Viviparous animals: Animals that give birth to live offspring (i.e., babies) are called viviparous animals. Depending on the type of propagation, the animals have split into two- oviparous and viviparous animals.

Answer: Reproduction is an important process which is responsible for the continuity of life on the planet earth. The animal kingdom has species undergoing the process of fertilization in two ways – one where fertilization takes … Oviparous animals The offspring’s development occurs outside their mother, and this form of reproduction greatly favors the survival of the species. Given that oviparous animals lay eggs on the environmental surface the chances of survival are less because the eggs are highly susceptible to predators and vagarious of nature. • Viviparous animals reproduce by giving birth to young ones, which are fed by the secretions of the mammary glands. In oviparous animals, the Embryo's primary source of nutrition lies in the yolk material inside the eggshell, which is solely deposited by the mother’s reproductive system.

Oviparous definition, producing eggs that mature and hatch after being expelled from the body, as birds, most reptiles and fishes, and the monotremes. In general, animal reproduction can be divided into two methods: Oviparous and Viviparous. Viviparous In this strategy, one or many eggs can be produced. In many species, the male supplies his gamete in the form of sperm, which must find its way to the egg. • Viviparous animals show internal fertilization, whereas oviparous animals primarily show external fertilization, but some are partially internal. Viviparity, on the other hand, refers to giving birth to young ones directly. Fertilization is the phenomena, part of life process – reproduction where male and female gametes unite forming a structure known as zygote which eventually develops into the foetus.

Viviparous Animals, Oviparous Animals & Ovoviviparous Animals In the animal kingdom, external fertilization is a type of fertilization where the sperm-egg fusion takes place externally, outside the female body. Being oviparous is an evolutionary strategy for reproduction. The main difference between oviparous and viviparous animals is the method of the development of the young ones. Explain briefly about female reproductive system. a) Iam formed by the fusion of male and female gametes. Such a condition is known as ‘Lecithotrophic,’ unlike matrotrophic. Give Example? a) Iam a gamete that has tail and travel to fuse with female gamete. Ovoviviparous animals have the embryos develop inside eggs that remain in the mother's body until they are ready to hatch. The theory is that some oviparous animals tend to develop eggs longer than others internally. Mammals like cow, horse, dog, cat, and human beings are examples of viviparous animals.
