Length at first maturity / Size / Peso / Age
Maturity: Lm 8.2 range ? - ? cm
Max length : 15.0 cm TL maschio/sesso non determinato; (Ref. 57403)
Spine dorsali (totale) : 7; Raggi dorsali molli (totale) : 8 - 9; Spine anali: 1; Raggi anali molli: 7 - 9. Diagnosis: body with 3 broad, oblique, dark cross bars; numerous pale striae along sides, corresponding to the center of each longitudinal scale row; head and pectoral-fin bases with white spots and mottling; predorsal scales extend well anterior to level of preoperculum, and anterior margin of scaled area appears convex in dorsal view (Ref. 57403, 79590). 4-5 outer/upper pectoral-fin rays free (Ref. 57403, 79590), hence its name "Frillfin goby" (Ref. 26938). Body shape is terete, slightly depressed; eyes situated dorso-laterally; reduced swim bladders (Ref. 92840).
A resident intertidal species with homing behavior (Ref. 32612). Lives benthically over sandy and muddy substrates (Ref. 79590). Mainly found in pools (Ref. 4343). Abundant in rocky tide pools and along water's edge (Ref. 7251) in lagoons, creeks, estuaries (Ref. 5299, 57403, 79590) and (mangrove) swamps (Ref. 57403, 79590). Occasionally found in fresh waters (Ref. 57403, 79590), with salinity range of 0.0-38.8 ppt (Ref. 97140). Maximum standard length reported 113 mm (= 145 mm TL)(Ref. 79590).
