生物学     用語集 (例 epibenthic)

Confined to larger lakes and rivers; possibly a shoaling species; polyphagous with a frugivorous tendency; stomach contents examined showed the presence of sand, mud, benthic vegetable remains, leaves, fruits and insect remains (Ref. 43912). Oviparous, eggs are unguarded (Ref. 205). Probably of economic importance locally for fishermen of Lake Tumba; maximum reported TL 280mm (Ref. 43912).
