As humans proliferate, the demand on natural resources will inevitably cause predators to prey on unwary people as they have always had occasion to do in the past, whether pelagic shark or crocodile.

From a purely sociobiological perspective, given the known man-eating propensities of Nile crocodiles, coupled with its ecological niche of generalist feeding apex predator, is it fair to say it would be unpersuasive for any crocodile or estuarine ecology "expert" to theorize that the attacking crocodile in the recent fatality in Africa did so (1) on account of "mistaken identity" with a wildebeest; (2) because the victim was wearing shiny jewelry resembling a fish flashing in the water; (3) the crocodile's sensory faculties must be damaged so the crocodile couldn't differentiate prey; (4) locals were dumping dead sheep in the river in the general vicinity; or (5) crocodile tours habitually feed the crocodiles, thereby reinforcing the association of humans and food?

None of these theories are probative on the cause of death, or "motive" of an apex predator known to eat human beings. The crocodile opportunistically realizes a feeding event as the moment allows and metabolic will directs.

By analogy, the Red Sea attacks coincide with the known man-eating propensities of the Oceanic Whitetip. None of the aforementioned theories are applicable, or necessary. The only discernable, selective pressure on the species is a material depletion of the Oceanic Whitetip shark's available fish stocks due to commercial fishing.

Rabid bears, like alleged sharks swimming around with "sensory damage" that affects such basic survival strategies, are not nearly as dangerous as ravenous ones- especially those that will deny an instinctual restraint of human predation in such immediate proximity to society in order to survive, e.g., juveniles that may fail on the verge of "success"; often they are displaced from "normal" feeding opportunities by more dominant sharks when resources are scarce, but nonetheless able. "Too able" - Brave New World

I think this is a "rogue" shark. Another shark simply realized an immediate opportunity. But like the crocodile, as the Africans say, perhaps the "rogue" shark is "smiling."

A Mako shark? Hmm. That would be TWO pelagic sharks coming in very close and attacking in the same manner.

Considering some people "in the know" are also indicting much more "ludicrous" sources, based on the facts here, until different evidence is available, I think all are Oceanic Whitetip attacks. I think they have an instinctual behavioral adaptation to capitalize on opportunities as they last, e.g., "Opportunity makes a thief." - Francis Bacon


Here, once the attacks "started", there was likely still blood in the water for a considerable time. The Oceanic Whitetip sharks are like a gang. Not in terms of self-defense, unfortunately. Once the blood of the 1st human victim had been "released" by the "rogue" shark, the other sharks in the area got electric and they are, remember, still hungry. This should arguably be deemed "one single" predation event. That explains why the attacks didn't "migrate" elsewhere.

Solution?

Besides assume the risk when you enjoy the ocean, I think the government should tow a dead carcass far enough away to lure the sharks at the beach away.

Wait.

(enter JAWS)

Maybe not.

The sharks on the photos are not Oceanic White Tips, there Mako Sharks.

I don't agree with killing sharks after attacks, but "Maybe we should kill those tourists..." is an idiotic comment.

"...by what had been presumed to be a single oceanic whitetip."
..confirmed that two whitetips have been caught and killed"

Just to be on the safe side the decided to kill "all" the whitetips they found ??

Colin

I wasn't aware we still killed sharks after attacks. I thought we just accepted nature as it is. Maybe we should kill those tourists for not respecting the domain.
