Tiger sharks: Apex predators or lazy scavengers?

RESEARCHERS have discovered tiger sharks are "lazy" when it comes to their food sources.

They prefer to scavenge on dead or weakened green turtles rather than hunt healthy individuals despite more opportunities to do so.

Adam Barnett from James Cook University said green turtles did not perceive tiger sharks as a major threat during their nesting season.

"In years when nesting numbers are high, at the extreme, up to as many as 80 individuals a night may die, and some of these remains eventually get washed into the water during high tide," he said.
