The remaining 52.2 per cent is marine fish, of which 39.9 per cent live in the coastal waters of warm seas and oceans, 5,6% – in cold coastal waters, 6,4% are deep-sea bottom and bottom-dwelling (benthic) species, 5% of deep-sea pelagic and 1.3% live far from the coast in the upper 200 m of the water column of seas and oceans (epipelagic species).
