Because those posts you reported are really offensive/off topic/annoying right? :icon_rolleyes:

I watched the top 10 shark attack videos on discovery channel's website on Sunday.
Then when I went to the beach on Monday I was scared to go in the water at first. :icon_redface:

Impressive ^^

Here is mine on whale sharks

Besides its size, the whale shark is also named for its feeding habits. Despite having teeth, the whale shark does not rely on its teeth to feed. Instead, it is a suction filter feeder - it sucks in a huge volume of water and plankton. The water is strained through spongy tissues supported by cartilaginous rods between the whale shark's gill arches. The plankton, trapped in the gill rakers, is then swallowed. Sometimes larger fishes - such as mackerels, anchovies, and tunas - are sucked in as well. A whale shark can filter 1.5 million liters (400,000 gallons) of water an hour when feeding.

Off Topic. Beside I'd rather not get the mod mad. And that isn't a surprise as some people were actually afraid of water because of the movie Jaws which in fact gives a false representation of the great white. Most attacks on humans are accidents unless by certain sharks like the mako or tiger. Great Whites are actually afraid of humans.

I got a question about sharks... Do they digest the water for purposes like humans do?

You realize that said shark is considered extinct right? If for a fact it still exist our only worries is getting in it's way. Beside if such a amazing creature still was alive I think it would be the discovery of a lifetime ^^ Though lucky for us let us hope it doesn't exist still even if the idea would be amazing.

Agreed ^^

The biggest great white shark on record was 23 feet (7 m) long.
- The great white shark has 3,000 teeth at any one time. A white shark may grow and use over 20,000 teeth in its lifetime.
- Most great white attacks are not fatal.
- White sharks cannot swim backwards but they can jump out of the water.
- No one knows the life span of the great white shark.
- Great whites do not chew their food.
- Although it is not the largest shark, the great white is the largest predatory shark.

Some fun facts about Great Whites ^^

As sensational as shark attacks are in newspaper headlines, the reality is that you're more likely to be bitten by another person than a shark. (Count down the 5 most dangerous sharks.)

95. While many people fear sharks and think of them as one of the world's most aggressive and deadly animals, the chances of dying from a shark attack fall well below the chances of being killed by hornets, wasps, bees or dogs. (Count down the 5 biggest shark myths.)

94. A few of the known shark species will drown if they stop moving. Great white, mako and salmon sharks don't have the muscles they need to pump water through their mouth and over their gills. As long as they keep swimming, water keeps moving over their gills, keeping them alive.

From what I know from A level biology, shark is a fish of course. And from what I know about fishes, they do not use the water in the same way as humans. Instead they have a brilliant system in their gills to extract the oxygen from the water and use it as respiration purposes.

Of course, both fish and mammals (humans, as that's what we're talking about) respire, as I have said, but both use water for different purposes.

Humans need it to carry nutrients and waste in the body, to lubricate joints, digestive tract and body tissues and to cool the body, especially during periods of physical activity. Whereas fish use it to, quite simply, breathe.
