Back in February, I wrote an article about a trial run for a shark exclusion net in Cape Town, South Africa. The idea behind a shark net is to make beachgoers feel safer in the water, but they can have pretty negative effects on the local ecosystem.

Scientists from Stellenbosch University recently developed a more eco-friendly shark barrier, called Sharksafe, that can be used as an alternative to a shark exclusion net. Current shark nets may be effective at keeping sharks away from popular swimming beaches, but they are responsible for the deaths of many other animals including dolphins and turtles.

Sharksafe is a new kind of barrier made up of vertical pipes that resemble kelp floating in teh water. It uses magnets that effectively deter many shark species..

In the following video, you can see Sharksafe in the water and learn more about it from the researchers involved.
