وصف مختصر
مفاتيح التعريف | الوصف الخارجي | قياسات المظهر الخارجي
أشعه شرجية لينه: 174 - 197. Brachyhypopomus benjamini is distinguished from other species of the genus Brachyhypopomus by the absence of scales in middorsal region of anterior third of body (vs. presence in all congeners except B. provenzanoi) and by having speckled dorsal surface of body with small brown chromatophores on light brown background (vs. irregular pattern of distinct dark blotches on depigmented tan-colored background in B. provenzanoi).
Body shape (shape guide): elongated.
Facultative air-breathing in the genus (Ref. 126274); Inhabits small low-conductivity blackwater terra firme rainforest streams. Found in and around submerged debris and leaf litter, and in root mats and holes along the stream banks. Feeds on small aquatic invertebrates in the type locality. Occurs sympatrically and syntopically with Brachyhypopomus beebei, B. brevirostris, B. sullivani, B. verdii, and B. walteri. Spawns during the rainy season, approximately December-April, in the area of the type locality (Ref. 116763).
