RUNNER-UP, ANIMAL BEHAVIOUR
Crested horn shark, Heterodontus galeatus
A crested horn shark feeds on the egg case of the related Port Jackson shark. Each spring Port Jackson sharks gather on shallow reefs to breed and hide up to 10 eggs. Crested horn sharks make the most of the opportunity, searching the rocky crevices for an easy meal.
