Common names from other countries
Actinopterygii (ray-finned fishes) > Stephanoberyciformes
(Pricklefishes, bigscales and gibberfishes) > Melamphaidae
(Bigscale fishes or ridgeheads)
Etymology: Melamphaes: Greek, melan, -anos = black + Greek, amphi = both side (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; depth range 0 - 800 m (Ref. 36655), usually 150 - 200 m (Ref. 6747). Deep-water; 40°N - 40°S (Ref. 117121)
Indo-Pacific and Atlantic: in tropical and subtropical waters. Southeast Pacific: Chile (Ref. 9068). South China Sea (Ref.74511).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 2 - 2.9 cm
Max length : 2.9 cm SL male/unsexed; (Ref. 4241)
Adults found mainly below 150-200 m (Ref. 6747). Larvae and juveniles primarily found in depths as shallow as 35-40 m (Ref. 36655). Oviparous, with planktonic eggs and larvae (Ref. 36655). Collections were done mainly by using nonclosing nets (Ref. 117121).
