Ignorance is not exclusive it seems, comments dont end with question marks.
It has long been my understanding that sharks are attracted by scent and vibrations.. blood being one of the scents and the vibrations that are created by the flexing of knees and ankles which apparently can mimic a fish in distress.
But hey.. Everyones gotta start somewhere, banging ones head on a wall only satisfies the self and resolves nothing.. Inspire us with your wisdom kind sir..

The consensus among marine biologists and scuba divers is that menstruation does not increase the risk of a shark attack.

Thank you for a reasoned response.. being someone with zero interest in fish as a food source one works on info gleaned from Jacque Cousto etc..
Oh.. And Jaws..

I would be very surprised if that was true, divers and diving support companies have an agenda, it's to keep people diving! Let's face it, ANY kind of bloody offal seems to attract sharks, that's universally how people in the know attract them. But is the percentage difference in attacks huge? I doubt it.
But I would be on careful watch if my daughter was diving on her period!

Since diving isn't absolutely necessary, I would advise my wife/daughter against it as well.

However
From the International Shark Attack Files at the Florida Museum of Natural History:
“... Menstrual blood almost certainly can be detected by a shark, and we’re sure urine can be as well. Do we have positive evidence that it is a factor in shark attack? No, and until some menstruating and non-menstruating divers volunteer to take part in a controlled test we’ll never prove it. In our opinion it likely is attractive to sharks in certain situations...
... Our advice? Don’t worry about it. Lots of women safely dive while menstruating. Although we haven’t got solid scientific data on the subject, so far we haven’t seen any obvious pattern of increased attacks on menstruating women.

Dr. Tricia Meredith is truly an expert in shark smelling – if you want to know more about her expertise check out.

As to your assertion “Let's face it, ANY kind of bloody offal seems to attract sharks”
A shark might be able to smell you, but that doesn't mean it will equate that smell with food. Or, as Dr. Kajiura put it, "You can smell a landfill, but it won't make you want to eat it."

Curious how you state "The consensus....". Do not see it supported by your 2 links which are void of empirical evidence.

Per my previous post #41
From the International Shark Attack Files at the Florida Museum of Natural History:
“... Menstrual blood almost certainly can be detected by a shark, and we’re sure urine can be as well. Do we have positive evidence that it is a factor in shark attack?

The International Shark Attack File (ISAF) is a compilation of all known shark attacks, that is administered by the Florida Museum of Natural History, and the American Elasmobranch Society, a professional organization comprised of international workers studying sharks, skates and rays.
Of the over 500 different species of sharks found in the world’s oceans, only about 30 have been reported to ever attack a human.
Of these, only about a dozen should be considered particularly dangerous when encountered. The shark species responsible for most unprovoked attacks on humans are the white (Carcharodon carcharias), tiger (Galeocerdo cuvier), and bull (Carcharhinus leucas). All sharks, large and small, are however predators and could be capable of inflicting wounds if provoked. They should all be treated with respect when encountered.
Worldwide there is an average of 80 shark attacks every year.
2018 Report ➥ https://www.floridamuseum.ufl.edu/sh...dwide-summary/

Although the relative risk of a shark attack is very small, risks should always be minimized whenever possible in any activity. The chances of having an interaction with a shark can be reduced if one heeds the following advice:
Always stay in groups since sharks are more likely to attack a solitary individual.
Do not wander too far from shore — this isolates an individual and additionally places one far away from assistance.
Avoid being in the water during darkness or twilight hours when sharks are most active and have a competitive sensory advantage.
Do not enter the water if bleeding from an open wound or if menstruating — a shark’s olfactory ability is acute.
Wearing shiny jewelry is discouraged because the reflected light resembles the sheen of fish scales.
Avoid waters with known effluents or sewage and those being used by sport or commercial fisherman, especially if there are signs of bait fishes or feeding activity. Diving seabirds are good indicators of such action.
Sightings of porpoises do not indicate the absence of sharks — both often eat the same food items.
Use extra caution when waters are murky and avoid uneven tanning and bright colored clothing — sharks see contrast particularly well.
Refrain from excess splashing and do not allow pets in the water because of their erratic movements.
Exercise caution when occupying the area between sandbars or near steep dropoffs — these are favorite hangouts for sharks.
Do not enter the water if sharks are known to be present and evacuate the water if sharks are seen while there. And, of course, do not harass a shark if you see one!

Good grief!

This is what happened to a "shark expert" wading with bull sharks .......

Every "shark expert" in the Bahamas, and Florida, who are hand feeding sharks, 100 per cent sure they know what a prehistoric instinct driven animal will ever do, should watch that video.

Getting luck, mixed up with knowing what they are doing, is a common problem with shark handling thrill seekers.

In the Abacos, in the very first day on my 3 months cruising, I was not aware of the danger to through fish remains in the bay. It tooks only 2 minutes for a Bull shark to be under the cat for them. They have an infinite good odor detection and I would think that a menstruated woman with "some leaks" would be detectable as much as fish remains. They are programmed for that.


About those saying there is no effect... do they made tests with menstruated women in a cage, repeated 20 times in different sites and on the other side, the same with mid-period women ? Please be scientific !!!

I see you are unwilling or unable to rise to challenge of finding credible support for your opinion.
