Viruses reproduce within the living cells of the host and use the cellular machinery to synthesize their own genome and other components. To gain entry into cells, they have developed a variety of mechanisms to introduce their genes and proteins into host cells.
It is true they do have internal fertilization. This is also one of the reason why it is easy to differentiate between a male or a female shark on birth due ot internal fertilization. <span />
