The shark has the instinct that it needs to eat. A human on a surfboard looks like food to a shark because the form resembles a seal. Sharks are not very friendly towards humans and have very poor eyesight. This leads the shark to believe that almost anything that moves is food.
Sharks might eat a human or bruise him for life more like a scar
A shark will generally treat a human with passive curiosity, unless you're floundering around splashing--then they may mistake you for a seal then and take a nibble or two from you. If you have a open wound in the water, the interaction will be aggressive on the part of the shark.
Bournemouth Hants/Dorset border as in UK ? No, there are no shark nets there because there are no sharks, well there are but not of the Great White variety. You might see a Basking shark, you will see a Nursehound or Dogfish, but they wont hurt you. British coastal water will need to be very much warmer to attract tropical species of shark which might have adverse human contact.
no, all dolhpins are nice and willing to help almost any mammal. that is why japonese whalers are s.o.bs. no dolphin species is known to harm humans. many dolphin/human interactions result in the human being saved from a shark.
Really, it is neither since sharks eat humans on accident because there eye sight is so bad. However all of there other senses work perfectly well. But some sharks will eat humans if they are really hungry. But typically sharks eat humans on accident. Actually they think we taste rather disgusting.
Human Envirment Interactions means how people adapt
Some human interactions are lie food and water or oil ;)
the brain is smaller in the shark
Attacking! Most shark attacks occur, when the human is threatening the shark.
A cod is much more closely related to a shark than to a human.
Human environment interactions is the communicating of persons or villagers in one environment or community
That depends on the sise of the shark
