Ekologi
marina; brackvatten revassocierade; djupintervall 1 - 12 m (Ref. 90102). Tropical; 15°N - 40°S
Indo-Pacific: Mozambique, Kenya, Sri Lanka, Papua New Guinea, Australia, and Micronesia; undoubtedly more widespread.
Size / Vikt / Age
Maturity: Lm ? range ? - ? cm
Max length : 7.9 cm SL hane/ej könsbestämd; (Ref. 1602)
Taggstrålar i ryggfenan (totalt): 7; Mjukstrålar i ryggfenan (totalt): 10-11; Taggstrålar i analfenan 1; Mjukstrålar i analfenan: 9 - 10; Ryggkotor: 26. Pectoral fin rays entire. Predorsal cycloid scale 7-10, ctenoid on trunk. Few spots on nape; a dusky line running from eye dorsal to sensory pore path, ending at or before pectoral fin base; wavy brown lines on the snout. Pelvic and distal part of anal fins darker in males than in females. Appressed anal fin reaching within a distance of 1-2 scales of caudal fin in male, 2-4 scales in female; appressed 2nd dorsal slightly overlapping caudal in male. Some males exhibit 3-4 vertical bars on abdomen and 2-3 horizontal bars in 1st dorsal fin (Ref. 420); longitudinal scale series 30-32; no scales on cheek and opercle; body depth 4.9-6.1 in SL (Ref. 90102).
Occurs in turbid coastal areas near river mouths at less than 1 m to at least 12 m, Ref. 48637.
