Shark Repellent: a new study indicates visual cues could be a deterrent

(Before It's News)

As a follow up to my post this past Sunday on the Australian government’s attempts to control white sharks off the Western Australian coast by a variety of often fatal means, new research has come out regarding another avenue for developing a shark repellent: Eyesight.

According to RedOrbit.com, researchers from Australia have been studying the brains of cartilaginous animals, which includes sharks and rays, and their conclusions point to some species of shark as having a more developed brain than previously thought.

There isn’t an implication that the sharks are “smarter” than previously thought, as that often implies intelligence of a sort that we associate with humans.  Rather, while some sharks have developed brains along an evolutionary path that is similar to vertebrates including humans, the sensory abilities of the sharks are perhaps broader in scope and therefore can have an impact on their behavior more than previously suspected.

While chemical shark repellents have focused on confusing or disrupting a shark’s sense of smell, the new research poses the idea that visual cues might serve as effective repellents.

And what visual image would a shark possibly find threatening or repelling?
