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) : 9 - 10; 臀棘: 0; 臀鰭軟條: 8 - 9. Distinguished from all Atlantic Canthigaster species (except C. supramacula) by the absence of longitudinal dark stripes on the side of the body or caudal peduncle. Distinguished from C. supramacula by the absence of a conspicuous dark spot on the dorsum (Ref. 43205).
Body shape (shape guide): short and / or deep.
與所有的大西洋的 Canthigaster 種 (除了 C. supramacula 以外) 區分了藉由缺少縱向的深色斑紋在身體或尾柄側邊上。 在背面上與 C. supramacula 區分了藉由缺少一個顯著的深色斑點。 (參考文獻 43205)
Occurs in tide pools and to depths of up to 45 m (Ref. 43205). Also found in rocky areas to at least 50 m depth; adults often in pairs (Ref. 86997).
