Although different shark species have different mating habits, all sharks reproduce sexually when the male shark's clasper inserts into the female shark's cloacal opening. The embryos gestate for between 9 months and 2 years, depending on the particular species. Some species of shark only give birth to one pup at a time; others can produce up to 100 pups.Different species of shark reach sexual maturity at different times. The great white shark becomes sexually mature at around 15 years of age and has a lifespan of about 30 years, although some have been known to live for a century. The hammerhead shark also lives for around 30 years. At sexual maturity a shark's rate of growth slows down dramatically; however she will continue to grow until the end of her life. All sharks will reproduce as often as they can according to their gestation period.
