DescriptionThe planehead filefish grows to a maximum length of {{convert|27|cm}} but is more typically about {{convert|17|cm}} long. The colour is cryptic, being a more or less mottled pale brown, olive or green on a light coloured background, sometimes with darker brown splotches and streaks. The fish is laterally compressed and deep bodied. The snout is elongated with a terminal mouth. The large yellow eye is set high on the head and above it is a prominent retractable spine. This is the anterior of the 2 spines associated with the long dorsal fin, which also has 29 to 35 soft rays. The anal fin has no spines and between 30 and 35 soft rays. The pectoral fins are small and the tail fin is large and fan-shaped, often with two darker coloured bands.[2][3][4] Distribution and habitatThe planehead filefish is found in the Atlantic Ocean at depths of up to {{convert|300|m}}. Its range extends from Nova Scotia to Uruguay in the west and from the Canary Islands to Angola in the east. It is found near the seabed on reefs and over sandy and muddy sea floors. It is often found among Sargassum seaweed.[2] BiologyIn the Canary Islands the growth and ageing of the planehead filefish have been studied. Spawning takes place in the summer and the age of the fish is established by using the fast and slow growth rings found in the anterior dorsal fin spine.[5] The species has a lifespan of about three years and reaches half its final length by the end of its first year.[5] UsesThe planehead filefish can be used for human consumption. In the Canary Islands it is caught in fish traps and at one time was considered to be a by-catch, incidental to the capture of other, more desirable fish. However, since the 1980s, it has become a target species in its own right and by 2000, there were concerns about overfishing.[5] References1. ^1 {{cite WoRMS |author=Bailly, Nicolas |year=2010 |title=Stephanolepis hispidus (Linnaeus, 1766) |id=127409 |accessdate=2012-01-04 |db=}} {{Taxonbar|from=Q2803497}}2. ^1 Stephanolepis hispidus (Linnaeus, 1766) FishBase.
