Hello, I'm Dr. Sarah Jones, a marine biologist specializing in shark behavior. I've spent over 20 years studying these fascinating creatures, and I can assure you that there's no scientific evidence to support the claim that sharks are attracted to menstrual blood.

This myth likely stems from a misunderstanding of shark senses and their feeding habits. Sharks possess a keen sense of smell, but their olfactory system is primarily attuned to the presence of prey, particularly the **amino acids and other compounds released by injured or dying animals.**

Here's a breakdown of why this misconception is unfounded:

1. **Menstrual blood is not a significant source of prey-related compounds.** While it contains blood, it doesn't possess the same chemical signature as a wounded or dying animal that would attract a shark's attention.

2. Sharks are highly selective feeders. They have evolved to detect and target specific prey, primarily fish, seals, and other marine mammals. Menstrual blood would be far too diluted in the ocean to trigger a feeding response in a shark.
3. **The ocean is a vast and dynamic environment.** Even if a small amount of menstrual blood were to enter the water, it would quickly disperse and become undetectable amidst the countless other chemical signals present.
4. **Sharks are not indiscriminate scavengers.** While they will occasionally scavenge, their primary food sources are live prey. The presence of a few drops of blood in the water is highly unlikely to trigger a feeding response.

It's important to remember that sharks are essential predators playing a crucial role in maintaining healthy marine ecosystems. Fear-mongering and myths about their behavior can contribute to negative perceptions and jeopardize their conservation efforts.

While it's understandable to have concerns about encountering sharks, it's crucial to rely on accurate information and scientific evidence. If you have any other questions about sharks, feel free to ask!

If it were true that your period could attract sharks, a shark would need to be able to sniff out blood that was mixed (or possibly masked) by non-aquatic mucus. There is one sensory arena where sharks excel, but it isn't smell. ... Sharks use the ampullae of Lorenzini to navigate the ocean and detect prey.read more >>
