Which animal has internal fertilisation and internal development?

Answer 1

It's "fertilization" btw...

To many to list... A good way to think of these, with of course, a few rare exceptions, is any animal that gives birth to a live baby or an egg that is hard or leather-like as soon as it's laid by the female, creating an instant protective barrier for the developing baby inside. (Different from externally fertilized eggs, which are often jelly-like, clear or translucent, and have an soft, pliable, easily permeated exterior so that the male can fertilize them simply by producing sperm on or near it and allowing gravity and the currents to spread it over the eggs permeable exterior.)

- Mammals - horse, cows, pigs, humans, kangaroos, koala bears, elephants, dogs, cats, lions, tigers, bears, platypus, etc.

- Reptiles- alligators, crocodiles, sea turtles, land turtles, tortoises, boa constrictors, pythons, etc. etc.

- Birds - chickens, ducks, eagles, hawks, crows, robins, cardinals, egrets, vultures, etc. etc.

N.B: No, fertilization is American spelling only, in Australia at least it is spelt fertilisation

Answer 3

one example of a animal that uses external fertilization is a fish, the female releases the eggs than the male fertilizes them.

an example of a animal that uses internal fertilization is mammals, by fertilizing the eggs with them remaining in the mother.

Answer 4

Mammals are animals that have internal fertilization and internal development. Monotremes are the exception; this small group of mammals displays internal fertilization and external development.
