背棘 (总数) : 1; 背的软条 (总数) : 5; 臀鳍软条: 10 - 11. The body is a little elongated, without scales, with one lateral range of bony plaque. The head is large and flattened. Mouth terminal, and has three pairs of barbels. Eyes are small (Ref. 35381).
身体稍微瘦长, 没有鳞片, 有一骨板的侧面范围。 头部是大而平的。 口端位, 而且有三对触须。 眼很小。 (参考文献 35381)
Abundant in calm waters of swamps and mangroves (Ref. 27188). Omnivorous, feeds mainly on organic wastes. Searches for food by digging in the sediment. Active at night, lies hidden in the underwater roots and stocks during the day. Every basic unit of the sound they emit when they move their pectoral spine lasts 100-200 milliseconds with a frequency of 170-250 Hertz (Ref. 35381). Maximum length reported to reach 20 cm TL (Ref. 35381).
丰富的在沼泽与红树林的平静水域中.(参考文献 27188) 杂食性,主要捕食有机的废物。 藉由开始吃沉淀物搜寻食物。 活跃的在晚上, 躺卧在在水中的根与分枝藏在白天期间。 当他们移动的时候，他们发出的每一基本的单位声音他们的胸棘持续 100-200 毫秒频率为 170-250 赫兹.(参考文献 35381) 最大的长度报告达到 20 公分TL 。 (参考文献 35381)
