Jun 23, 2011 In 2009 scientists discovered the largest whale
shark population so far in the waters of Mexico’s Yucatan
Peninsula. According to the air and water surface observations,
at least 420 whale sharks were gathering together to enjoy the
eggs that tuna just spawned. These photos were taken from a
small airplane, which showed a ship surrounded by sharks. It
revealed a new spawning ground of tuna and also made scientists
to understand a new phenomenon of the behavior of whale shark. A
whale shark was feeding. The whale sharks gather together in
east coast of Mexico every summer, such activities are
predictable, for the rest of the time, however, it is still a
mystery that where they are.
