Few organisms in the ocean can match the fast life cycle of the dolphin fish, coryphaena hippurus. Dolphin reach sexual maturity at four to five months, where it takes a king mackerel three years to spawn. The world-record dolphin, 87 pounds was believed to be slightly less than five years old. By comparison, the world-record king mackerel, a 93-pound fish, was thought to be closer to 25 years old.
