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
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.
In what ways are fish bladders and buoyancy compensator vests similar?
as they fill or release air it will control where you are in the water. It is a lot harder for a fish, the fish have to get the air from their blood stream because they do not have lungs. Taking in air is harder because it is via their blood and they cannot release the air as fast as buoyancy compensator vests. Include all of this information and you should do fine. :3 your welcome btw
Which animal backbone is made up of cartilage?
There are two subclasses of cartilaginous fish. Elasmobranchii and holocephali. The subclass elasmobranchii encompasses sharks. The subclass holocephali encompasses rays and skates.Sharks, skates, and stingrays.
How do chondrichthyes move in the water?
Chondrichthyes, or cartilaginous fish like sharks and rays, move in the water by using their powerful tail muscles to create thrust and propel themselves forward. They also have streamlined bodies and pectoral fins that help them maneuver and control their direction as they swim. Additionally, some species of chondrichthyes can adjust the position of their pectoral fins to generate lift and maintain buoyancy.
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.
Why do sharks have large livers?
to help keep buoyancy
Why do sharks have oil in their livers?
to help the shark stay afloat
What does a nautilus use to control its buoyancy?
A nautilus uses gas-filled chambers in its shell to control its buoyancy.
How do I control my buoyancy as I ascend after a dive?
release air from your buoyancy vest.
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 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.
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.
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.
How does a scuba diver become less or more bouynt?
The primary buoyancy control is by the mass of the equipment and weight-belt versus the diver's natural buoyancy and that of the suit; but divers also use an adjustable buoyancy jacket for fine control.
What are the purpose of ballast tanks?
to control the buoyancy of a submarine
In scuba diving what is a BCD?
