Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; brackish; demersal. Tropical
Eastern Atlantic: northern Senegal to the mouth of the Congo (Ref. 4342, 81288). Also reported from Annobon Island (Ref. 5298).
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 8.3 cm TL male/unsexed; (Ref. 81288)
Dorsal spines (total): 12; Dorsal soft rays (total): 14 - 17; Anal spines: 2; Anal soft rays: 16 - 19. Diagnosis: length of supraorbital tentacles varies from approximately 2/3 of eye diameter to 2 times this diameter; longest tentacles occur in male specimens; shape of supraorbital tentacles varies from a single finger-like appendage bearing 2-4 filaments at the rear base to 4 appendages of almost equal length; anterior nostril forms a small tube which bears up to 4 cirri on posterior rim, only 1 in most cases; only one ring of cephalic sensory pores in infraorbital and preopercular series; lateral line does not reach beyond level of 8th-10th spine of dorsal fin; both males and females with a thin crest on head, but crest in females not as high as in males; dorsal fin with 12 spines and 14-17, generally 15-16, soft rays, last spine shorter than soft rays; anal fin with 2 spines and 16-19, generally 17-18, soft rays; caudal fin rounded (Ref. 81288).
Coloration: in alcohol, uniformly clear brown, lower part of head and throat clearer; some individuals with a black spot on membrane between 1st and 3rd dorsal spines; sometimes flanks bearing vertical stripes darker (Ref. 81288).
Euryhaline, entering mouth of large rivers and mangroves, but always in brackish water (Ref. 81288). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114). Maximum SL recorded was 7.0 cm (Ref. 4342).

Estimates based on models
Preferred temperature (Ref.
123201): 25.2 - 28, mean 27.3 °C (based on 164 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00356 - 0.01695), b=3.00 (2.81 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.3 se; based on size and trophs of closest relatives
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).
