沒有尖銳斜的 ethmovomerine 塊石。 下頜平行於一條線從吻尖到尾下的碟。 頭部深度 102% HL); 眼大又垂直的眼直徑 25.5%.(參考文獻 41512)
Occurs in very shallow rocky biotopes, usually at exposed sites. Mostly found in the upper 2 m. Feeds mainly from the water column; on plankton when this is available and on insect larvae and other invertebrates that appear in the open water. Has also been observed feeding from the biocover on the rocks (Ref. 5595).
出現於很淺的岩石生存環境, 通常在裸露的位置。 大部份發現於上面的 2 公尺了。 主要地為食從水中; 在浮游生物上當這是有用的時候與在昆蟲幼生與其他的在開放水域中出現的無脊椎動物上。 已經也在岩石上被觀察攝取食物的從附著生物。 (參考文獻 5595)
