Siganidae (Rabbitfishes)
Etymology: Siganus: Latin, siganus = a fish, rabbit fish; by the similarity of the nose (Ref. 45335).

生态学
海洋 礁区鱼类; 深度上下限 2 - 40 m (Ref. 12382). ; 35°N - 35°S
Western Indian Ocean: Persian Gulf (Ref.80050); Red Sea and East Africa to islands in the western Indian Ocean. Immigrant to Mediterranean via the Suez Canal.
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 14.2 range ? - ? cm
Max length : 30.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 30573); common length : 20.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 30573)
背棘 (总数) : 13 - 14; 背的软条 (总数) : 10; 臀棘: 7; 臀鳍软条: 9; 脊椎骨: 13. Regional variation in color exists. Anterior spines of median fins slender and pungent, posterior spines stout, all venomous including that on the nape. Preopercular angle 87-97 degrees. Anterior nostril with a long, broad flap covering posterior nostril when depressed. Variable cheek scalation. Midline of thorax devoid of scales between the pelvic ridges.
Found in small schools in very shallow water close to the bottom. Prefer hard bottoms of compacted sand with rock or coral debris. Solitary adults and groups of 3 or 4 adults have also been observed. Feed on a wide range of benthic algae. May suddenly stop and erect its fins (dorsal, anal and pelvic) presenting an encircling array of spines to potential predators; these spines are venomous. A food fish that is occasionally poisonous (Ref. 4537). Probably does not adapt well in captivity (Ref. 12382). A thermophilic species (Ref. 120766). Minimum depth from Ref. 9710.
The larvae maintain themselves near the water surface (Ref. 1419). Feeding on phytoplankton and zooplankton begins 3 days after hatching (Ref. 1419).
