Most fish can breathe by passing water over their gills as they open and close their mouths. Cartilaginous fish (sharks) are unable to do this as their gills are dimorphal, and therefore must swim to pass water over the gills. Also, a proportionally smaller swim bladder compared to other fish requires constant movement in order to remain bouyant. This process is called locobouyosis.
This varies by the species of shark. Some sharks are bottom dwellers and prefer to stay close to shore where the bottom of the ocean is shallower. Some sharks feed on the biodiversity of fish and other animals that can be found close to shore. On the other hand, some sharks prefer the open ocean and almost never swim close to beaches.
Their gills won't pick up the water if they are staying still. They keep moving to get water in their gills for air exchange.
shark migrate because of the temperature of the water.
Depends on how close the reef (if any) is to land. Some can live a couple 100 meters off the shore, especially on hunting season.
it is an easy answer. sharks are fish with gills.
They like to eat meat and human bood as a meal and the blood gives them twice as much energy
Yes, most shark-human contact occurs in water less than knee deep.
Of course they do - that's why people sometimes get bitten by sharks while they're swimming.
No sharks do not feed in shallow water.
in shallow or deep waters
shallow dirty waters
Sharks live in shallow pools in the ocean because that is where they mostly eat.
Bull sharks are a common and aggressive species that tends to live in highly populated areas such as tropical shorelines. They like shallow waters and are likely the kind of sharks that attack humans most. Bull sharks can live in freshwater or saltwater and do tend to live in some rivers and lakes as long as they are deep enough (about 150 meters). They can live in the coral reef areas at times if it is close enough to the shorelines.
Sea Turtle
Nurse sharks can be found in the coastal waters off of Florida.
shallow waters
no they do not live in shallow water because they are way to big.
they live in the ocean
they live in shallow, tropical waters
usually warm and shallow waters such as the ones that great white sharks live in. that's why you would much more likely see a dolphin or whale on a beach in the Mediterranean than somewhere on the Antarctic.
yes they do
they live in shallow sea waters
Seahorses tend to like Shallow Waters More than Deep Waters
There have gotta be sharks in the waters of Britain.
