No one organ gives it buoyancy, especially since they don't have a swim bladder. If a shark stops swimming, it will sink.
Since they don't have a swim bladder, they maintain it by simply moving through the water. If they stop moving, they will eventually sink because of their weight. Their liver is important, as they have an oily liver that may make up to 25% of their own total mass.

How do sharks control their buoyancy?
Some sharks swim by propelling themselves through the water using their tails, like great white sharks. The fins are only used for balance. Other sharks, like the whale shark, move their bodies from side to side to propel themselves through the water.
Why do sharks have oil in their livers?
to help the shark stay afloat
What is a small organ near the sharks liver that stores bile?
what is a small organ located near the shark's liver; that stores bile
Are sharks cartilaginous fish?
Yes, sharks are cartilaginous fish, meaning their skeletons are made of cartilage rather than bone. This cartilaginous structure allows sharks to be more flexible and lighter, which is beneficial for their buoyancy and swimming efficiency.
Bony fishes have a gas-filled organ which is called?
Bony fishes have a gas-filled organ called the swim bladder. This organ helps them to control their buoyancy and maintain their position in the water column by adjusting the amount of gas it contains.
Why is liver the main organ for sharks buoyancy if it only gives off oil in not so large quantities while stomach can hold and compress air and use them like submarines?
Liver is much larger in sharks as compared to stomach.Liver not only helps in buoyancy but also keeps shark upright. there are other factors which are also involved in buoyancy.
Why do sharks have large livers?
to help keep buoyancy
What organ is absent in a shark's body?
Sharks do not have swim bladders, which are organs found in bony fish that help regulate buoyancy. This absence allows sharks to control their depth in the water column by using their large, oil-filled livers.
What is the buoyancy of a dogfish shark?
Dogfish sharks, like other sharks, have a unique buoyancy system primarily due to their large livers, which are filled with oil. This oil is less dense than water, helping to counteract their weight and providing neutral buoyancy. Their cartilaginous structure also contributes to their ability to maintain buoyancy while swimming. Overall, these adaptations allow dogfish sharks to navigate efficiently in their aquatic environment.
Why do the fish have a swim bladder?
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.
What are 3 ways sharks can maintain neutral buoyancy '?
Sharks can maintain neutral buoyancy by adjusting their oil content in the liver to control their overall body density, using their large pectoral fins to glide and control their position in the water, and by swallowing air at the surface to increase their buoyancy when needed.
Do sharks eliminate?
yes, sharks eliminate through an organ called a cloaca.
How do they maintain buoyancy?
fish maintain buoyancy usind a organ near there gills wich fills with oxygen and keeps the fish afloat
What do sharks lack that makes them different from many other fish?
Sharks have no swim bladder for buoyancy. Instead, an oily liver aids in bouyancy.
How are fish capable of floating?
they have an organ called a swim bladder. it is a buoyancy device
What organ do sharks not have that that bony fish have?
swim bladder.
What is the name of the sensory organ used by sharks to detect electric impulses?
lateral line organ
