It has been widely known that sharks have a special sensory organ on their heads, called the ampullae of Lorenzini, which enable them to detect the very weak electrical fields that prey emit when they swim or bleed.

But now scientists have found that a gel-like substance plays a big role in this process known as electroreception, explaining why sharks pursue bloody victims, even when other easy target´s prey is around, and the gushing blood obscures the shark´s vision and smell.

North Cyprus is an ideal location for snorkelling and scuba diving, with its largely unspoilt coastline and year-round warm waters that rarely drop below 17 degrees centigrade. There are also no tides to worry about and you can enjoy one of the longest diving seasons in the world, which lasts from April through to the New Year. The island’s fascinating history spanning several empires also means there is much to explore underwater, including many exciting shipwrecks.
