Africa: Guinea (Ref. 28587, 57226) to the Congo River estuary, Democratic Republic of the Congo (Ref. 86940). Records of a specimen from marine waters off Punta Durnford are questionable.

Morphology | Morphometrics
soft rays: 2 - 3. Diagnosis: extremely elongate; tubular snout, which is moderately elongate, ratio head length/snouth length 1.9-2.1; tail longer than head and trunk; ratio SL/head length 6.7-7.5; body encased by bony plates or rings; 13-14 rings before, 32-34 behind, anus; dorsal-fin origin above anal fin, either on last ring of trunk or on first ring of tail; pelvic fins absent; 14-17 pectoral-fin rays; anal fin strongly reduced, with 2 or 3 rays; 9 caudal-fin rays; brood pouch of males on underside of tail (Ref. 57226).
Occurs in coastal rivers and estuaries (Ref. 4127). Has been recorded in waters with a temp. range of 26.0-29.0 °C (Ref. 4959). Lives among algal where it mimics the coloration of the vegetation. Feeds on small prey and organic debris. Ovoviviparous (Ref. 205). The incubation of the eggs takes place in a marsupial pouch found in front of the tail of the males (Ref. 5377).
