Etymology: Phractolaemus: Greek, phraktos = fence + Greek, laimos = throttle (Ref. 45335); ansorgii: Named for the presence of 1-3 spines on the scales of the lateral line on the caudal peduncle, and on the 2 scale rows above and below the lateral line series (Ref. 93266).

Short description Μορφολογία | Μορφομετρία

Ραχιαίες άκανθες (συνολικά): 0; Μαλακές ραχιαίες ακτίνες (συνολικά): 6; Εδρικές άκανθες 0; Μαλακές εδρικές ακτίνες: 6; Σπόνδυλοι: 34 - 38. Diagnosis: head depressed and strongly ossified; anterior nostril elongate, forming an oblique, forward-pointing tube; posterior nostril crescent-shaped, located just behind the narial tube (Ref. 2913, 81277). Mouth small, protrusible (Ref. 245, 31256, 81277), placed at tip of a proboscis and opening upwards between the narial tubes (Ref. 2913, 81277), on upper surface of snout (Ref. 245, 31256). Narrow gill opening, but opercles very well developed, covering also the underside of the head where they overlap (Ref. 2913, 81277, 93183).

Facultative or obligate air-breathing (Ref. 126274); Lives in forest pools and swamps (Ref. 41580). Microphagous (Ref. 4910, 41580, 45483), especially phytophagous (epiphytes), and detritiphagous (Ref. 41580). Swim bladder entirely alveolar, functioning like a lung; this adaptation to aerial breathing allows the fish to survive under poor oxygenation conditions (Ref. 2913, 81277); recorded from nearly deoxygenated lungfish nest in Pool Malebo, Congo DR (Ref. 41585). Gonads, which are largely fused, are situated ventrally, not dorsally, in abdominal cavity (Ref. 41580). Mouth can be projected as a small trunk (Ref. 2913). Eggs transparent, yellow-greenish, 1.5-1.7mm diameter; large females may have several thousands of eggs (Ref. 41580). Particular blood system, with dark coloured and an abundant amouth of blood (Ref. 4910).

Life cycle and mating behavior Γεννητική Ωρίμανση | Αναπαραγωγή | Γεννοβολία | Αβγά | Γονιμότητα | Προνύμφες

Males and females have lateral tubercles on their body which probably aid in maintaining contact during spawning (Ref. 38266).
