Mako Shark

Steve meets a super-speedy shark. Reaching speeds of 50kph, the mako is the fastest shark in the sea. With fast-swimming prey like tuna and mackerel, mako sharks need to move quickly. But how do they reach such meteoric speeds? Steve first snorkels with these lightning-quick sharks off the coast of San Diego in California, before getting under their skin in his shark lab, to reveal their hidden speed secrets.
