Africa: Guinea (Ref. 28587, 57226, 81680) to the Congo River estuary, Democratic Republic of the Congo (Ref. 81680, 86940). Also reported from coastal Angola (Ref. 120641). Records of a specimen from marine waters off Punta Durnford are questionable.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 26 - 28; Anal spines: 0; Anal soft rays: 2 - 3. Diagnosis: 14-17 (median 16) pectoral fin rays; head length 6.5-7.5 (mean 7.1) times in SL (Ref. 57226, 81680). Snout tubular, moderately elongate (Ref. 57226), ratio head length/snouth length 1.8-2.3 (Ref. 57226, 81680).

Occurs in coastal rivers and estuaries (Ref. 4127). Seems to be mainly a brackish water species, only occasionally entering fresh water (Ref. 81680). Has been recorded in waters with a temperature range of 26.0-29.0 °C (Ref. 4959). Lives among algae 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). Dawson (1981) reported over 800 postlarvae in a male of 141 mm SL (Ref. 81680). Maximum reported total length 20.0 cm (Ref. 5377).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00037 (0.00016 - 0.00085), b=3.18 (2.99 - 3.37), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.7 ±0.31 se; based on food items.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Price category (Ref. 80766): Unknown.
