The whale shark is the largest fish, growing to 12m or more. But despite its size, it (like whales) feeds by filtering plankton, krill and small fish.
They are a unique and iconic species that stands out, never mistaken for another species. They are giants in a microscopic world; dominators where all else cowers; very visible where all else is disguised.
They are an icon of freedom. They are as comfortable skimming the warm surface waters in the sunlight as they are under the pressure of thousands of metres of water in the coldest, deepest, darkest depths. But they also follow a rigid schedule on to the next feeding rendez-vous. They are gourmets, travelling vast distances to be in particular spots at exactly the time a short-duration spawn of a particular type of food takes place. Moving on as soon as that food is depleted, it is hard work over many days to reach the next rich area. On the way there are few feeding opportunities.
