Can science stop sharks attacking humans?

RATE THIS! +35
Posted in Science on 1st Apr, 2014 01:22 AM by AlexMuller

Sharks have patrolled the oceans for at least 400 million years and evolved into a huge range of species. There are deep sea lantern sharks that glow in the dark, wobbegong sharks that grow shaggy beards, and majestic whale sharks, the biggest fish in the sea. But when many people think of these animals, one thing comes to mind: shark attacks. 

 

As a beachgoer, diver or surfer your chances of encountering a shark, let alone being killed by one, are in fact incredibly slim; lightning strikes, bee stings and car accidents all pose far more of a threat than sharks.

 
In reality, people kill millions more sharks than sharks kill people. A quarter of all shark species, and their relatives the rays, are threatened with extinction, according to a recent report from the International Union for the Conservation of Nature (IUCN).
 
The main threat to sharks is overfishing and in greatest peril are the largest species. But a controversial cull of sharks was recently ordered in Western Australia following a spate of attacks. Scientists are now looking at other approaches to deal with the shark attack issue.
 
Prof Shaun Collin is leading a University of Western Australia (UWA) team of neurobiologists who are learning to think like sharks.

Sharks should be protected in some way. I am not sure how this could be achieved by trying to change their behaviour and not attack humans - must be some simple and straight forward way

The most important thing when discussing the environment and protection is that is important to find a balance and tread a very fine line of protecting both humans and sharks at the same time Reply

These researchers are finding some interesting ways to manipulate the sharks' senses to discourage them from approaching and attacking people. One I find interesting is a "shark-proof" wetsuit designed to make people look like poisonous, black and white banded sea snakes, something that many sharks tend to avoid. I hope this works!

Another approach that could work is the idea of "bubble curtains" that could be deployed to keep sharks away from popular beaches. The curtains are made from perforated hosepipes across the seabed that pump air through and create bubbles that sharks may decide not to swim through. I prefer this to "shark-proof" wetsuit Reply

This initiative will not only be useful for swimmers, but also for the potential information it will provide to the scientific community about sharks. It was great effort to tag 320 sharks and the battery life of tags is up to 10 years so the scientific data that may be collected from this shark could be the biggest ever! Reply

This will benefit beach goers and their safety but importantly would help to protect great white sharks or other endangered shark species. This solution of warning is much better than a plan that permits fishermen to kill a big shark if it is swimming in a designated surfing or swimming area. Reply
