Difference Between Bony Fish and Cartilaginous Fish
The difference between bony fish and cartilaginous fish is the study of all the differences that make the two groups of fish separate. Bony fish and cartilaginous fish are two diverse groups of aquatic vertebrates. Bony fish and cartilaginous fish both share certain similarities like the presence of gills and fins. But bony fish and cartilaginous fish are fundamentally different, based on their skeletal structure.
Bony fishes have a bony skeletal system due to which they are called so whereas cartilaginous fishes have a skeletal system made of cartilage due to which the group derived its name. In this article, we will look into the general characteristics of bony and cartilaginous fishes and their characteristic differences and similarities.
