can toad have external fertilization
Because - external fertilisation is 'left to chance'. There's no guarantee that every egg laid will be fertilised by sperm. Internal fertilisation is much more successful.
Internal fertilization is like animals having sex....the egg is fertilized on the inside. External is when the egg is fertilized on the outside (like when frogs lay eggs and they need to be fertilized before they can hatch).
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. Internal fertilization is common in land-dwelling animals, while external fertilization is common in aquatic animals. Additionally, internal fertilization provides better protection for the developing embryos compared to external fertilization.
Mainly fishes are living in water and they are not having the proper fertilization system in side its structure, so they prefer external fertilization process.
Marine mammals have internalized genitalia for streamlining.
