The shark species that is most commonly associated with attacks on humans is the great white shark (Carcharodon carcharias). Great white sharks are known to be responsible for a significant number of unprovoked shark attacks on humans. They have a wide distribution and can be found in coastal waters around the world, often in areas where humans also frequent recreational activities such as swimming, surfing, and diving.
However, it’s important to note that the number of shark attacks on humans is relatively low compared to the vast number of interactions that occur between sharks and humans in the ocean. Sharks typically do not seek out humans as prey, and most shark encounters result in no harm to humans.
