Cartilagenous fishes of the class Chondrichtheis have to swim constantly as they lack swim/air bladder in them... secondly they have to swim constantly so as to let oxygen rich water flow through their gills

Answer:
There are 2 major reasons why a cartilage fish keeps swimming the first reason is to maintain their buoyancy and keep them floating, the other reason is to keep their respiratory system active.
Explanation:
Buoyancy is an important aspect that is to be maintained for keeping a sinking object to float, in bony fishes there is a buoyancy or a swimming bladder that keeps them floating inside the water.
