Eyes protruding and close together with lower eyelid fold; snout deep; mouth horizontal. Two separate dorsal fins, the first high, with 11 flexible spines, the second lower, its base longer than the distance from end to caudal fin origin; pectoral fins with a long muscular lobe; pelvic fins united across bases; caudal fin with lower rays short, and stout.

Africa: Senegal to Angola (Ref. 7390), including most offshore islands - Macias Nguema, SÃ£o TomÃ©, and Principe islands (Ref. 10814). Western Central Pacific: Guam (Ref. 35720).
Amphibious air-breather (Ref. 31184) that skips or walks on sand or mud in search of food; that is, on exposed intertidal mud flats of estuarine mangrove swamps. Adult feed chiefly on arthropods (crabs, insects, etc.) of the mud surface. Also included in the diet is the white mangrove, Avicennia nitida (Ref. 3026). Spawn in burrows (Ref. 3657).
