Heyaa...

General characteristic features of superclass Pisces (Fish)

They are the first jawed vertebrates and the study of fish is called Ichthyology.

They are aquatic (may be fresh water or marine).

Fish are cold blooded animals (poikilothermic).

Their body is spindle shaped or streamlined to enable them to move rapidly in water.

Locomotion by paired pectoral and pelvic fins along with median dorsal and caudal fins, supported by true dermal fin-rays.

Hope it helps ❤️❤️
