DESCRIPTION OF WHALE SHARK.

The Whale Shark has a particular characteristic that sets it apart from other sharks: Its beautiful skin with polka dots and light colored lines. Its skin measure up to 10 cm thick. The whale shark usually have a length of 31 foot and a weight of 9 tonnes, although sharks of more than 40 foot and 21.5 tonnes have been observed. Its wide mouth can open about 1.5 meters. Inside its mouth there are 300-350 rows of teeth and 10 pairs of useful pads to filter its food. These animals are not excellent swimmers because when swimming with the whole body, they hardly reach the speed of 3 mi/h. This shark has been observed alone or in groups formed by 100 or more specimens. The whale shaks can live with other groups of fish and stingrays.

WHALE SHARK FEED.

Only three species are fed by filtration, and the whale shark is one of them. When it opens its jaw to feed, a lot of water is also absorbed, so it is expelled through a filter located in the gills, storing the important food. If something gets caught in its gills, this fish uses a kind of “cough” to remove the obstruction. They feed on plankton, jellyfish, anchovies, fish larvae, corals, phytoplankton, algae, krill, crab larvae, squid, sardines, mackerel and tuna. The reason for the presence of teeth is unknown, since they are not used for eating.
