Kort beskrivning
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 6 - 7; Mjukstrålar i ryggfenan (totalt) : 7 - 9; Taggstrålar i analfenan: 1; Mjukstrålar i analfenan: 7 - 9; Ryggkotor: 25 - 27. Body dusky grey with irregular vertical bars, blotches and small spots, often almost plain grey; first dorsal fin grey, black posteriorly, bright yellow submarginal band present (Ref. 43716). Longitudinal scales 36-46; TRB 13-18; predorsal scales 12-21, small, reaching forward of preopercular margin but not reaching behind eyes; ctenoid scales on side of body separated into patch behind pectoral fin and area from below second dorsal fin origin back to caudal base (Ref. 43716). Caudal fin rounded (Ref. 43716).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Facultative air-breathing in the genus (Ref. 126274); Occurs intertidally on marine shores, typically in beach-rock pools (near fresh water seepages), in brackish pools behind beach dunes, or in sandy mangrove lagoons along beaches or headlands (Ref. 43716, 44894). Primarily a saltwater fish, but very occasionally found in almost entirely freshwater conditions (Ref. 44894).
