Question

what are the adaptations of profundal zone

Answer 1

The profundal macrofauna is therefore characterized by physiological and behavioural adaptations to low oxygen concentration. Chironomidae and Oligochaetae often dominate the benthic fauna of the profundal zone because they possess hemoglobin like molecules to extract oxygen from poorly oxygenated water.
