Cartilaginous fish have entirely cartilaginous endoskeletons, meaning their skeletons are made from cartilage. They also have strong jaws, paired appendages, well-developed sense organs, and hunt using a system known as the lateral-line system, which uses vibrations to recognize prey. They can have placoid scales or be naked, and they do not have a swim bladder. They have a dorsal nerve cord that leads to a distinct brain, and they have a notochord.
Bilateral symmetry
Osteichthyes are fish that have skeletons made out of bone instead of cartilage. They are usually called "bony fish".
Bilateral.
There are many animals that have the same type of symmetry as the letter M. A frog for example has this.

The reproduction among organisms in Osteichthyes varies greatly, but is all sexual reproduction with separate sexes.
One type of symmetry is rotation. The second type of symmetry is translation. The third type of symmetry is reflection.
Members of the class Osteichthyes, which includes bony fish, have an endoskeleton made primarily of bone. This type of skeleton provides structural support and protection for the internal organs. It also allows for flexibility and movement in water.
