Difference between chondrichthyes and osteichthyes
Answers
The main difference between Chondrichthyes and Osteichthyes is that the Chondrichthyes is the class of bony fish whose endoskeleton is made up of cartilages whereas Osteichthyes is the class of cartilaginous fish whose endoskeleton is made up of bones.
Cartilaginous fish have a skeleton made up entirely of cartilage, while bone fish have a skeleton made up of bones. Another striking difference is the gills. The bony fish have a membrane that covers the gill slits, while the cartilaginous fish have their gills exposed, without any protection.
