they are the only freshwater sharks
because they are very very agreasive and did you know its the only shark that can live in salt water and fresh water
No, they like cold water, but there are many dangerous shark in the pacific they attack more frequently. Such as Tiger shark. Did you know the bull shark can live in fresh water.... it likes warm water....
Contrary to popular belief the bull shark is actually the most dangerous shark, with its ability to live in fresh waters and salt water the bull shark is increasingly being found in rivers presumed to be shark free. The bull shark is wildly changeable and can be incredibly aggressive. Many Marine specialists believe the bull shark is in fact responsible for many attacks that were blamed on white sharks particularly in Sydney. The bull shark is often found in very sallow water thuds is thought to be immensely dangerous to humans The top three most dangerous shark are thought to be bull sharks great whites and tiger sharks. Most likely, the bull shark. Great whites can be dangerous, but they do not attack as frequently as bull sharks. Bull sharks can even go in freshwater and shallow waters.
The only know shark that prey on catfish is the Bull shark (Carcharhinus leucas).
bull sharks do have a brain they know no to attack a whale
The commonly known example is the penguin. It has a suborbital gland that converts sodium chloride out of the bloodstream where it's excreted as a brine on the bill. Penguins don't actually drink salt water, but they ingest it while swallowing prey.
the polar bear cuz the shark cant fight on lad. OR the shark cuz the bear cant fight in water SO The world may never know.
NONE, there have been no sharks in any of the great lakes. That's because there has to be a river attached to an ocean, and there are no salt water rivers attached to the great lakes. But Bull sharks have been known to go into fresh water to have their babies so watch out if you are in the Mississippi River because they have been found there, and they are the MOST dangerouse shark in the world!
Only 43 species of elasmobranch in ten genera and four families have been reported to enter fresh water, of which the bull shark is the best known. Other species that enter rivers include the stingrays (Dasyatidae,Potamotrygonidae and others) and sawfish (Pristidae). Some skates (Rajidae), smooth dogfishes (Triakidae), and sandbar sharks (Carcharhinus plumbeus) regularly enter estuaries. The ability of elasmobranchs to enter fresh water is limited because their blood is normally at least as salty (in terms of osmotic strength) as seawater, through the accumulation of urea and trimethylamine oxide, but bull sharks living in fresh water reduce the concentration of these solutes by up to 50%. Even so, bull sharks living in fresh water need to produce twenty times more urine than those in salt water.[5] Initially, scientists thought the sharks in Lake Nicaragua belonged to an endemic species, the Lake Nicaragua shark (Carcharhinus nicaraguensis). In 1961, following comparisons of specimens, the Lake Nicaragua shark was synonymized with the bull shark.[12] It had been presumed that the sharks were trapped within the lake, but this was found to be incorrect in the late 1960s, when it was discovered that they were able to jump along the rapids of the San Juan River (which connects Lake Nicaragua and the Caribbean Sea), almost like salmon.[13] As evidence of these movements, bull sharks tagged inside the lake have later been caught in the open ocean (and vice versa), with some taking as little as 7-11 days to complete the journey.[12] Bull sharks have been caught approximately 900 miles up the Mississippi River, and have been observed approximately 2,500 miles up the Amazon River.[14]This information is quoted from www.wikipedia.org, I did not write anything of this not did I personally gather the accumulative information to come to these scientific conclusions, i hereby do not take credit for this information, if you wish to know more about bull sharks, please visit wikipedia.org, its usually a good place for information, especially in biology. Thank you:)
The Real Answer To Your Question Is No. Jaws the shark off of the movie was a machine but it wasn't a great white the true thing it was is a bull shark. I know this cause when i was watching tv about sharks a Shark Study er Told me that "The Shark off of the movie Jaws is not the Shark you think it is its actually a bull shark"
Actually we dont there just known from jaws probably. But what we know now is that a Bull shark is the most dangerous out of all sharks even the great white. hope this helped
Tail,torpedo like body that helps it slip through water, plane like fins, and a special dorsal fin. Glad I could help. I know lots more if you need more help :)
