Fish use which type of fertilization? External \( \square \square \)

Many fish species utilize external fertilization, a species-specific method where the female releases eggs into the water, and the male simultaneously releases sperm to fertilize them. This fascinating process usually occurs in aquatic environments, making the timing crucial as numerous fish may gather in one area to increase the chances of successful fertilization. In contrast, some fish, like sharks and certain species of rays, adopt internal fertilization where the male transfers sperm directly into the female's body. This unique approach demonstrates the diversity in reproductive strategies within the fish kingdom, showcasing both adaptability and survival instinct in their quest for successful offspring.
