The two-ton shark arrives so fast that there is little a person can do to swim away!\n\nA guy called McCosker and his co-researchers say they have interviewed every single living shark attack victim in the West Coast. \n\n"None of the living victims ever saw the shark in advance," he said. "It all happens too fast." \n\nBesides that, believe it or not:\n\nMore people get killed by falling coconuts than by shark attacks.\n\nAlltogether there are only 106 known attacks on the WHOLE West Coast!!!! \nThe only recorded shark attack in San Francisco was on May 7, 1959, when college student Albert Kogler was bitten twice -- and died -- while swimming off Baker Beach.

Sharks are fish and Dolphins are mammals. They have no scientific relationship, totally different species.

Hell yes I would no way would a shark get me in 20 sec. I've researched them for years, just get under the sark they never attack straight in front always from below and behind.

The scales- Same structure, shape, and composition- In fact, a related function, since sharks will brush the sides of their body by interesting possible food items to scrape off a little (of your skin, for example) in order to "taste" it with special sensors in the skin.  Generally, if a shark does this with a human, they will *not* attack further.

1st off the sharks are always there you may not see them but they are there I have been surfing manytimes and had a shark swim right by me fishing with live bait is not going to attract sharks un less its bigger and a very bloody bait they are attracted to large fish and bloody meat not little shrimp and shinners which is what wade fisherman use along with shrimp and such you are more likely to get worried if someone is using chicken to catch crabs then anything and then you are looking at a thigh not a whole chicken the blood could attract them but not likely I have doen it many times and not a single shark bite on my line

Most sharks are ovoviviporous with the eggs being fertilized by a male but developing internally. There would be numerous eggs all in a clump, whereas a single ostrich egg would be larger than one individual shark egg, not a clump of sharks eggs.

Bony fishes don't have eyelids. Cartilaginous fishes (sharks and rays) have a more or less developed lower eyelid thay may or may not have a nictitating membrane (a transparent extra eyelid). In any case, sharks close their eyes for protection when they bite, not for sleeping. And the upper eyelid is just a tegumentary fold.\nSee a nice illustration here (from Elasmoworld):\nhttp://www.elasmoworld.org/biology/anatomy/shark/external/diagrams/eye.gif\n\nFish sleep with their eyes open (the definition of fish "sleep" is not completely agreed upon, some researchers speak of "sleep-like behavior").\n--------------------\nKamannchie_girl, what do whales have to do with the question? You'll only confuse people if you mix whales with fish.

Yep. Dolphin attacks on humans are about as common as shark attacks. The difference is that dolphin attacks are very rarely serious enough to require hospitalisation and never fatal. As a result people know that sharks are prone to attacking humans but largely ignorant of dolphin attacks on people.\n\nIt's amazing how many people believe that dolphins won;t attack people.\n\n\nIn the past few months there have been reports of dolphins “attacking” humans that have come to interact with them. The latest are those of a 12 year old girl, a 34 year old woman, a 26 year old mother of two, and a 10 year old boy. All of these victims were not seriously injured, but were very frightened by their experience.\n\nDolphins, as well as other mammals, have a natural instinct regarding eating, mating, and social interaction. By humans coming into the world of dolphins they may interrupt the dolphins routine. This may be distressing to the dolphins, which may show this by attempting to get the human to flee, as they would with anything else they see as a threat.\n\n Further damaging a reputation tarnished by reports of violence, a bottlenose dolphin off the coast of Florida bit a 14-year-old French tourist who tried to pet it this week. The girl, who was swimming in the Intracoastal Waterway near Nokomis, Fla., suffered only minor cuts and bruises. She was taken to a local hospital, treated and released.\n\nWhile this attack certainly wasn’t fierce, local whale and dolphin experts say it may serve to accelerate a changing view of dolphins in the wild. The incident comes just months after an extensive report published in The New York Times cited similar occasions on which the seemingly friendly creatures display violence toward humans. In this case, 14-year-old Pricilla Jones was the unassuming victim. Witnesses say that Jones, a tourist from Paris, swam out to greet the dolphin and tried to pet it on the back. In response, the dolphin thrashed around in the water around her, biting her on the hand.

A mako shark is exceedingly fast. It feeds on some of the fastes tunas and billfish that otherwize would not have their populations kept in check or slower specimuns weeded out. It is an appex predator or in other words it sits at the top of it's ecological niche with nothing feeding on it. It also feeds on squid, dolphins, porpoises, Bluesharks, sea turtles, and mackerals.

YES! but that would depend on what species.\n\nsurprising to some, but NOT all sharks die when they stop moving. infact some species even tend to lie motionless at the bottom of underwater caves.\n\nCaribbean Reef Shark (Carcharhinus perezi)\nBanded Houndsharks (Triakis scyllium)\nWhitetip Reef Shark (Triaenodon obesus)\nLemon Sharks\nGrey Reef (Carcharhinus amblyrhynchos)\nBlackfin Reef (Carcharhinus melanopterus)\n\nare just a few examples.\n\nangel sharks lie motionless covered with sand on ocean floor to ambush prey.\nwhile some sharks "sleep"\n\nhope that helps :)

I've only found one reference to this behavior, and the original publication is in Russian. Orcas are social mammals and it would take extremely stressful circumstances for cannibalism to occur.

sharks are really not as dangerous as there reputations shows them to be.  more people are killed by flying toilet seats every year than sharks while we kill over 100 MILLION sharks every year.  Now to answer your question, there is no real set of rules but there are guidelines you should follow\n1. don't swim alone\n2. always keep your eye on the shark\n3. do not wear jewelry or anything else shiny\n4. try to avoid the colors orange or yellow\n5. don't panic

The sharks may avoid these fish because their ancestors learned that those fish species are poisonous or just taste awful. Predators don't eat everything, just certain species. Take birds and butterflies. There are certain butterflies that have distinct patterns that birds recognize and the birds leave them alone because they are poisonous. Other butterfly species have similar patterns because they will get left alone if they look poisonous. The shark probably looks at the fish swimming in the tank and goes "I'm not eating that, you can't make me" and they wait for feeding time.

They think it's other fish.  Light on fish scales resembles the same thing as shining on jewelry, etc.\n\nSo if you don't want to get chowed on by a shark, leave your jewelry at home, oh scaley one.

I would have to say no. Atleast not with out help from an artificial help. Man is not a water creature and the shark was born for it. A shark can swim faster than any man can run.
