簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 0; 背的軟條 (總數) : 22 - 23; 臀棘: 0; 臀鰭軟條: 4 - 5. Anal fin rays divided at base; tail rings 36-38; subdorsal spines 4/0,0,1,1 or 5/0,0,1,1,1; nose ridge slightly raised, without a spine; spine above eyes moderately large, angled back and laterally outward; lateral head spine moderately large and recurved; coronet slightly raised, apex with 5 blunt diverging spines; upper shoulder-ring spine of small to moderate size, situated beside gill openings; central shoulder-ring spine of moderate size and directed laterally outward; superior trunk and tail ridges with broad thorn-like blunt spines, enlarged on some rings, at regular intervals; superior tail ridge with tubercle-like spines of moderate size, angled backward; trunk ridges followed by connecting tail ridges with spines and tubercles becoming gradually smaller posteriorly; lateral line with distinct pores, on trunk rings just above lateral ridge, continuing onto tail to 18th-23rd tail ring, each pore between raised papillae (Ref. 42735).
臀鰭棘條在基底分開; 尾環 36-38; 子背部的棘 4/0,0,1,1 或 5/0,0,1,1,1; 鼻脊些微地升起, 沒有棘; 眼睛上方的棘普通大的, 背面有角的與側面地向外; 側面的頭部棘普通大而後彎的; 冠些微地升起,尖頂 5 鈍的分開棘; 小到中等大小的上面肩環棘, 位於鰓裂旁邊了; 中央的肩環棘中等大小的而且朝向外側; 上方的軀幹與尾部脊有寬的像刺一樣的鈍棘,在一些環上增大了, 在固定的間隔; 上方的尾部脊有像小瘤一樣的棘中等大小的, 後面有角的; 跟隨著連接尾部的軀幹脊脊有在後部地變得逐漸比較小的棘與小瘤; 側線有明顯的孔, 在軀幹環上在延伸到對第 18-第 23個尾環的尾部, 在凸起的乳突之間的每個孔的側面的脊的正上方.(參考文獻 42735)
Adults inhabit shallow algae or weedy reef areas from the intertidal to about 20 m depth (Ref. 42735). Maximum length is based on a straight-line length measurement from upper surface (ignoring spines) of first trunk ring, to tip of tail (Ref. 42735). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).
棲息於水淺的藻類或者雜草叢生的礁區從潮間帶到大約 20 公尺深度.(參考文獻 42735) 最大的長度是以來自第一個軀幹環的上表皮 (忽略棘) 的一個直線長度測量為依據, 對尾尖.(參考文獻 42735) 卵胎生的.(參考文獻 205) 雄魚帶卵在一個孵卵袋是在尾部下面發現.(參考文獻 205)
