Why Do Whale Sharks Get So Big?

  • -

Whale sharks are the world’s largest fish, growing to a length of 18 m long, about the same size as an articulated bus on a city street.

It’s a paradox that these immense animals feed on very tiny prey -shrimp-like animals called krill that occur in enormous numbers in the world’s tropical oceans. Whale sharks dine on krill by filtering water through specialised plates on the gills, an energy intensive process which has the potential to cool the animal very quickly when their food is found in deep, cold water.

How do whale sharks cope with this problem, while finding enough food to eat?

Perth-based AIMS fish biologist Dr Mark Meekan will take you into the exciting world of whale shark research in this webinar to discover how new tagging techniques including animal-borne cameras are revealing the behaviours of whale sharks at Ningaloo Reef in Western Australia and giving insights into the behaviour, ecology and evolution of these ocean giants.

Note for WA audiences: this event starts at 9.00am AWST.
