How do beaches protect from sharks?
Shark barriers are often made out of netting; held in place by a system of piles, anchors and buoys. Netted barriers are susceptible to damage from strong ocean forces and so are generally limited to sheltered bays and beaches and favourable seasons and weather conditions.
Why do divers touch sharks noses?
