जीवविज्ञान     शब्द संग्रह (उदाहरणार्थ epibenthic)

Prefers warm, well-oxygenated water, mainly larger rivers and lakes; all but the largest form roving schools of like-sized fish; aptly described as fierce and voracious; feeds on whatever prey is most abundant but Brycinus, Micralestes, Barbus, and Limnothrissa are favored (Ref. 7248). Useful food fish in some areas (Ref. 4967).
