Understanding Viviparous Animals
Viviparous animals are those that give birth to live young instead of laying eggs. This reproductive strategy is common among mammals, including humans and dogs.
Examples of Viviparous Animals
- Dog: The correct answer is option 'C' - Dogs are viviparous, meaning they carry their young in the womb until they are fully developed and ready to be born.
- Fish and Frogs: These animals primarily reproduce through external fertilization, laying eggs in water. While some species of fish have evolved to give live birth, the majority are oviparous (egg-laying).
- Birds: Birds are also oviparous, laying eggs that develop outside the mother's body.
Key Characteristics of Viviparity
- Live Birth: Viviparous animals give birth to live young, which have developed within the mother's body.
- Nourishment: The developing embryos receive nutrients and oxygen through a placenta or similar structure.
- Parental Care: Viviparous species often show a higher degree of parental care, enhancing the survival chances of their offspring.
Conclusion
In summary, the dog is a prime example of a viviparous animal due to its method of giving birth to live young. In contrast, frogs, fish, and birds primarily reproduce by laying eggs, making them oviparous. Understanding these reproductive strategies is essential in the study of animal biology and evolution.
