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.
地区的变化颜色存在。 中央的鳍前面棘细长而尖锐又在后部的棘矮胖的, 所有的有毒包括在后颈上的那。 前鳃盖骨角 87-97 度。 当扁平的，前鼻孔有一个长又宽的鳃盖覆盖后鼻孔。 可变的颊鳞片形状。 胸在腹鳍脊之间的没有鳞片的中线。
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.
发现于了在很浅的水域中的小群鱼群接近底部。 偏爱紧密的沙子的坚硬底部有岩石或珊瑚残砾。 独居性的成鱼与群体的 3 或 4 成鱼已经也被观察。 吃宽范围的水底藻类。 可能突然停止而且竖立被呈现环绕的列的它的鳍 (背鳍、臀鳍与腹鳍) 有背骨的对可能的掠食者; 这些棘是有毒的。 一个食用鱼，那是偶然有毒.(参考文献 4537) 可能适应得不好在繁殖场。 (参考文献 12382) 最小深度从参考文献 9710.
