Ciri-ciri Hewan yang Berkembang Biak dengan Cara Vivipar Adalah

>Hello Sohib EditorOnline, in this article we will discuss the characteristics of animals that reproduce through viviparity. Viviparity is a type of reproduction in which the offspring develop inside the mother’s body and are born alive. This method of reproduction is common in mammals, but can also be found in some reptiles, fish, and invertebrates.

What is Viviparity?

Viviparity is a type of reproduction in which the offspring develop inside the mother’s body and are born alive. This is different from oviparity, in which the offspring develop in eggs outside the mother’s body. Viviparity is common in mammals, but can also be found in some reptiles, fish, and invertebrates.

The advantages of viviparity include better protection for the offspring and the ability to nourish the developing embryo through a placenta or other specialized structures. However, viviparity also requires more energy from the mother and limits the number of offspring that can be produced at one time.

Characteristics of Animals that Reproduce through Viviparity

Animals that reproduce through viviparity have several distinct characteristics:

1. They have internal fertilization: Viviparous animals mate internally, which allows for the fertilization of eggs inside the female’s body.
2. They develop inside the mother’s body: After fertilization, the embryo develops inside the mother’s body, often in a specialized structure such as a placenta or yolk sac.
3. They are born alive: Unlike animals that reproduce through oviparity, viviparous animals give birth to live offspring.
4. They have fewer offspring: Because viviparity requires more energy from the mother, viviparous animals typically give birth to fewer offspring than oviparous animals.

Examples of Viviparous Animals

While most viviparous animals are mammals, there are several other types of animals that reproduce through viviparity as well:

Animal Type	Example
Mammals	Dogs, cats, whales, humans
Reptiles	Snakes, lizards, turtles
Fish	Sharks, rays, some bony fish
Invertebrates	Some insects, spiders, scorpions

Mammals that Reproduce through Viviparity

The majority of animals that reproduce through viviparity are mammals, which are characterized by their ability to nurse their young with milk produced by mammary glands. Some examples of viviparous mammals include:

Dogs

Dogs are a common example of a viviparous mammal. Female dogs typically give birth to litters of puppies after a gestation period of around 63 days. Dogs are able to nurse their young with milk produced by mammary glands for several weeks after birth.

Cats

Cats are another common example of a viviparous mammal. Female cats typically give birth to litters of kittens after a gestation period of around 65 days. Cats are able to nurse their young with milk produced by mammary glands for several weeks after birth.

Whales

Whales are the largest mammals on Earth and are also viviparous. Female whales have a gestation period that can last up to 18 months, and give birth to a single calf at a time. Whales nurse their young with milk produced by mammary glands for several months after birth.

Humans

Humans are also viviparous mammals. Female humans have a gestation period of around 9 months, and give birth to a single baby at a time. Humans are able to nurse their babies with milk produced by mammary glands for several months after birth.

Reptiles, Fish, and Invertebrates that Reproduce through Viviparity

While mammals are the most well-known viviparous animals, there are several other types of animals that reproduce through viviparity as well:

Snakes

Some species of snakes reproduce through viviparity. Female snakes carry their eggs inside their body until they are ready to hatch, and then give birth to live offspring. This method of reproduction is common in vipers and pit vipers.

Turtles

Some species of turtles also reproduce through viviparity. Female turtles carry their eggs inside their body until they are ready to hatch, and then give birth to live offspring. This method of reproduction is common in sea turtles.

Sharks and Rays

Many species of sharks and rays reproduce through viviparity. Female sharks and rays carry their eggs inside their body until they are ready to hatch, and then give birth to live offspring. This method of reproduction is common in species such as great white sharks and manta rays.

Insects, Spiders, and Scorpions

Some species of insects, spiders, and scorpions also reproduce through viviparity. Female insects and spiders carry their eggs inside their body until they are ready to hatch, and then give birth to live offspring. This method of reproduction is common in species such as cockroaches and tarantulas.

FAQs

1. What is the difference between viviparity and oviparity?

Viviparity is a type of reproduction in which the offspring develop inside the mother’s body and are born alive, while oviparity is a type of reproduction in which the offspring develop in eggs outside the mother’s body.

2. What are the advantages of viviparity?

Viviparity provides better protection for the offspring and allows for nourishment from the mother through specialized structures such as a placenta or yolk sac.

3. What types of animals reproduce through viviparity?

Animals that reproduce through viviparity include mammals, reptiles, fish, and invertebrates.

4. How do viviparous animals mate?

Viviparous animals mate internally, allowing for the fertilization of eggs inside the female’s body.

5. How many offspring do viviparous animals typically have?

Because viviparity requires more energy from the mother, viviparous animals typically give birth to fewer offspring than oviparous animals.

Conclusion

In conclusion, viviparity is a type of reproduction in which the offspring develop inside the mother’s body and are born alive. This method of reproduction is common in mammals, but can also be found in some reptiles, fish, and invertebrates. Viviparous animals have several distinct characteristics, including internal fertilization, development inside the mother’s body, the birth of live offspring, and fewer offspring produced per pregnancy. Understanding the characteristics of viviparous animals is important for understanding the diversity of life on our planet.
