簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 9 - 10; 臀鰭軟條: 47 - 51. Protocheirodon pi can be distinguished by possessing four synapomorphies proposed for the Cheirodontinae by Malabarba (1998): presence of a pseudotympanum, a hiatus in the body wall musculature lateral to at least a portion of the anterior chamber of the swimbladder; absence of dark humeral spot; possession of pedunculate dentition; and presence of only a single row of regularly arranged premaxillary teeth. It differs from all species of the Cheirodontinae and indeed members of the Characiformes by the unique form of the swimbladder which has a smaller rotund anterior chamber and the posteriorly chamber elaborated into two vertically elongate, side by side, slightly inclined chambers. These modifications resulted to a unique overall pi (?)-shaped structure (Ref. 109753).
Found in marginal areas of rivers and streams, often over sandy substrates and in still backwaters (Ref. 109753).
