Can Sharks Smell a Drop of Blood from Miles Afar?

The chances that one day you will encounter a shark are minuscule, small, shall we say, teeny tiny. And still, there are dozens of frightening myths surrounding these predators, even though most of them are misconceptions. For example, everybody knows that sharks have a very developed sense of smell that’s hundreds of times stronger than yours.
It's probably no wonder that sharks can detect tiny amounts of different substances in the water, right? But what about the belief that sharks can smell a drop of blood from miles away? Is it true? And how much time will you need to get back to the safety of the beach and get a band-aid if you, say, cut your foot on a sharp stone while swimming in the ocean?

SUMMARY:
- While some shark species can identify the smell of blood from a quarter of a mile away, it doesn't reach them right away.
- Even though some sharks can decipher smells better than others, no shark will be able to smell your blood in the water from farther than a thousand ft away.
- By the way, few people are aware that sharks aren't that interested in hunting humans. Most of them are very particular about their diet.
- There’s a stereotype that sharks purposefully hunt humans. But most shark attacks happen because these predators mistake swimmers for their usual prey.
- A few shark species won't be able to breathe if something prevents them from moving. But the rest of the predators use either both breathing methods or the buccal pumping method, and can easily rest on the seafloor.
- It’s been said, "If a shark is heading toward you, hide among jellyfish." Well, if you want to waste your time and hurt yourself, go ahead.
- It's another common misconception that all sharks are predators.
- Some sharks can even be found in lakes and rivers with fresh water!
- Among more than 400 species, there are both tiny ones, like the 8-inch-long deepwater dogfish, and impressive giants, such as the 40-ft-long whale shark.
- Despite their reputation as merciless and fearless monsters, you can stare a shark down or intimidate it.
- Sharks hang out mostly close to the surface. If you hear this statement, you should remember that it's nothing but a misconception.
- Sharks can attack and bite from any angle.
- The average shark's lifespan doesn't usually exceed 70 years.
- Sharks do NOT have a tongue, despite what some movies may show you. On the other hand, they have something that looks similar to the human tongue, but this organ is called the basihyal.
- Sharks do not and can not swim in reverse. Their tails propel them, and their pectoral fins help them to keep balance and turn.
