Animals that undergo external fertilization include many fish, amphibians, and aquatic invertebrates. Species like salmon, frogs, and sea urchins release eggs and sperm into the water, where fertilization occurs outside the body. This method often requires moist environments to prevent gametes from drying out and to increase fertilization success.

Differentiate between internal and external fertilization?
Internal fertilization occurs inside the female's body, where sperm fertilizes the egg, while external fertilization occurs outside the body, usually in water, where eggs are fertilized by sperm.

Additionally, internal fertilization provides better protection for the developing embryos compared to external fertilization.
