How are reproduction in fish and humans different?

Reproduction in fish typically involves external fertilization, where eggs and sperm are released into the water, allowing fertilization to occur outside the female's body. In contrast, humans reproduce through internal fertilization, where sperm fertilizes an egg inside the female's reproductive tract. Additionally, fish often lay large quantities of eggs with minimal parental care, while humans typically have a single offspring (or a few) and provide extensive parental care during development. These differences highlight the diverse reproductive strategies adapted to their respective environments.
