The pups measure 97–120 cm (3.18–3.94 ft) long at birth, relatively larger than the young of the shortfin mako, and have proportionally longer heads and pectoral fins than the adults.[2][12] Capture records off Florida suggest that during the winter, females swim into shallow coastal waters to give birth.[13] Male and female sharks reach sexual maturity at lengths around 2 m (6.6 ft) and 2.5 m (8.2 ft), respectively.[10]
