Far out to sea in the deep waters of the Pacific, a growing swirl of fish glistens just below the surface, advertising themselves as a tempting catch for a school of yellowfin tuna. With the help of internal body temperature regulators, the tuna crank up an extra spurt of speed, powering through the waves as fast as a galloping horse into the centre of the feast.
But the feeding frenzy quickly ends as a lethal ‘fish aggregating device’ (a floating piece of debris placed to attract feeding fish) ensnares the tuna. Open ocean species like tuna are often drawn to coconuts, logs, seaweed or other objects bobbing around in the sea. When these are topped with identifying flags or GPS units, the hunter quickly becomes the hunted.
