Siganidae (Rabbitfishes)
Etymology: Siganus: Latin, siganus = a fish, rabbit fish; by the similarity of the nose (Ref. 45335).
Issue
Cuvier in Guérin-Méneville, circa 1830.
Environment: milieu / climate zone / depth range / distribution range
生态学
海洋 礁区鱼类; 深度上下限 0 - 15 m (Ref. 90102). 热带; 20°N - 29°S, 102°E - 174°W
Western Pacific: scarcely entering the Indo-Malayan area (except eastern Indonesia), north to Palau and Kosrae, south to northwestern Australia and Tonga (Ref. 43045). Replaced by closely related Siganus virgatus from Sulawesi and the Philippines to south India (Ref. 37816).
西太平洋: 几乎不进入印度-马来区域 (除了印度尼西亚东部以外), 北至帛琉与科斯瑞, 南至澳洲西北部与东加.(参考文献 43045) 被接近地取代了讲来自苏拉威西与菲律宾到印度南方部的 Siganus virgatus 。 (参考文献 37816)
大小 / 重量 / 年龄
Maturity: Lm ? range ? - ? cm
Max length : 25.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 48637); common length : 20.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 9813)
背棘 (总数) : 13; 背的软条 (总数) : 10; 臀棘: 7; 臀鳍软条: 9; 脊椎骨: 13. Body blue above, silvery white below; from nape through eye to chin a seal brown band, another from base of 4th-5th dorsal spines to just below of pectoral fin. Spines stout, pungent and venomous. Preopercular 97°-110°. Strong scales cover cheeks. Midline of thorax fully scaled; sometimes a few scales absent from pelvic ridges.
身体蓝色的上方, 下面银白色的; 从后颈经过眼睛到下巴一条海豹褐色条纹, 另外从第四到第五背棘的基底到在胸鳍正下方。 棘矮胖的，尖锐的与有毒的。 前鳃盖骨 97 °-110 °. 强的鳞片覆盖颊。 胸的中线完全覆盖着鳞片; 有时一些鳞片腹鳍脊没有出现。
Inhabits coral-rich areas of lagoons and seaward reefs. Juveniles form schools. Pairs form at 7 cm; but these pairs continue to form loose schools, sometimes with juvenile scarids, to feed in areas being flooded by the tide. At 20 cm, isolated pairs in deep water lagoons or on drop-offs at reef-edges feed on benthic seaweeds (Ref. 9813, 48637). Anterolateral glandular grooves with venom gland (Ref. 57406). Very closely related to the blue-spotted S. virgatus (Valenciennes) and apparently hybridizes at times with it in the Indo-Malayan region (Ref. 2334). Minimum depth reported taken from Ref. 128797.
栖息于舄湖与临海礁石的珊瑚丰富的区域。 稚鱼形成鱼群。 在 7 公分时成对生活; 但是这些对继续形成松散的鱼群,有时有幼年的鹦哥鱼, 在被潮水泛滥的区域中觅食。 在 20 公分，孤立的对在深水舄湖中在礁区边缘或在海峭壁上吃水底的海草.(参考文献 9813,48637) 用毒液腺的前外侧的腺凹槽.(参考文献 57406) 与有蓝色斑点的 S. virgatus(Valenciennes) 亲源非常相近而且显然地在印度-马来区域中偶而以它杂交。 (参考文献 2334)
