Scientists have calculated the water temperature at which tiger sharks are most active and abundant.
They say the sharks, which are second only to great whites in attacking people, prefer a balmy 22C.
Shark populations may shift range as the oceans heat up, bringing them into greater conflict with humans, according to the scientific study.
For instance, tiger sharks may move into waters off Sydney in both winter and summer months. MORE
