cartilaginous fishes have lamelliform gills. bony fishes have filiform gills.
A bony skeleton. Snappers are a member of the taxonomic group Osteichthyes (bony fish), as opposed to cartilaginous fishes (like sharks) or boneless fishes (like hagfish).
Bony fish have a bony skeleton that provides more support and protection compared to the cartilaginous skeleton of cartilaginous fish. Bony fish also have a swim bladder, which helps with buoyancy control, allowing for more efficient swimming. Additionally, bony fish have scales that provide further protection against predators and environmental factors.
cartilaginous fish are in fact very similar to humans in that we both take in oxygen and release carbon dioxide. the difference is that cartilaginous fish breathe through their gills (slits along neck) by contracting and relaxing.
They belong to the bony fish category. See the related link.
There are bony fishes and cartilaginous fishes.

Jawless fish, cartilaginous fish, and bony fish.
A bony fish is a fish that has a skeleton made of bone, with less cartilage than a cartilaginous fish. All bony fish can breathe both salt and fresh water. A good example of that is the Pacific salmon.

The upper jaw of a cartilaginous fish is not attached like it is in bony fish, although both sets of jaws work in the same way. Bony fish have a protective bony plate that covers the gills. Cartilaginous fish lack this covering but have their own way of protecting the gills.

Sharks and Rays belong to the class Chondrichthyes, the cartilaginous or non-bony fishes.
Placoid scales are found in cartilaginous fishes and can be dermal or mesodermal in origin whereas cycloid scales are the bony scales found in bony fishes that are always mesodermal in origin.
Lizards are not bony or cartilaginous fish, they are reptiles.
