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) : 0; 臀鰭軟條: 230 - 320. Distinguished from its congeners endemic to the Amazon and Orinoco basins and the Guyana Shield in having a color pattern of 14-20 oblique, dark, pigment bands with wavy and irregular margins in which the majority of bands are branched ventrally to form inverted Y-shaped patterns (in adults), in which the dark bands are about twice as broad as the pale interbands and in which the bands rarely form X-shaped patterns at midbody. Further differs in having the following unique combination of characters: clear (unpigmented) patch at the caudal end of the anal-fin membrane in specimens 6-23.5 cm; bands never divided to form band pairs (Ref. 55508).
在有一個方面與它的同類區分了亞馬遜河的特有種與奧里諾科河流域與蓋亞那盾甲 14-20 斜角的彩色斑紋, 深色的, 有顏色條紋用波浪狀而不規則的邊緣在那一個多數的條紋腹地被分枝形成反轉 Y 形的圖案 (當成魚時), 在那裡深色條紋是像灰白的 interbands 一樣的寬大約兩倍於與在那一個條紋很少地在身體中央形成 x-形狀的圖案。 進一步不同之處為有下列的獨特組合特徵: 在臀鰭薄膜的尾鰭末端在標本 6-23.5 公分的清澈的 (沒有顏色) 小區塊; 條紋從不分開形成條紋對。 (參考文獻 55508)
Facultative air-breathing in the genus (Ref. 126274); Inhabits mainly isolated swamp pools in the rain forest, which it can reach by moving over-land through moist leaf litter (Ref. 55508). Also occurs in small swamp pools that are never connected to streams and that dry out completely during periods of draught (Ref. 55508). Undertakes aerial respiration by gulping atmospheric air into the hypervascularized posterior chamber of the gas bladder (Ref. 55508). Observed to survive out of water for many hours on a moist substrate (Ref. 55508). Feeds mainly on chironomid larvae, insect nymphs and allochthonous invertebrates that fall from the forest canopy (Ref. 55508).
主要棲息於在雨森林中隔離沼澤水池, 它能被移動達到-登陸過潮溼的腐葉.(參考文獻 55508) 也生活於小的沼澤水池從不那是連接到溪流，而且那在氣流的期間完全地乾掉中.(參考文獻 55508) 進行藉由吞大氣的空氣進入氣鰾的 hypervascularized 後室呼吸空氣.(參考文獻 55508) 觀察存活在一個潮溼的底部上離開水面許多小時.(參考文獻 55508) 主要吃寶刀魚仔魚, 昆蟲的蛹與從森林覆蓋掉下的外來的無脊椎動物。 (參考文獻 55508)
