7 Difference between Oviparous and Viviparous Animals with Table

What is the difference between oviparous and viviparous animals?

Zoology is a branch of biology that deals with the study of animals. Oviparous and viviparous are some examples of these animals.

The article provides detailed insights into the difference between oviparous and viviparous animals in points as well as a comparison chart.

Difference between Oviparous and Viviparous Animals

What Are Oviparous Animals?

Oviparous animals refer to animals that lay eggs that mature and hatch after being expelled from the body. The development of the eggs takes place inside the mother’s body.

These types of animals can either undergo internal or external fertilization. Ovoviviparous is a term that describes the type of fertilization scientifically.

Examples of oviparous animals are frogs, sharks, snakes, birds, and insects. The chances of young ones to survive are minimal.

What Are Viviparous Animals?

Viviparous animals refer to those animals that give birth to a developed live young individual. The development of the zygote takes place inside the female womb.

The type of fertilization experienced by these animals is internal fertilization. The developing embryo receives nutrients from the mother.

Examples of viviparous animals are cats, dogs, humans, elephants, lions, tigers, etc. the chances of young ones to survive is quite high.

Comparison Chart: Oviparous Vs Viviparous Animals

Basic Terms	Oviparous	Viviparous
Definition	Refers to egg-laying animals that mature and hatch after being released from the body	Refers to animals that give birth to the young ones
Correspondence	Lay either fertilized eggs or unfertilized eggs	Give birth to live young individuals
Type of Fertilization	Either internal or external fertilization	Typically internal fertilization
Development of the Zygote	Occur outside the female	Occur inside the female
Nourishment of the Embryo	Get nutrients from the York	Get nutrients from the mother
Chances for Survival	Quite low	Quite high
Examples	Birds, reptiles, amphibians, most fish, insects, mollusks, arachnids, and monotremes	Mammals like cow, dogs, goat, zebra, donkey, elephant and cats

Differences between Oviparous and Viviparous Animals

Viviparous give birth to young ones whereas oviparous lay either fertilized or unfertilized eggs which hatch to young ones

The development of zygote in oviparous take place outside the female while it takes places inside the female of viviparous

The chances of young ones of oviparous to survive are less while that of viviparous is quite high

The embryo of viviparous get nutrients from the mother while that of oviparous from the York

The type of fertilization in viviparous is internal while that of oviparous is either internal or external

The correspondence of viviparous is giving birth to develop and live young individuals while oviparous lay either fertilized or unfertilized eggs

Examples of viviparous are cats, dogs, humans, elephants, lions, and tigers while oviparous are amphibians, fish, reptiles, birds, and insects.
