The plural form of "permit" is "permits."
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... :)
This is actually not true at all times or for all sharks. It is true that most sharks need moving water in order to breathe, but there are underwater currents where sharks can stop, because the water is moving around them.
they keep moving
Suffocate if they stop moving
Sharks die when they don't move, so even though they rest, they don't stop moving!
Walking on the seabed
Sharks can never stop moving, because of the way their gills are. If they stop swimming, water will get in, and they will drown and die.
Whale sharks are slow moving plankton filter feeders. So would not eat crabs.
Sharks swim by moving their bodies from side to side, which propels them forward. They use their powerful tails to generate thrust and their pectoral fins for steering and stability. Sharks are highly efficient swimmers and can glide through the water with minimal effort.
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.
yes or they can drown and die if they sink
