生物学特性     字汇 (例如 epibenthic)

Inhabits fringing vegetation of rivers and lakes, feeding on zooplankton, beetles and other insects (Ref. 28714). Often reported in West Africa under name of M. acutidens. Affinities: most similar to M. acutidens, from which it differs in the presence of conical, monocuspid (vs multicuspid) inner dentary teeth, inner premaxillary and outer dentary with fewer cusps, and a slightly more slender body (Ref. 80290).

栖息于河川与湖泊的岸边植丛, 捕食浮游动物, 甲虫与其他的昆虫.(参考文献 28714) 时常在 M. acutidens 的名称下面的非洲西部报告。 附注所有的种尚比西河的典型与刚果有一个 2个颚的 polycuspid 齿的第二列与锥形类似苏丹流域的。
