 years.

The elephant’s reproductive organs are different from other mammals (the testes are located in the body near the kidneys). The duct is 2 meters long, and begins to produce sperm between the ages of 10 and 15.

7. Whale

The maturity size of the male whale is 8 meters to 9 meters, while the female whale has a length of 10 meters. Calves are ready to be born around the age of 50 cm, and once gave birth to hundreds of offspring of calves.

8. Dolphins

Dolphins are considered mature or sexually mature at the age of 7 years to 9 years. There is a separate breeding season for the dolphins or freshwater dolphins, which is from December to June.

The gestation period is 14 months, and only gives birth to 1 offspring every 2 years or even every 3 years. When the calf was born, the child was about 1 meter long and weighed 10 kg.

The baby dolphins are weaned at the age of 2 years, and the age of the dolphins ends around the age of 30 years. This is what causes the dolphin fish to be threatened with extinction.

9. Tiger

These carnivorous animals reproduce by giving birth to their children. The gestation period is about 2 months or more or 100 days. The cub will cling to its mother for 2 years.

The breeding season for this rare animal occurs from July to August. Give birth to 3 to 5 offspring, with the same skin color as the mother’s, it can be even darker or darker.

10. Lion

This king of the jungle has characteristics as a viviparous animal, which has ears, mammary glands, and can suckle their children.

Characteristics of lions when in mating, namely:

  • Takes 20 seconds for copulation (sexual intercourse).
  • A day can mate 50 times.
  • The length of pregnancy of the female parent takes 98 days to 120 days.
  • The female leaves the group temporarily while she is still in her pregnancy (until the chicks are about 6 to 8 weeks old).
  • Give birth to 1 to 6 lion cubs.
  • Weaned at the age of 7 months to 10 months.
  • In the first week the baby lion can not see.
  • Week 3 can run.

In addition to the examples of animals mentioned above, there are many other animals that reproduce by giving birth, such as:

  • Camel
  • Bat
  • Giraffe
  • Sea lions
  • Koala
  • Horse
  • Goat
  • Codot
  • Rat
  • Orangutan
  • Squirrel

More than 20 examples of viviparous animals have been presented so that they can be useful for all who want to learn about how animals reproduce, and give birth to offspring every period or at a certain mating period.
