Revealing the mystery of the world's largest fish

Despite its enormous size, whale sharks are completely harmless to humans.

High-tech electronic cards mounted on whale sharks - the world's largest fish - have revealed their journeys and feeding grounds.

Researchers in Belize (an independent Commonwealth country, in Central America, the Caribbean Sea) tracked these sharks as they dived almost 1 kilometer to feed, and Find traces of fish that are laying to eat eggs.

"Our research shows that this shark dives much deeper than previously predicted, to depths of more than 1,000 meters to find food," Rachel Graham, of the US-based Wildlife Conservation Association. said."At this depth, the temperature of the water is only a few degrees above the freezing point, and it explains why the tropical whale has an independent fat layer just below the skin - which confuses scientists. for many years ".

At night, whale sharks often wander in shallow waters, eat ephemeral and store deep dives to retain heat for the day.These deep dives often end with rushing to the surface at high speed, perhaps to catch the flow of oxygen into the body after a period of time in deep oxygen deficient water.

Around the time of the full moon, Cubera snapper usually gathers near the coast to lay eggs, forming large tufts of bodies writhing in a "soup area" made of fish eggs.With whale sharks, this was a banquet, and they swam around, going through the soup over and over again, filling their huge mouth with goldfish bun.

Whale sharks are up to 20 meters long, and are listed as endangered sensitive species.Researchers believe that a recent discovery of their feeding ways and locations will help humans map out the tourist activities around whale sharks without harming them.Belize is the second largest coral reef system in the world and a natural heritage site recognized by UNESCO.
