While filming Blue Water, White Death in 1969, 200 km off the South African coast, we left the safety of our cages, which we tied to a dead whale, and fought off hundreds of large sharks, eventually making a place for ourselves in the midst of the pack. We taught those sharks, all of them extremely dangerous, respect in a few frantic minutes. The f...
Sharks’ curiosity attracts them to any unusual creature in their environment. A small animal like a dog is more likely to be considered prey than a big animal.
It has been said that human blood will attract a shark from kilometres away. This hasn’t been our experience, but perhaps we’ve never bled enough to be attractive. We know that a harpooned whale bleeding its life into the open ocean as it cries in agony can attract hundreds of large, very dangerous sharks. Much to the horror of sailors in the water...
Sharks are easily taught a simple action. I once trained a whitetip reef shark to swim towards me over a piece of pink coral. When she did it correctly I rewarded her with a piece of fish. When she swam towards me any other way I hit her on the head. Within 45 minutes I had that shark performing exactly as I wanted. Several hours later I returned t...

Bull sharks will swim up rivers into brackish or even fresh water, especially females when they are ready to pup. Although most sharks have sharp eyesight, rivers can be murky. In low visibility conditions, sharks investigate anything unusual with their teeth. A gentle nibble of a shark’s razor-sharp teeth can be fatal, however, for a thin-skinned ...
This was once widely thought to be true, but it isn’t. Most sharks can rest on the bottom and pump water over their gills. The lovely and endangered Australian grey nurse shark can hang almost stationary in the water. They’re often seen resting in groups, waiting to go out and forage under the cover of darkness.
With sharks, as with most animals, if you are larger and better-armed than your companions you’ll generally have right of way. At Shark Reef off Pacific Harbour in Fiji, we’ve witnessed a big tiger shark scatter a group of feeding bull sharks despite the latter being very large themselves. On one occasion, however, the bulls joined forces and out-m...
