If sharks are so evolutionary advanced and such killing machines, how do they confuse surfers with seals??

Question

They say that sharks attack humans of sruf boards because from underwater they look like seals and food they normally eat. Sharks are considered to be very intelligent and i don't doubt that, but why are they making this mistake?

Answer 1

Hi,

sharks have sensory organs on their nose to pick up electrical signals, such as those generated by muscles when moving. Often the shark that attacks a human will make only one bite and then go away. This behaviour has many possible explanations, one being that humans don't taste good (or at least, as good), or are lacking the necessary fat, and another being that sharks normally make one swift attack, and then retreat and wait for the victim to die, or exhaust itself, before it comes back to feed. This protects the shark from injury, especially tooth loss, from a wounded and aggressive target; however, it also allows humans time to get out of the water and survive. Another theory is that the electrical receptors, which pick up movement, do not pick up the same signals from a wounded human as they would a wounded seal, and so they are more cautious. In fact, it has recently been shown that surfers do not give off the same electrical signals as seals, or it is thought there would be far more attacks.

So as it goes, we have hands to touch and feel things, sharks do not and only have their noses which means a mouth full of razor sharp teeth.

From below, surfers have a silhouette that's very similar to a seal's, so it's not hard to make a mistake. Otherwise the shark is simply curious. Rarely do sharks actually eat people. Usually an attack just involves an "investigative bite". The shark bites, discovers this strange critter flailing inelegantly in the water is bony and lacks much tasty fat and flesh and is not worth eating, then they spit the yucky thing out and swim off. Sharks bite anything they are interested in to see if it's edible. As a result, they can accumulate some strange things in their stomachs.

I'm not sure where you're getting your information from but sharks are not evolutionary [sic] advanced nor are they very intelligent. They are very ancient creatures who have not changed much in many thousands of years. In fact, they're one of the least changed animals on the planet. The have very small brains and are not intelligent animals.
They are instinctive animals and are drawn to particular cues which tell them where food might be found. Cues for sharks are things like blood in the water, thrashing sounds, magnetic fields (generated by living creatures) and outlines of typical prey items. When carefully considering their prey, often sharks will inspect the prey before biting and will determine that the cue does not actually represent real prey (such as a shark drawn to a metal item with a magnetic field and turns away determining that the item is not food). In some cases, such as that with a great white, the prey capture is dependent highly on a quick strike which disables the prey and allows the shark to move in for the kill as the prey flounders helplessly. Such an attack does not allow for the shark to inspect it's prey prior to attacking which leads to sharks attacking surfboards or other items on the surface which may resemble the same shape.

The action picture "Jaws" is what did interior the sharks. Now anybody thinks that they do no longer something yet circulate around killing each thing that they arrive in the time of. additionally, because of fact of that action picture, anybody thinks that that's their accountability to kill sharks on each occasion they are able to and sharks are being pushed to extinction because of fact of it. give up KILLING SHARKS! No, the lions did no longer kill Daniel. He grew to become into thrown into the lions den because of fact the King's ministers tricked the king into passing a regulation that they might use especially against Daniel. The king threw him into the den because of fact, as king, he had to obey regardless of regulation he signed. He did so unhappily hoping that Daniel's God might shop him. God closed the lions mouths and that they did Daniel no harm in any admire. The king grew to become into extremely joyful day after as we communicate to be certain that Daniel grew to become into nonetheless alive. Daniel grew to become into pulled out of the lions den and the jealous king's ministers have been thrown in as a substitute. They have been all killed in the present day by using the lions.

Answer 5

Nature makes no mistake and is infallible. It does precisely what it means to. A shark's only goal is to provide itself with sustenance and humans are a valid source of food for them.

Answer 6

Hi. Sharks kill instinctively. They do not make a decision or taste first.

Answer 7

um, they are fish.
