生物学     用語集 (例 epibenthic)

Facultative air-breathing (Ref. 126274); Occurs in marginal water-lily and papyrus swamps as well as in marginal weed beds; abundant in high mountain streams and torrents and on the bottom among stones; not found in any situation lower than about 915 m above sea level nor in water of a higher temperature than 18 °C (Ref. 248). In the Rukwa and Malawi drainage they are sometimes found in very cold upland streams (Ref. 78218). These fishes are omnivores, feeding on insect larvae and sometimes also fishes (Ref. 78218).
