What classes of vertebrates use external fertilization?
Two classes:Fish and Reptileswhat is interior and exterior fertilization?Internal fertilization is when the sperm is directly deposited into the female, who produces eggs and fertilizes them in her body. External fertilization is when the sperm and eggs are released outside of the body and meet outside of the body, not like how chithra described. Birds do not have external fertilization, the fertilization still occurs in the body, they just do not produce live young.Examples of external fertilization are in plants like moss or algae, where the sperm and eggs meet outside of the parent's body and produce a zygote, which then grows into a mature plant. External fertilization in animals are usually in marine organisms, like sponges, because the sperm needs to swim in water to meet the egg.-Your Welcome

What are the similarities of internal external fertilization?
Internal fertilization takes place inside the body of the female. It is necessary for animals which live on land (terrestrial animals) and is retained by aquatic animals descended form terrestrial ancestors eg whales and dolphins. External fertilization takes place outside the body of the female. It usually takes place in water, usually the environment in which the animal lives eg fish and amphibians. This is because eggs and sperm would dry out and die if they are not kept wet. Internal fertilization is more certain than external fertilization so fewer eggs need to be produced. After internal fertilization eggs can be protected and fed while developing inside the mother's body. After external fertilization the eggs are potentially exposed to predators and so must either be produced in very large numbers or protected by the parents or both.
Predict whether an animal that reproduces by external fertilization is more likely to live in water or on land?
The answer is this website SUCKS!
