I need 50 shark facts.?

Question

(Great Whites only)

Answer 1

They eat people.

Answer 2

I guess I'll just list what I know and hopefully you can sort through everyone's responses to come up with 50. (Be sure to check your facts because a lot of "children" here represent their guesses as fact.
1) They mostly eat marine mammals.
2) They sometimes confuse surfers for their usual prey.
3) They close their eyes when they bite.
4) They avoid tropical waters, the Arctic and Antarctic, and prefer temperate oceans.
5) They're warm blooded -- the only shark that is. (I think?)
6) Their teeth are triangular shaped, serrated, and extremely sharp.
7) They're really grey in color.
8) Like all sharks, they have sensors along their left and right sides (called lateral lines) which allow them to sense electrical signals emitted by the muscles of their prey.
9) Their eyes are black.
10) They can be as long as 18 feet.
11) They can weigh as much as 4500 pounds (in air).
12) Some marine biologists believe they may be the only warm-blooded shark (though this is controversial).
13) They have an endless supply of new teeth and frequently lose teeth during an attack.
14) The population of American White Sharks has increased dramatically since the Marine Mammal Protection Act (1972?) has allowed the populations of prey species to skyrocket.
15) The White Shark attacks by ambushing from below and inflicting a single massive bite wound. The shark then retreats and waits for its prey to stop moving -- to be near death due to blood lose.
16) I think (but don't know) that white Sharks give birth to live young, rather than lay eggs.
17) White sharks have an excellent sense of smell and can follow a blood trail for miles.
18) White Sharks don't survive in captivity, though the Monterey Bay Aquarium managed to keep one for several weeks before releasing it.
19) White Sharks are confused by stray galvanic currents in the water and occasionally bite the underwater metal parts of boats -- especially aluminum.
20) The White shark's dorsal fin is triangular in shape, with straight edges.
21) The White Shark's tail is lunate (shaped like a quarter moon) and the upper and lower lobes have equal areas.
22) White Sharks have been caught and found to have a variety of indigestible objects in their stomachs, including automobile license plates, motorcycle tires, glass fish-net floats, pieces of surfboards, and crab-trap floaats.
23) Female White Sharks are generally larger than males.
24) The greatest concentrations of White Sharks along the California coast are found within 30 miles of the Golden Gate Bridge, in a region called "The Bloody Triangle" and bounded by Ano Nuevo Beach (where Elephant Seals breed), the Farallon Islands (where Stellar Sea Lions breed), and Tomales Bay (where California Sea Lions breed).

That's all the true facts I can remember (and I'm not really sure about #5).

Answer 3

1. They are very canabalistic. You will only find sharks schooling in the same size range. Bigger ones eat the smaller ones.
2. Male sharks have two penises (called claspers).
3. Sharks lay both eggs and have live birth.
4. Most sharks are offended when someone calls a lawyer a shark.

Answer 4

1 They have skeletons made from cartalidge.

2 They have no gill cover, so they need to keep swimming to be able to breathe.

3 They have no Swim bladders.

4 Most have very rough skin, similar to sandpaper.

5 They are more intelligent than other fish, comparable with some mammals.

6 males have claspers, to cling on to female when mating.

7 Give birth to live young.

8 Have a reputation as man-eaters.

9 Unable to survive in fresh water.

10 Closely related to rays.

11 Most living sharks have electro-sensative pitts on their snouts, and are capable of detecting minute electrical signals from prey.

12 Most living sharks have an accute sense of smell.

13 Many living sharks store lipids (oils and fats) around their livers, to help them stay bouant.

14 Being unable to float naturally, sharks have to swim all the time and as a result are far more hydrodynamic than other fish species.

16 Great white sharks rarely attack humans because our bodies do not support the amounts of fat that their diets require. they favour seals, sea lions, dolphins, and sometimes whale carrion.

17 Bull sharks are the only species which come close to matching the great white sharks reputation for ferocity.

18 Unusually among fish, males and femals have a full set of genitals similar to that of mammals.

20 Great whites prefer to stick to warm coast lines, where their favoured prey is found.

21 there have been sightings of great whites around the UK, but since none have been caught their presence has not been made official.

22 Great whites are found in all the oceans of the world, at all latitudes.

23 They are able to use their diet to maintain their body temperature, and hense survive in arctic conditions.

24 They use their rough skin to generate a layer of turbulence over their skin, which acts as a lubricant to allow the surrounding water to pass them faster, and hense allow them to swim faster.

25 The genus to which the great white belongs once had another member. During the last ice age there was a great white shark subspecies three times larger than the living sharks. this animal was an open ocean creature capable of single-handedly killing adult whales. Reported sightings of this animal continue around australia and tasmania. "Charcharodon Megalodon".

26 Like most fish, sharks have a line of fine sensors along their side, which allows them to detect movements in the water from great distances away.

27 Weighs around 8 tonnes.

28 6 Meters long (ish)

29 Often blamed for the slaughter of surfers of the australian coast, though usually tiger sharks are the real culprits.

30 Appeared in 4 "jaws" movies.

31 Appeared in "the deep blue sea", where the sharks genetic structure was altered to produce material for brain tests. Labeled in the film as a Mako, this seems unlikely considering their size.

32 Tail evolved to generate thrust and lift.

33 pectrol fins evolved to hold body at an agle to oncoming water, to keep the shark afloat.

Sorry, thats all i can think of off the top of my head. Good luck!!
