OK instinctual reaction to what appears to them be other sharks ‘dying’ around them because of the smell. Animals do have fight or flight instincts, which react to certain situations. Whether thought is j volved or not I don’t know, they do seem capable of making decisions about what to do, but also go into complete purely instinctual reaction at times like during feeding frenzies
Don’t get me wrong, I know virtually nothing about sharks. I merely suppose that when they’re looking for food, they will put just about anything in their mouths. Shark flesh can’t taste that different from non-shark, and anyway, many animals eat their own kind.
What if the shark misinterprets “eau de cadavre” and proclaims “You killed my father! Prepare to die!”
If I had to buy a shark repellent, I think I’d go for a pod of killer whales.
