Skin: with scales in placoid and osteichthyes scales in chondrichthyes. Respiration: branchial, Circulation: incomplete, closed, heart with two chambers. Nitrogen waste: urea in chondrichthyes, ammonia in osteichthyes. Thermal control: heterothermic. Kind of reproduction: sexual, internal fecundation in chondrichthyes, external in osteichthyes.
