Description

Also known as Leatherjacket, Rough Leatherjacket, Triggerfish, Triggerfish Durgon, Unicorn Leatherjacket, Unicorn Leatherjacket Filefish, Yellow-finned Leatherjacket.

Found singly, pairs or in small schools under floating debris over shallow water drop-offs and sandflats close to deeper waters.
They feed on detritus and benthic invertebrates.
Juveniles often close to large sea jellies
Varies in colour with age.
Length - 75cm
Depth - 1-80m
Circumtropical

Filefish can alter their colour and pattern to match their surrounds and so deter predators.
Although closely related to the Triggerfish, their "trigger spine" cannot be locked into place. Ref: https://www.fishbase.se/summary/Aluterus-monoceros

    At 75 meters (as described above), this would be the longest true fish in the world. I don't want to be around a fish that is more than three quarters the length of a football field.

    Caught two of these South of Pensacola,Fl at Antares public reef in 122 ft water. Had no idea what they were and through back. Sure is one ugly fish!
