توصيف مختصر
ريخت شناسي | ريخت ستجي بوسيله انداره گيري
شعاع نرم باله پشتي (کل): 11-12; شعاع نرم باله مخرجي: 11 - 13; مهره ها: 36. Distinguished from other species of Hemiodus by its high body (27.1-35.3%, average 32.3% SL vs. 18.8-28.5% in remaining species). Other diagnostic characters include the following: presence of a large lateral dark spot that is equal to, or greater than, the eye diameter (vs. smaller in remaining species except for Hemiodus microlepis); absence of conspicuous lateral stripe or transverse bands; 68-74 scales on lateral line (vs. 94-123 in Hemiodus argenteus, 124-148 in Hemiodus microlepis, 86-99 in Hemiodus orthonops and 77-92 in Hemiodus parnaguae). Differs from Hemiodus unimaculatus (which overlaps in the number of lateral line scales) by having 9-10 scales between the lateral line and the pelvic fin origin (vs. 4-7), which are similar sized above and below lateral line (vs. scales larger bellow the lateral line in Hemiodus unimaculatus) (Ref. 91067).
Found in slow-flowing stretches of the rio Amana and igarapé Porquinho (1.0-2.5 m deep) and in artificial ponds (4.0-5.0 m deep and 40-70 m in diameter) resulting from gold-mining activities. The Rio Amana and its tributaries are characterized by clear water (not stained by humic acids) but turbid due to excess of fine suspended solids (clay) as a result of mining activities along river margins and/or bottom such as dredging (Ref. 91067).
