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
There are bony fishes and cartilaginous fishes.
yes. bony fish (class osteichthyes) have a vertebral column and a bony skeleton. cartilaginous fish (class chondrichthyes) have a vertebral column as well but their skeleton is made up of cartilage.
Ray-finned fish have "true" bone skeletons, where as the cartlaginous fish have...cartilage instead of bone as their skeletons.

Fish are vertebrates as they have an internal bony skeleton and a spine.

Bony fishes.
A perch has a bony skeleton, which is characteristic of most bony fish (Osteichthyes). This type of skeleton is made primarily of bone rather than cartilage, providing structural support and protection for the fish's internal organs. The bony skeleton also aids in buoyancy and movement in the water.
No, skate fish are not classified as bony fish; they belong to the group known as elasmobranchs, which includes rays and sharks. Skates have a cartilaginous skeleton, meaning their bodies are made of cartilage rather than bone. This distinguishes them from bony fish, which have a skeleton primarily composed of bone.
