Tracking sharks

This month we submerge ourselves in the science of tracking sharks.
How do we follow them, where do they go, and what do they get up to
when we're not watching? We catch up with Ecocean's Brad Norman to
find out how he was inspired by the stars to help track the biggest
fish in the seas. Mahmood Shivji from the Guy Harvey Research
Institute tells us about how cutting edge genetic tools are helping
to track the trade in sharks fins. And Boris Worm chooses our
Critter of the Month. For information regarding your data privacy,
