Do sharks go into a frenzy at the smell of blood?
Sharks do have a very keen sense of smell and are attracted to the scent of blood, as it signals the presence of injured or wounded prey. However, the idea that sharks go into a "feeding frenzy" at the scent of blood is largely a misconception perpetuated by Hollywood movies. While sharks may become more aggressive and competitive when food is scarce, they do not typically go into a mindless frenzy at the smell of blood. They are still calculated predators that carefully assess their prey before attacking.
And i doubt sharks can actually detect a drop of blood in a swimming pool
You are correct. Despite their excellent sense of smell, sharks cannot actually detect a single drop of blood in a swimming pool. This is another common misconception that is often portrayed in movies and TV shows. While sharks can detect very low concentrations of blood in the water, it would need to be a more significant amount in order for them to detect and be attracted to it. In a large body of water like the ocean, where blood can quickly disperse, sharks may have a better chance of detecting it compared to a confined space like a swimming pool.
Is it true that a Great WHite Shark attack si often deadly is because the shark tends to attack from below, often biting off or tearing a chunk out of the humans leg, thus tearing open the arteries?
Great White Shark attacks are indeed often deadly due to the size and power of these predators, as well as the locations of their attacks. Great White Sharks typically ambush their prey from below, striking with great speed and force. When they bite, they often target the soft tissue of the torso or limbs, which can result in severe lacerations, trauma, and damage to blood vessels. If a vital artery is severed during the attack, it can lead to rapid blood loss and potential death.
It is important to note that while Great White Shark attacks on humans do occur, they are still relatively rare. Most sharks do not view humans as prey and attacks are often a case of mistaken identity or curiosity. However, given the size and power of Great White Sharks, any attack can be extremely serious and potentially deadly.
