What is the advantage of the viviparous animals?
Viviparity was one of the most significant evolutionary adaptations of vertebrate reproduction because it allowed offspring to develop within the body of the mother removed from predation and environmental pressures. In eutherian mammals, including humans, viviparity is dependent on the presence of a placenta.
What are the characteristics of viviparous animals?
The main characteristic of viviparous species is that embryo development occurs inside the maternal body. In live-bearing species, females invest and allocate higher energy resources to sustain larger size embryos than in oviparity.
What is the advantage of viviparous animals over Oviparous animals?
Answer: Explanation: Another important benefit of viviparity is the ability to reproduce at any time of the year. Unlike oviparous animals, which must produce yolk sacs when their food intake is the highest, viviparous animals can nourish their young with fat reserves.
What does it mean if an animal is viviparous?
1 : producing living young instead of eggs from within the body in the manner of nearly all mammals, many reptiles, and a few fishes. 2 : germinating while still attached to the parent plant the viviparous seed of the mangrove.
What is the benefit of oviparous?
The eggs that become fertilized in oviparous fish may spend long periods of time in the water column as larvae before settling out as juveniles. An advantage of oviparity is the number of eggs produced, because it is likely some of the offspring will survive.
Why are mammals called viviparous animals?
Viviparity is a form of reproduction found in most mammals and in several other species. Viviparous animals give birth to living young that have been nourished in close contact with their mothers' bodies. Humans, dogs, and cats are viviparous animals.
What do you mean by oviparous and viviparous animals?
Oviparous and viviparous are such two methods. ... This means oviparous animals lay eggs. These eggs develop and hatch into young individuals. In contrast, viviparous animals are born as live young individuals. Therefore, they do not lay eggs.
What are viviparous animals give two examples of viviparous animals?
The animals which give birth to young ones are called viviparous animals. Human beings and cow are examples of viviparous animals.
What is oviparous animal?
Oviparous animals are female animals that lay their eggs, with little or no other embryonic development within the mother. This is the reproductive method of most fish, amphibians, most reptiles, and all pterosaurs, dinosaurs (including birds), and monotremes.
What is the difference between oviparous animals and viviparous animals give two examples of each?
Oviparous organisms are those that lay eggs which can be either fertilised or unfertilised. Those animals that directly give birth to alive young ones are referred to as viviparous animals. ... Examples of oviparous organisms are birds, fish, insects, reptiles, amphibians. Mammals are viviparous animals.
Why are not all animals oviparous does being viviparous offer any advantage to organism?
All animals are not oviparous this is due to the fact that these have do not exhibit the capability to lay the eggs. The vivipary animals have the advantage that is fertilization takes place within the female body thus the embryonic development is safe within the mothers womb.
Why are humans viviparous?
Humans, like most mammals, are viviparous animals. Humans reproduce via internal fertilization. As in all higher mammals, the egg implants in the uterine wall while it develops. ... Unlike some viviparous animals, humans are born well before they are fully developed.
What is viviparous fish?
Viviparous fish are fish which give birth to live young, the eggs develop whilst receiving nutrition from the parent.
Which is oviparous mammal?
Platypus (Ornithorhynchus) and Echidna (Tachyglossidae) are oviparous mammals.
What are oviparous animals give examples?
Oviparous animals look after their eggs after laying them. Some viviparous animals show parental care after birth, while others don't. Examples of oviparous animals include frogs, snakes, lizards, hens, duck, fishes, shark, penguins, butterflies, octopus, etc.
