African Cichlid Fish
Female Cichlid fish produce orange colored eggs. Once laid, the female puts the eggs in her mouth. Some males have developed a pattern of orange spots on their anal fin. The male will display their anal fin which attracts the female for she thinks the orange spots are eggs she has missed. The male then takes advantage of her for when she comes to examine his spots, he will project out sperm and fertilize the eggs which are in her mouth.
