Buildings within the brains of nice sharks are just like those present in people, and these may very well be the important thing to forestall additional shark assaults. Animal biologists on the College of Western Australia have found that the brains of Carcharodon carcharias have similarities when it comes to the areas which might be devoted to visible enter to these present in human brains.

The scientists revealed their findings within the journal Brain, Behavior and Evolution. Bigger optic tecta within the mind of sharks are just like the superior colliculus construction in human brains. These areas deal in conduct in relation to seen objects, and are related to an elevated reliance on imaginative and prescient in C. carcharias. Nice white sharks have giant components of their brains related to visible enter, that means that they may very well be way more receptive to repellents concentrating on visible markers, states Kara Yopak, a analysis affiliate and co-author.


Present shark repellent know-how depends on non-visual deterrents, similar to electrical pulses and chemical compounds. Understanding how C. carcharias‘ brains work, significantly how they make the most of visible stimuli, may result in extra environment friendly and extra focused repellent merchandise.

For instance, a shark could acknowledge a toxic sea snake’s markings, and swim away. This info may very well be used to repel sharks.
