Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 13; Rayons mous dorsaux (Total) : 12 - 14; Épines anales: 2; Rayons mous anaux: 13 - 14. Bluish or purplish spots at the posterior base of the dorsal fin. Juveniles with large ocellus that reduces with size and lacks completely in adults. The white band in young reduces to a small white saddle in large adults (Ref. 48636). Body depth 2.2-2.5 in SL (Ref. 90102).
Body shape (shape guide): short and / or deep; Cross section: compressed.
Adults occur in protected inner reef flats and shallow lagoons and channels, over rubble and rocky outcrops. Feed primarily on filamentous algae (Ref. 7247). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Diurnal species (Ref. 54980; 113699).
