Etymology: Mauligobius: From Maul, ichthyiologist that studied the fishes from Madeira and Canary Islands + Latin, gobius = gudgeon (Ref. 45335).

Ecologie
marien; brak water demersaal. Tropical
Eastern Atlantic: Nigeria to Equatorial Guinea and offshore islands (Ref. 4343, 79590). Also collected from Banana (Congo River estuary), Democratic Republic of the Congo (Ref. 31982). The lack of reliable data for West African specimens suggest that it might be restricted to the Cape Verde Islands (Ref. 57403, 79590).

Morfologie | Morfometrie
Dorsale stekels (totaal): 7; Dorsale zachte stralen (totaal): 10; Anale stekels 1; Anale zachte stralen: 8 - 9. Diagnosis: anterior nostril with rim process divided into several tentacles (Ref. 39517, 57403, 79590). Scales on lower cheek and operculum; 40-46 ctenoid scales in longitudinal series (including about 4-6 scales on the caudal fin base), and 15-17 in rearward transverse series; 1st dorsal fin: VI; second dorsal fin: I,10; anal fin: I,8-9; pectoral fins: 24-26, outer (dorsal) 9-10 rays short, multifid and free from membrane (Ref. 57403, 79590). Anal fin base shorter than caudal peduncle (Ref. 39517).
Coloration: Preserved specimens: head with dark mottling (Ref. 39517, 57403, 79590). Body dark, with about a dozen small spots along the lateral midline (Ref. 39517, 57403, 79590), darker in color than the background pigmentation (Ref. 57403), but lacking vertical dark bars (Ref. 39517). 1st and 2nd dorsal fins with 2-3 oblique rows of small white spots; pelvic fins/disc paler than other fins (Ref. 39517, 57403, 79590). In life: body chestnut-brown , with dorsal, caudal and pectoral fins spotted with brown; anal and pelvic fins blackish (Ref. 57403, 79590).
Occurs inshore (Ref. 4343). Although possibly entering estuaries, this species is more likely a benthic inhabitant (Ref. 57403, 79590) of marine intertidal zones (Ref. 27000, 57403, 79590). Collected in shallow water among large lava-pebbles under strong wave action, and smaller examples came from a boundary area between rocks and sand at 2-4m depth (Ref. 39517). Maximum total length reported 8.7 cm (Ref. 57403).

Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.02 (2.84 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trofisch niveau (Ref.

Weerstandsvermogen (Ref.
