What are the Advantages of internal ferterlization over external ferterlization?

Internal fertilization offers several advantages over external fertilization. Firstly, it provides a more controlled environment for the fertilized eggs, reducing the likelihood of predation and environmental hazards. Additionally, internal fertilization often allows for greater parental investment and care, enhancing the survival rates of the offspring. Lastly, it can increase the likelihood of successful fertilization, as the gametes are brought together in a more direct and protected manner.
