Sawshark
Saw sharks have a relatively slow life history. Mating season occurs seasonally in coastal areas. Saw sharks are ovoviviparous meaning eggs hatch inside of the mother. They have litters of 3–22 pups every 2 years. After 12 months of pregnancy, the pups are born at 30 cm long. While in the mother, pups' teeth are inverted into their mouth to prevent harm. The sharks care for their young until they are sexually mature at 2 years of age and at which point can fend for themselves. Saw sharks typically live more than 15 years in the wild They can be found living in solitary or in schools.
