Migrating over 800km, tiger sharks reach Raine Island on the Great Barrier Reef at exactly the same time every year. Their migration is timed to perfection in order to feast on the glut of 26,000 nesting green sea turtles that come here to lay their eggs. Unofficially known as the dustbins of the sea, tiger sharks do not have to waste time hunting live turtles. Instead, they are able to feast on those turtles that die in their attempts to reproduce.
