The scars many whales bear throughout their lives resulting from shark attacks are more than sufficient evidence sharks will have a go if an opportunity arises.
A pair of killer whales are hunting and preying on South Africa's great white sharks, forcing the sharks to flee.

Researchers have discovered that great white sharks are more social than previously thought. Using specialized tags, they tracked six sharks and found that some stay close to each other when hunting.
The death of 57-year-old Paul Millachip at Fremantle’s Port Beach is a reminder that shark bites, though rare, can be tragic. New research aims to reduce the risk by understanding sharks’ vision.

Sharks grow slowly and produce few young compared to bony fishes. In many cases, this means that their populations are fished out faster than can be replenished if not well managed.

Fatal shark bites are very rare. But the stats do suggest that the likelihood of an attack proving fatal is higher in Australia - probably because our waters are home to the “big three” dangerous species.
A shark’s nose is chemosensory only, and it doesn’t join up to the back of the throat like ours does.

LIfeguards could potentially have a new ally in the fight to reduce shark incidents: drones that can spot when a shark swims nearby, and automatically alert authorities.

Shark nets are controversial, which is why the New South Wales government is investigating a host of other ways to keep humans and sharks apart – some more tried and tested than others.

The best way to guard against shark attacks is to study them, not kill them. Because while the alleged “shark boom” almost certainly not real, the more we know about sharks, the better.
