Compare and contrast the reproduction of perch and shark
Sharks don't reproduce like other fish. Males have two organs called claspers attached to their anal fins. When mating they will insert one of them into the females cloaca to transfer the sperm that will fertilize the eggs.
When a female white perch is ready to mate, a group of males surrounds her. She releases her eggs into the water and they stick to the bottom. All the males release their sperm at the same time, so the eggs can be fertilized by different fathers. White perch breed once a year between March and July.
