However, when near sharks in the water, it is wise that you do not panic as sharks can detect the heartbeat of their prey.Sharks have been known to attack humans when they are confused or curious. If a shark sees a human splashing in the water, it may try to investigate, leading to an accidental attack. Still, sharks have more to fear from humans than we do of them.Learning is closely involved with memory, and the sharks I had under observation frequently showed their ability to remember events far back in time. Familiar sharks recognized me in the lagoon as much as two years after their last meeting with me, and their behaviour, of greeting and swimming with me, was unchanged.

By all accounts, sharks have pretty impressive eyesight. As a matter of fact, it is estimated that shark sight is about 10 times better than what humans have in clear water. The structure of shark eyes is very similar to that of human eyes, comprising of a cornea, lens, retina, iris (which is a deep blue) and pupil.
Can sharks be friendly
It's true, there are sharks out there that are cute and friendly! Of the over 500 species of sharks, only a handful of them have been known to attack humans and even these attacks are mostly a case of mistaken identity. This blog explores some of the 5 friendliest shark species in the oceans.So while it's unlikely that sharks can read our minds and know when we're in trouble, they can sense distress in other aquatic animals and respond accordingly. While we may never know for certain if sharks can sense our fear of them, they certainly have that effect on us.Movements and actions, such as stiffening up or staring straight at dogs, can be seen and interpreted by dogs to lead to a conclusion that a particular person is afraid and therefore may present a threat. Rather than smelling fear, it's probably more accurate to say that dogs can sense fear. A recent study found that dogs are actually able to tell if a human is stressed or calm based on their scent alone opens in a new tab . What they choose to do with that information — run and hide, snuggle close, or attempt to initiate play — depends on their training and their relationship with said human.
Has a shark ever eaten a full human : He was diving near the reefs at Cape Howard in New South Wales in January 2007 looking for abalone, a type of edible sea snail, when the beastly shark swam up to him. The seasoned diver, who was 41 at the time, found himself inside the stomach of the 10ft-long shark as its piercing teeth sunk into his flesh.
Has anyone survived a shark bite : Mike Coots was surfing with his buddies near his home in Kauai when he was attacked by a shark. He lived to tell about it—and here's what he learned. Let's face it: Shark attacks are riveting. Plenty of people plan their lives around Shark Week—and even screenings of Sharknado.
What happens if a shark is circling you
As the shark swims around you, keep your head on a swivel and try to maintain eye contact. “Sharks are ambush predators,” Peirce explained. “If you're turning around and facing it the whole time while it circles you, it's not going to be half as comfortable as if it's able to sneak up from behind.” Stay calm and do not make sudden movements. When you first spot the shark, chances are it will swim away without bothering you. You cannot out-swim a shark, so trying to sprint to safety may not be your best option, unless you are already very close to shore.There are many harmless sharks that are perfectly safe to swim with. One of the most common and least dangerous sharks is the nurse shark. Nurse sharks are docile sharks and they grow to a maximum of 15ft long, compared to the equally-as-gentle whale shark (which can grow to around 62ft)!
How can sharks sense you : In addition to those we have – sight, hearing, touch, smell and taste – sharks have two other senses, mediated by specialized receptors: electroreceptors and lateral lines. A shark's most acute sense, the one it may use to detect prey from the greatest distance, is probably its sense of hearing.
