The invitation to film sailfish off the coast of Mexico was one that we had to take. They are the fastest fish in the world, and getting up-close and personal while they hunt down the bait balls of sardines travelling from further north was spectacular. It isn’t easy work. They bait balls are very different to those found in South Africa.
They are smaller and faster moving. Only when predators have reduced their number considerably do they seem to lose the will to flee – almost accepting their fate. animal behaviour was fascinating. At one stage a large animal changed colour dramatically, and its body became vividly striped. As it did so, all the other fish disappeared into the gloom, leaving it alone to attack the sardines. Once it had been successful the others returned.
