Verified step by step guidance1
Understand the key differences between bony fish and sharks. Bony fish belong to the class Osteichthyes, while sharks are part of the class Chondrichthyes.
Recognize that bony fish have a swim bladder, an internal gas-filled organ that helps maintain buoyancy, which is not present in sharks.
Identify that both bony fish and sharks have gills for respiration, so gills are not a distinguishing feature.
Note that sharks have mineralized teeth, but bony fish have a different dental structure, so mineralized teeth are not exclusive to bony fish.
Understand that both bony fish and sharks have a lateral line system for detecting movement and vibrations in the water, so this is not a unique feature of bony fish.
