otherwise they drown
Sharks love to swim. So other than eating and hunting fish, they swim. If they dont do that than they just hunt and eat all day.
sharks have to swim at all times. if they stop moving, no oxygen can pass through its gill slits for the shark to breathe.
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.
All sharks can swim regardless of age. Once a shark is born, it must swim in order to breathe. Interesting fact, sharks only sleep for a few minutes at a time because they have to wake up and swim around to breathe again.
no whale sharks do not bite.they may seem big and scary but people from all around the world swim with whale sharks.
no they dont shed but sharks skin some times fall off in fights or stuff like that if its a sharks
They all swim and live underwater
Sharks do not have the ability to pump water across their gills, therefore they need to continue swimming to move water across their gills so they can breath
Sharks live all around the world but most of them are in warm water.Actually as I learnt that sharks can swim in any ocean, cold or warm. Also, it depends on the type of the sharks.
The swim bladder is in animals that need something to help control their buoyancy. Sharks do not have swim bladders because they do not need this.
The Ocean. Like most sharks the Great White must keep moving all the time to keep its gills working to supply constant oxygen.
Sharks swim all over the world, mostly in oceans, but, the bull shark can swim in rivers. Most of the oceans, beyond the Continental shelf, are deep barren wastelands. Since most sharks live in the oceans, most of their habitat will be barren, but, not all of it. They can be found in salt waters that are teaming with life.
