Every summer shark sightings are reported - mainly because so many of us are at the beach or out on the water. This year however there seem to be fewer sharks around than usual and that's worrying for shark expert Riley Elliott. Riley, aka Shark Man, has a phD in marine biology, and is a producer and presenter for the Discovery Channel's Shark Week. He joins Susana from the Coromandel Peninsula to chat about what he has seen out on the water and why healthy shark numbers matter.
