What is different about frog reproduction to human?

Frogs are amphibians, so they require water, such as a pond or a puddle to reproduce. The female frog lays her eggs in the water, and the male frog releases his sperm in the water while the female is laying. So the frog sperm swim through the water to reach the eggs. The frog eggs then grow and develop outside of the female's body. If the water dries up, all of the eggs would die.

In humans, the fertilisation of the eggs occurs inside of the female, and the fertilised eggs develop inside of the female. This is an important difference, because the inside of female humans is always moist, so we don't have to depend on an external water source to reproduce.
