Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 12; Raggi dorsali molli (totale) : 11 - 13; Spine anali: 2; Raggi anali molli: 11 - 12; Vertebre: 26. Body very dark gray-brown, depth 1.95-2.1 in SL. Caudal fin abruptly white. Narrow posterior part of dorsal and anal fins hyaline. Base of pectoral fins with a large black spot. Upper and lower spiniform procurrent caudal rays 2; upper and lower 2 branched caudal rays filamentous and often very long. Tube lateral line scales 16-18, rarely 16. Free margin of subopercle nearly reaching a vertical at rear margin of pupil.
Body shape (shape guide): short and / or deep; Cross section: compressed.
A shallow water species. Feeds on planktons (Ref. 89972). Diurnal species (Ref. 54980). 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).
