Siganidae (Rabbitfishes)
Etymology: Siganus: Latin, siganus = a fish, rabbit fish; by the similarity of the nose (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Ecologia
marino associati a barriera corallina, usually 3 - 30 m (Ref. 27115). Tropical; 24°C - 28°C (Ref. 27115); 15°N - 25°S

Max length : 24.0 cm TL maschio/sesso non determinato; (Ref. 9710)
Spine dorsali (totale) : 13; Raggi dorsali molli (totale) : 10; Spine anali: 7; Raggi anali molli: 9; Vertebre: 23. Color dark purplish brown except pectoral fins, soft portions of dorsal and anal fins, caudal fin, and posterior part of body; demarcation of 2 colors is sharp. Preopercular angle 110°-114°; strong overlapping scales cover cheeks, 9-10 rows deep below center of orbit; midline of thorax fully scaled. Spines stout, pungent and venomous.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00650 - 0.03213), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.7 ±0.30 se; based on food items.
Resilienza (Ref.
