簡短描述
檢索表 | 型態特徵 | 形態測量圖
Differs from other Kryptolebias and Rivulus species by a combination of characters including low number of lateral line scales, high number of anal rays, short predorsal length and a robust body, and unique mitochondrial DNA gene sequences. Kryptolebias sepia differs further by remarkably strong melanistic pigmentation and the ability to change this coloration into several distinct patterns, lack of obvious sexual dimorphism, strong dichromatism between juveniles and adults, and absence of the Rivulus spot in females and juveniles (Ref. 53862).
有別於其他 Kryptolebias 與包括側線鱗片的低數字，臀鰭鰭條的高數字，短的前背長度與一個結實的身體 , 與獨特的線粒體 DNA 基因序列的一個組合特徵的 Rivulus 種。 Kryptolebias 烏賊 藉著顯著強 melanistic 顏色與能力不同進一步將這一個顏色換成一些明顯的圖案,沒有明顯的性同種二形, 強的二色變異在稚魚與成魚之間, 而且在母魚與稚魚中缺乏 Rivulus 斑點.(參考文獻 53862)
Found only in primary forests with a very dense canopy cover and appears to inhabits only extremely shallow parts of small creeks in hilly areas. Occurs outside the main stream in swampy areas directly adjacent to creeks.
發現只在初期的森林具有一個非常密集的遮蔭表面而且似乎在多丘陵的區域中居住於小溪的只有非常水淺部份中。 直接地在沼澤的區域中在主要的水流之外生存鄰近小溪。
