Six bull sharks which had occupied a lake in a golf course near Brisbane for almost twenty years are the subject of a scientific study by a German researcher.
Hole number 14 at Carbrook Golf Course in Brisbane, Australia, is bordered by a 20-hectare lake on the shores of which, some time ago, you had to think twice before playing a stray ball. . Because, for almost twenty years, the water obstacle was populated by bull sharks, a species that can reach 3.50 m in length and is known to be of the aggressive type.
In 1996, violent floods in adjacent rivers swept six young individuals into this lake, who found themselves trapped there once the waters receded. We know that the bull shark adapts well to fresh water, especially the young which can grow there sheltered from the jaws of other sharks.
