Synbranchidae (Swamp-eels)
Etymology: Monopterus: Greek, monos = one, unique + Greek, pteron = fin (Ref. 45335).
Eponymy: Dr Georges Théodore Louis Bouët (1869–1957) was an army physician, ornithologist and colonial administrator, who served (1896–1900) in Sudan, Madagascar (1900–1904), Ivory Coast, Niger and Dahomey (Benin) (1906–1930). [...] (Ref. 128868), visit book page.

Environment: milieu / climate zone / depth range / distribution range
Écologie
; eau douce démersal. Tropical
Africa: Sierra Leone and Monrovia, Liberia (Ref. 57291, 116049). Reported also from Côte d'Ivoire (Ref. 2828), but its identification is unclear as the specimen has clearly visible eyes (Ref. 116049).
Taille / Poids / Âge
Maturity: Lm ? range ? - ? cm
Max length : 34.0 cm TL mâle / non sexé; (Ref. 57291)
Diagnosis: body naked, slender, elongated and cylindrical, ending in a very tapering point; the caudal part of the body makes less than one third of the total length; no trace of paired or unpaired fins; eye atrophied, deep-set under skin, practically invisible from the outside; conical teeth on jaws and palate; gill opening minute, reduced to a median ovate pore, surrounded with longitudinal skin folds; 4 branchiostegal rays; 3 branchial arches without branchial lamellae; lateral line present; vertebral count: 140-144 abdominal and 39-45 caudal (Ref. 57291).
Colouration: uniformly dark (Ref. 57291).
Obligate air-breathing (Ref. 126274); Contrary to what is suggested by its morphology, this species is not cavernicolous; it burrows in mud, never very far from the sea (Ref. 57291). The male guards and builds nest or burrow (Ref. 205).
