简单描述
型态特徵 | 形态测量图
Gymnotus pantanal differs from other members of the G. pantherinus species-
group (except G. anguillaris) in possessing a color pattern composed of thin obliquely oriented pale pigment bands (about one third the width of the dark bands) with wavy margins restricted to the ventral portion of the body (rarely extending above the lateral line) on
the anterior half of the body. Gymnotus pantanal further differs from other members of the G. pantherinus species-group in possessing a wider head (72–77 vs. 52–69% head length). Gymnotus pantanal further differs from G. anguillaris in possessing more narrowly set eyes (37–41 vs. 43–56% head length), a deeper head (66–74 vs. 60–65% head length), larger branchial openings (38–43 vs. 29–36% head length), longer pectoral fins (51–56 vs.
42–50% head length), more pectoral-fin rays (mode 17 vs. 16), and fewer pored posterior
lateral-line scales (to first ventral ramus: 47–58 vs. 58–62; total: 102–114 vs. 124–130).
Gymnotus pantanal 与其他 G. pantherinus 种的成员不同-
群 (除了 G. anguillaris 以外) 在用波浪状的边缘持有彩色斑纹组成物为细的斜向灰白的有颜色条纹 (大约三分之一深色条纹的宽度) 方面局限于身体 (很少地延伸在侧线上面) 的腹部分了
身体前半部。 Gymnotus pantanal 进一步在持有一个较宽的头部方面与其他 G. pantherinus 种群的成员不同。 (72-77 vs.52-69% 頭長) Gymnotus pantanal 進一步有別於 G. anguillaris 在更狹窄持有方面豎立眼 (37-41 vs.43-56% 頭長) ，一個較深的頭部 (66-74 vs.60-65% 頭長) ，較大的鰓裂 (38-43 vs.29-36% 頭長) ，較長的胸鰭 (51-56 vs.
42-50% 頭長), 更多的胸鰭鰭條 (模態 17 vs.16), 與較少數有孔的在後部了
側線鱗片 (對第一腹面分支: 47-58 vs.58-62; 總數: 102-114 vs.124-130).
Facultative air-breathing in the genus (Ref. 126274); Found in rooted grasses and floating macrophytes in small creeks and along the banks of larger backwater rivers (Ref. 54472). Occurs syntopically with Gymnotus inaequilabiatus and G. sylvius (Ref. 54472).
发现于在小溪中的生根草与漂浮的大型植物而且沿着较大的回流水河的岸了。 (参考文献 54472) 生存与 糙唇裸背电鳗〔Gymnotus inaequilabiatus〕 与 G. sylvius 有邻接关系.(参考文献 54472)
