Global One (G1)— Climate change is certain to affect many aspects of life — rising tides, higher temperatures.
It also may cause sharks to become smarter and sharper predators — that’s according to a study published by biologists at Austrailia’s Macquarie University.
Scientists have found sharks raised in warmer than average waters will choose to make right turns more frequently than other sharks.
It doesn’t sound like much, but it actually means a whole lot of other important theories about sharks and global warming.
See, the right turns are a sign of a shark’s “lateralization” — the part of the brain that controls an animal’s actions on one side of the brain or the other.
The sharks raised at the higher temperatures have stronger lateralization.
The study’s lead author says, “Lateralization may enable sharks to process information more efficiently, even if their brains are smaller or less well-developed.”
The researchers say this could change the way they catch prey — making them deadlier hunters.
