Hello Friends ✌
Here is u r Ans ➡
✨Technically, the most obvious disparity between bony vs cartilaginous fish comes from the fact that the skeleton of bony fish is made of bones alone, while that of cartilaginous fish is made of cartilage. There are more than 20,000 fish species in the world. Of the class Chordata, Pisces is a super class.
