Cartilaginous fish such as sharks, skates, and rays are vertebrates, whose internal skeleton is made entirely of cartilage and contains no ossified bone. Cartilaginous fish are also known as Chondrichthyes and have one or two dorsal fins, a caudal fin, an anal fin, and ventral fins which are supported by girdles of the internal skeleton.
One example of a cartilaginous fish is the shark. Sharks have skeletons made of cartilage rather than bone, distinguishing them from bony fish, which have skeletons made of bone.
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.

It is as primitive as a cave man.
Hagfish are cartilaginous, meaning their skeletons are made from cartilage. FALSE what the person just wrote is wrong. Hagfish are neither cartilaginous or bony fish. Although they have cartilage in their bodies, they belong to a third category called Jawless fish. Jawless, cartilaginous, and bony are the 3 types of fish.
Sharks are not bony fish. They are cartilaginous fish.
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.

it is the cartilaginous fish.s
Similar to Stingrays, skates are cartilaginous.
No, sorry that's quite false. For a great example consider a great white shark. It's a cartilaginous fish.
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.
Both jawless fish and cartilaginous fish have skeletons made of cartilage.
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.
Lizards are not bony or cartilaginous fish, they are reptiles.
yes
