Coastal fish can be contrasted with oceanic fish or offshore fish which inhabit the deep. The mailed butterflyfish chaetodon reticulatus is a species of butterflyfish found at depths of from 1 to 30 metres 33 to 98 ft on reefs in the central and western pacific ocean. Coastal fish also called inshore fish or neritic fish inhabit the sea between the shoreline and the edge of the continental shelfsince the continental shelf is usually less than 200 metres deep it follows that pelagic coastal fish are generally epipelagic fish inhabiting the sunlit epipelagic zone.
