Rhino Filefish (Pseudalutarius nasicornis)

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

Description

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

Found singly, pairs or in small schools over silty sand slopes amongst 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
