Pelagic fish

A school of large pelagic predator fish (giant trevally) sizing up a school of small pelagic prey fish (anchovies)

Scale diagram of the layers of the pelagic zone

Large epipelagic predator fish, like this Atlantic bluefin tuna, have a deeply forked tail and a smooth body shaped like a spindle tapered at both ends and countershaded with silvery colours.Small epipelagic forage fish, like this Atlantic herring, share the same body features listed for the predator fish above

Herring reflectors are nearly vertical for camouflage from the side.
