The ray-finned fishes are characterized by?
The ray-finned fishes are characterized by having fins supported by bony spines or rays. They also have a skeleton made of bone, scales covering their bodies, and a swim bladder for buoyancy control. Ray-finned fishes are the most diverse group of fishes, with over 30,000 species.
What does the swim bladder do?
The swim bladder is an internal gas-filled organ in fish that helps them control their buoyancy and maintain their position at different water depths. By adjusting the amount of gas in the swim bladder, fish can move up or down in the water column without wasting excessive energy on swimming.
What is the function of the swim bladder in bony fishes?
The swim bladder in bony fishes helps control their buoyancy by regulating the amount of gas inside it. By adjusting the volume of gas, fishes can ascend or descend in the water column without expending much energy.
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.
Where do cartilaginous fishes store oil?
Cartilaginous fishes store oil in their large, oily livers. The liver serves as a buoyancy aid, helping these fishes control their depth in the water column. Additionally, the oil stored in the liver provides a concentrated energy reserve for these species.
