why does a shark always have to be moving in water
The tail fin (caudal fin) is used to propel the shark forward through the water. This is done by the shark moving the tail horizontally from side to side.
Fluid friction is the type that exists for a shark swimming in the ocean. It's related to drag force, which affects objects moving through water.
Water is always moving in some form, whether it be through the water cycle (evaporation, condensation, precipitation) or in bodies of water due to currents and tides. Even in a seemingly still body of water, there is usually some level of movement or circulation occurring.
Yes if you stay in the water without moving for awhile a shark will come up and kill you.
The fins help the great white shark steer through the water
yes I think there is a way of moving through the water. to move trough the water you need to use your imagenation
Time, for example.
Many sharks' gills are shaped in a way so that they can obtain water only when moving forward. If the shark, for some reason, stops moving forward it will begin to suffocate. The suffocation can be cancelled when the shark starts moving forward again.
Swimming helps to force water through the shark's gills, providing the shark with oxygen; the shark may not get enough oxygen otherwise.
Water has high cohesive forces
A whale shark is a filter feeder; it sifts plankton and small shrimps from the water it swims through.
What shark ever lived anywhere except the water??? I see a lot of these adaptation questions about sharks. Tell your teachers THEY NEVER ADAPTED! They have ALWAYS been aquatic animals and always will be. When a shark shows up at your door, THEN, you can study a real adaptation. Until then, sharks are designed to live in water and do it naturally.Ken, the Shark Wrangler
