Sharks do not have the ability to sense HUMANS are in the water... They have a sensory that makes it able for them to sense when things are moving in the water. They do not know what you are what they see you as is food... :)
Yes they do sight,sent,hearing,taste,and touch.
A sharks special scence is smelling because some sharks can smell form miles away.
cause they don't know that they are humans they think they are there pray
To me and people who find sharks interesting yes, to you I don't know
Some people eat sharks.. i didn't know what other's do... sorry...
People should remember to get out of the water calmly and quickly when sharks are seen in their area.
If sharks did not move then they would die, when they move its like they are breathing, I know we dont do it but they are sharks ya know xD
they are the only freshwater sharks
At this stage there are no sharks in the black sea because the water is too cold for them.
about the only predator is people. unless that is you count dolphins believe it or not they are know to gang up on sharks and kill them.
sharks eat people right
Sharks only attack when they are hungry or not well fed, I don't quite know how they act if they are normal probably they will ignor you.
No there were no sharks that ate people from Titanic because. the ship sank in cold water sharks don't live in cold water they can't survive .
All sharks (except the San Jose Sharks) live in water
