Understanding Viviparous Animals
Viviparous animals are those that give birth to live young instead of laying eggs. This process involves the embryo developing inside the mother’s body, receiving nutrients and oxygen through a placenta or similar structure.
Examples of Viviparous Animals
- Human Beings: Humans give birth to live young after a gestation period of about nine months.
- Dogs: Dogs also give birth to live puppies, with a typical gestation period of around 63 days.
- Deer: Deer are viviparous and usually give birth to fawns, typically in the spring or summer.
Why Crocodiles Are Not Viviparous
- Egg-Laying Species: Crocodiles are oviparous, meaning they lay eggs. The female crocodile typically lays a clutch of eggs in a nest made of vegetation and soil.
- Development Outside the Body: The eggs incubate outside the mother's body, and the young hatch after a certain period, usually several weeks, depending on the temperature and species.
- Examples of Crocodilian Reproduction: After laying the eggs, the mother may guard the nest but does not provide nutrients to the developing embryos as viviparous animals do.
Conclusion
In summary, the correct answer to the question of which animal is NOT viviparous is option 'C', Crocodile. They reproduce by laying eggs, making them oviparous rather than viviparous.
