External: Requires water for the sperm cell to unite with the egg cell because both the egg and the sperm cell have to be released into the water so the sperm may "swim" to reproduce.

Internal: Water is not needed. The sperm and egg cell is united through sexual reproduction inside of the body of a parent.
