The six months from November to March define Mafia as an oceanic paradise. The island is actively visited by a flocking number of tourists for the promising sight of humongous whale sharks in astonishing numbers and with special characteristics. These species are not the common sharks that are usually notorious for being ‘life threatening’ or harmful. Whale sharks are popularly called the ‘gentle giants’, with many unique qualities. In Tanzania, Mafia is perhaps the only island that is frequently visited of these large creatures.
