depends on the type of shark some swim in schools like hammerheads some don't like great whites
they usually swim on their own but they sometimes swim in a group which is about 3
alone
it depends on the shark you are asking about. Most sharks want to swim alone because they want food to themselves and they are very vain. Some sharks swim in groups though. Only to be tougher then 1 shark is. But most of the time, a shark will swim alone.
don't swim at dawn or dusk don't swim alone don't swim near river mouths don't swim on overcast days
Tiger sharks are generally solitary animals, but they can sometimes be found in small groups, especially in areas with abundant food sources. These groupings typically consist of a few individuals rather than large schools. Their social behavior is not well-defined, and they primarily prefer to hunt and swim alone.
Hammerhead sharks have rows of teeth. During the day they swim in schools but they hunt alone at night.
sharks don't swim on land Do you mean oceans?
Sharks are fish. Fish swim in 'schools'. Whales and dolphins are mammals. These swim in 'pods'.
Sharks only need enough water to swim in - so you may be safe from larger sharks, but smaller ones will be perfectly capable of swimming in 4' deep water. You should always practice "shark safety" when swimming in waters that are home to sharks, for instance: - do not swim if you are bleeding - do not swim in cloudy waters where sharks may be hiding, such as around piers - do not swim near to where people are fishing (for more than just fear of sharks - you could get 'caught' yourself!!) - leave the water if wildlife in the water, such as fish, begin to behave strangely or erratically - leave the water if you spot a shark - always check with a lifeguard before you swim - do not swim alone
Dolphins are capable of defending itself in a group against preditors, but if alone I would say a group of sharks.
swim
Yes. They have to swim to keep alive.
