Birds develop internally, within the egg, where they undergo rapid physical changes before hatching. The egg provides protection and nutrients for the developing embryo, allowing it to grow and develop until it is ready to hatch. Once hatched, the bird continues to grow and mature externally in its environment.
Fish develop externally, meaning that fertilization and embryonic development occur outside of the parent fish's body. The eggs are often released into the water where fertilization takes place, and the embryos develop independently until they hatch.
