Some land mammals use internal fertilisation because it is safer, and they can make sure that their offspring/eggs are not in danger. They can also make sure that their offspring/eggs are not being eaten by other animals.

Why must external fertilization in animals always occur in water?
Not all species that are aquatic use external fertalization. Dolphins se internal fertilization but it is very dificult because they would have to evolve adapted sexual organs and i dont think fishes have the right organs for internal fertalizations so they juust eject it into water. I'm not sure this is correct but i hope it helps. You might nneed to check it before you use it in any peices of writing.
