Oviparous animals (all birds, some reptiles and some mammals) lay eggs. Viviparous animals 'give birth' to pre-formed babies.
Oviparous animals lay eggs that develop and hatch outside of the mother's body, while viviparous animals give birth to live offspring that have developed inside the mother's body. Oviparous animals include birds and most reptiles, while viviparous animals include mammals and some reptiles.
Oviparous means that the animal lays eggs that develop and hatch outside the mother's body. In reptiles, turtles are an example of oviparous animal.Ovoviviparous means that an animal lays egg but the egg stays in mother's body. The embryo receives nutrients from yolk sac instead of the mother itself. In reptiles, Grass snake is ovoviviparousViviparous means animals retain the egg inside the mother uterus, but the embryo receives nutrients from the placenta. It's mostly restricted to mammals.But many skinks and possibly also other lizards do have placenta like structures capable of transferring nutrients.Brian K. Speake, Jacquie F. Herbert and Michael B. ThompsonEvidence for placental transfer of lipids during gestation in the viviparous lizard, Pseudemoia entrecasteauxii
Animals that give birth, such as mammals, have internal fertilization where the embryo develops inside the mother's body before being born live. Animals that lay eggs, such as birds and reptiles, have external fertilization where the embryo develops inside an egg outside the mother's body. The main difference is in the way the embryo develops and is nourished during gestation.
what's the most significant difference between the holdovers" and animals in all other classes. what's the answer.
there is no difference. they are the same thing. Scatseems most often used to describe evidence of wild animals, and dung is more commonly used when speaking of domestic animals.

Chicken is oviparous as it lays egg which later on develops in an embryo. In viviparous condition the new organism is directly delivered from the mother an in case of mammals.
Answer:Reptiles are divided between Oviparous (egg laying) and Viviparous (live bearing). Viviparous reptiles give birth to live young. The majority of reptiles are oviparous but some snakes and lizards are viviparous.
They are both in english. They are similar to each other.
Oviparous parasites lay eggs outside of the host's body, while viviparous parasites give birth to live young inside the host. Oviparous parasites often release eggs into the environment where they can infect new hosts, while viviparous parasites transfer live offspring directly to the host during reproduction.
Viviparity is the development of young within the body of the mother, where the mother's body supplies all of the nourishment necessary for the development of the foetus. Human beings are a viviparous species. Oviparity is the development of young within an egg which is deposited outside the body of the mother and hatches outside. The nourishment which the infant needs is wholly contained in the egg. Ovoviviparity is a system midway between the two, where an egg is created with nourishment enough for the infant to grow, but it is not laid, but hatches within the body of the mother. To external appearance, an ovoviviparous species appears to be a viviparous one.

a mammal has fur and has milk and produces milk in its body but reptiles have scaly skin and live on water +++ Also: Mammals are warm-blooded and viviparous. Reptiles are cold-blooded and oviparous - and only a few of the reptile species live on (or in) water!
Animals that give birth, such as mammals, have internal fertilization where the embryo develops inside the mother's body before being born live.

Teleost fish The endoskeleton made of bone. Gills covered by operculam. Homocercal tail. Oviparous. ELASMOBRANCH endoskeieton made of cartilage. Gill slits present,not covered. Viviparous. Heterocercal tail.
The ONLY difference is that Protozoans are unicellular and animals multicellular
