1. SHARKS ARE BLOODTHIRSTY, MAN EATING MONSTERS While shark attacks do occur, most if not all of these attacks are accidental. Humans are not on the menu for sharks, and they do not try to hunt them. Instead, when shark attacks occur, it is likely because they have mistaken a human for a prey item. 2. SHARKS CAN SMELL A DROP OF BLOOD FROM UP TO A MILE AWAY Sharks can smell blood, but not from a mile away, and certainly not a single drop. Some sharks have a stronger sense of smell than others, and can smell blood maybe from a few hundred yards away, however it is not plausible that they would be able to smell such a small amount of blood. 3. SHARK FINS BACK GROW While some lizards can grow their tails back after losing them, this is not the same case for sharks. Sharks are hunted, oftentimes only for their fins, and then thrown back into the ocean. This is a death sentence, because their fins will never grow back. Instead, sharks without their fins will die a slow, painful death without being able to swim.
4. SHARKS HAVE NO PREDATORS Many people think sharks have no predators and are always at the top of the food chain. This is not true. Some species are eaten by their own kind and may be eaten by bigger sharks than them. Even the ultimate predator, the Great White shark has predators.
Killer Whales are known to go after and take down Great Whites in South Africa. However, the biggest and fiercest predators of sharks are humans, with approximately 100 million sharks killed by humans each year. 5 SHARKS ARE ONLY FOUND IN WARM, TROPICAL WATERS While there are certainly more species of sharks in waters closer to the equator and off the coast of tropical regions, sharks are widely distributed throughout the earth’s oceans. Sharks can be found in all five oceans and in most seas. Sharks like the Great White, Basking shark, Greenland shark, and Sleeper shark live in cooler, temperatures and sometimes polar waters. 6. SHARKS ARE ONLY FOUND IN SALTWATER This is mostly true, however there are species of sharks that can be found in freshwater or brackish water. Both bull sharks and species of river sharks are known to inhabit rivers. River sharks can be found in Southeast Asia and Australia, and Bull sharks can be found in the coastal waters and in rivers in North and South America, Africa, Asia and Australia.
7 ALL SHARKS NEED TO CONSTANTLY STAY MOVING TO SURVIVE It’s true that some species of sharks need to remain in motion to pass water over their gills to get oxygen into their bloodstream. There are certain sharks including like nurse sharks, angel sharks, and leopard sharks have additional specialized water passageways called spiracles that help to ventilate the gills. Spiracles allow these species of sharks to sit still or in one place for extended periods of time while still passing water over their gills.

While most species of sharks do actively track down and hunt their food, there are some species of sharks that have a less involved foraging strategy. Sharks such as the Whale shark and Basking shark are solely filter feeders. They feed on plankton, small crustaceans, and other invertebrates.
