Rhino Filefish (Pseudalutarius nasicornis)

Also known as Leatherjacket, Rhino Leatherjacket, Rhinoceros Filefish, Rhinoceros Leatherjacket

Description

Also known as Leatherjacket, Rhino Leatherjacket, Rhinoceros Filefish, Rhinoceros Leatherjacket.

Found singly, pairs, or in small schools, over silty, sandy slopes, rubble, and seagrass beds, of sheltered lagoons and coastal reefs, rich with invertebrate growth.
They feed on crustaceans, molluscs, and worms.
Juveniles shelter in sea pens and sea-whips, often lining up vertically to hide behind sea-whips.
Length - 18cm
Depth - 1-50m
Widespread Southeast Atlantic, Indo-West Pacific

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/Pseudalutarius-nasicornis.html
