World-first Discovery: Astonishing Whale Shark Dive and Ascent Behavior

These beautiful creatures just get more and more amazing with time and understanding!

The secret double life of Ningaloo’s whale sharks has been discovered by Murdoch University scientist Brad Norman and his Swansea University (UK) colleague Professor Rory Wilson.

In a world-first scientific discovery, the two Laureates of the international Rolex Awards for Enterprise have revealed that whale sharks undertake astonishing dive and ascent behaviour to conserve energy. This type of behaviour has not been quantitatively recorded in sharks or fish before.

Murdoch scientist Brad Norman says the dynamic bounding underwater 'flight' of the world’s biggest fish contrasts with its reputation as a slow, surface cruiser.
