At over 12 feet in length and weighing up to 200 pounds,the ray is armed with a barbed tail putrid with toxins and bacteria and capable of piercing any armour with razor-sharp accuracy. But for all their fearsome weaponry, rays are surprisingly gentle creatures that can be hand fed, even in the wild. This film offers a detailed insight into the life of this enigma of the sea.
