Ray-finned fish have "true" bone skeletons, where as the cartlaginous fish have...cartilage instead of bone as their skeletons.
cartilagenous fish - cartilagenous skeleton
bony fish - bony skeleton
the three types of fish are jawless, bony, and cartilaginous. the bony fish is made of bones, and the cartilaginous and jawless fish are 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.
Jawless fish, cartilaginous fish, and bony fish.
Who?
All fish have backbones. They are vertibrates. There are jawless, cartilaginous, and bony fish, but all have a vertebrae.
No bony fish are not extinct. Bony fish are fish with a bone skeleton unlike Cartilaginous fish which heave a cartilage skeleton and jawless fish which don't have a skeleton. -Erin 11
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.
it has two types of species the first is the jawless fish the secent is not
Both jawless fish and cartilaginous fish have skeletons composed of cartilage and distinct brains. Also, some cartilaginous fish don't have scales, and all jawless fish don't have scales. Cartilaginous fish, however, have jaws, paired appendages, and a kind of vertebrae. Jawless fish do not have jaws, paired appendages, and often are without vertebrae.
Both jawless fish and cartilaginous fish have skeletons made of cartilage.
Yes, lampreys are cartilaginous fish.
There are seven classes of vertebrates. They are the jawless fish, the cartilaginous fish, the bony fish, the amphibians, the reptiles, the mammals, and the birds. Within each group there are many species.
