Korte beschrijving
Determinatiesleutels | Morfologie | Morfometrie
Dorsale stekels (totaal) : 2; Dorsale zachte stralen (totaal) : 32 - 38; Anale zachte stralen: 31 - 36. Scales small with numerous tiny spinules, prominent first dorsal spine above eyes (Ref. 9002).
Body shape (shape guide): short and / or deep.
Inhabits rocky weedy areas from the shore to at least 60 m. Generally solitary but may aggregate in groups of 10-15 individuals in midwater. Feeds mainly on sessile and encrusting organisms, with sponges and ascidians predominating (Ref. 26966); also seen feeding mid-water on zooplankton and likes to bite diver's fingers (Ref. 9002).
