簡単な記述 形態学 | 形態計測学

背面の脊椎 (合計): 0; 背鰭 (合計): 21-33; 肛門の骨 0; 臀鰭: 38 - 51. Diagnosis: head depressed, mouth large and terminal; body elongated (Ref. 13337, 52193). Chin (mental swelling) absent; origin of dorsal fin behind origin of anal fin, nearer caudal fin base than tip of snout; dorsal fin shorter than anal fin; mouth width subequal to snout length: snout long (Ref. 52193). SL/Body depth 4.9-7.5; head 3.4-5.1 times in standard length; snout almost as wide as head; interorbital space wide, head length/interorbital space 2.9-6.8; variation in meristic characteristics due to differences in geographic clines (Ref. 2915).

生物学     用語集 (例 epibenthic)

Juveniles occur in marginal habitats, adults prefer deep quiet water between boulders and below overhangs, away from strong currents; also occurs beneath Salvinia mats and in river estuaries in Lake Kariba; juveniles prey on invertebrates, mainly shrimps and insect larvae; larger individuals feed on small cichlids, minnows and labeos; may live for 8 years or more; breeds in summer during the rainy season; mature females carry 25000 or more eggs (Ref. 7248, 52193). A fractional spawner (Ref. 10606, 10605). Affinities: M. breviceps.
