生物学特性     字汇 (例如 epibenthic)

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.
