Apparently a delicacy for whale sharks, the high-protein power diet out of the warm water day and night with her up to 6,000 litres of water per foot full hour suck and from strain thousands of about 10 cm long beard-like flakes – from their five lateral Gill slits on the so-called gill nets. Like all other sharks whale sharks have teeth, about 3000, which is however unclear benefit and function. The gentle giants belong to the 3 stirred among the sharks (the other two are the basking shark and the basking mouth). But in contrast to the giant sharks, whale sharks are active filter feeders. You actively create a suction and filter the food, mostly plankton, but also small crabs, smaller and larger fish such as sardines, mackerel, and even small tuna, then back off. While they swim directly on the surface, sometimes even in a vertical position.
But the impression here be dull eating machines at work, greatly deceives. It is believed that their brain with the help of special receptor cells at the same time accepts numerous environmental: mechanical, electrical, chemical and Visual stimuli. Nobody know until today, on how get the whale sharks for their annual meeting, works like the internal clock that allows them to arrive at the same time in the same place, nor where exactly they are the remainder of the year. It is also unclear whether at the regional meeting in fact animals of the same species gather, or whether there are separate populations. Also in the dark, information available about their life expectancy, their development up to sexual maturity or their mating behavior.
Quite apart from the fact that no one knows how many of these giants there at all. All people umwitterten their secret meeting the sea travellers will be doomed. Because they do not fear the people as an enemy, behave opposite even completely peaceful divers and touch, they are easy prey for fishermen who have seen it on their precious fins and their hot whitish flesh.
