What else can I help you with?
Do sharks need air like humans?
yes, sharks take small oxygen bubles and breath them through there gills
Does a whale shark breathe from oxygen?
Like all sharks ( like fish), whale sharks breathe through gills which extract oxygen from the water.
Why do sharks die if they don't move?
Some sharks would drown but other sharks can pump water over their gills so they don`t need to swim. Some sharks lie in wait for their prey to come to them.
Can white sharks only breathe underwater?
Yes, white sharks have gills that allow them to extract oxygen from water, which is how they breathe underwater. They need to constantly swim to ensure a flow of water over their gills for oxygen exchange.
What are the biotic or abiotic factors that sharks need to live?
Biotic factors that sharks need to live include prey availability and suitable habitats for reproduction. Abiotic factors essential for sharks include proper water temperature, salinity levels, and oxygen concentrations in their environment.
Why can sharks stay under water longer than whales?
Sharks have gills to extract oxygen whereas whales , being mammals , have lungs from which they get their oxygen . Whales need to surface in order to access oxygen while a shark is not burdened with this necessity thus being able to stay underwater indefinitely .
How long so sharks hold their breath for?
Sharks can typically hold their breath for about 15 minutes to an hour, depending on the species and activity level. Their ability to hold their breath is due to their efficient respiratory system and the presence of special adaptations like high levels of oxygen-storing myoglobin in their muscles.
How do sharks survive in ocean?
They survive because they live off of dead and alive animals that live in the ocean.
Why do sharks mate?
Sharks need to mate for there to be new Sharks born.
Why must sharks always be swimming?
Sharks cannot stop moving because they always need oxygen flowing through their gills. Unlike other fish, who are able to "pulse" their gills in order to keep water and oxygen flowing through their gills, sharks are unable to do so and therefore have to keep swimming.
Do sharks need to come up for air?
Sharks need to breathe, but they don't breathe air. They use their gills to "pull"oxygen from the sea water. They need to keep moving and breathing or they will die. Go to http:en.wikipedia.org and go to sharks. It's a free encyclopedia you can use for anything. Have fun I love sharks!!! Actually sharks don't use their gills to pull in oxygen, sharks' gills cannot take in water (which has oxygen in it) without either being in motion, or resting in a current. When the water flows over the gill slits blood in the gill filaments absorbs oxygen from the water being pumped over them, which is then carried to the muscles and organs in the rest of its body. Shark's gills are not covered. There is a spiracle, which is a modified slit, just behind the eye.
How do shark's breathe I need a biology answer?
Like other fish sharks extract oxygen from sea water as the seawater passes over the shark's gills
