Not that I know of. They have rough "skin".
Sharks do not have bones.They have cartilaginous skeletons.Sharks are not in the same group as bony fish; they have cartilaginous skeletons. (I.e.: not true bones.)
no. cartilaginous fishes are sharks and rays.
Jawless fish are cartilaginous, but they do not have jaws. Class Chondrichthyes, which contains most cartilaginous fish, like sharks, have powerful jaws.
Similar to Stingrays, skates are cartilaginous.
it is the cartilaginous fish.s
Both jawless fish and cartilaginous fish have skeletons made of cartilage.
Jawless fish and cartilaginous fish have cartilaginous skeletons, and bony fish have skeletons made from bone. Cartilaginous fish and bony fish both have jaws, paired appendages, and whole vertebrae, and jawless fish lack jaws, paired appendages, and often are without whole vertebrae. Cartilaginous fish can have scales or be naked, jawless fish are naked, and bony fish have scales. Bony fish have swim bladders, and cartilaginous fish do not. Jawless fish, cartilaginous fish, and bony fish all have fins, gills, and dorsal nerve cords that lead to a distinct brain. They all also have postanal tails and notochords.
When is a wall like a fish? When it is scaled! The humour here lies in the different meanings of the word "scaled". A fish is covered in scales and so is therefore scaled, and a wall can be scaled (or climbed).
Lizards are not bony or cartilaginous fish, they are reptiles.
Cartilaginous fish have cartilaginous endoskeletons, meaning their skeletons are made from cartilage. Cartilaginous fish can also have placoid scales, or they are naked. Cartilaginous fish have gills, paired appendages, strong jaws, notochords, a dorsal nerve chord that leads to a distinct brain, and lack a swim bladder.
yes
Cartilaginous fish are mainly sharks and rays. They feed off bony fish, such as goldfish.
