Reproducing and Life Cycle


The ways cartilaginous fish reproduce varies. Some of them lay eggs, others of them are born alive. Some give birth to 60 offspring. Mostly it is fewer. The male has two organs called claspers, which release sperm into the female, where the egg is fertilized. Once the fish are born their parents don't take care of them. Some even appear to eat their babies.
