আকৃতি / ওজন / Age
Maturity: Lm ?  range ? - ? cm
Max length : 20.0 cm TL পুরুষ/ লিঙ্গ অনিধর্ারিত ; (Ref. 55763); common length : 18.0 cm SL পুরুষ/ লিঙ্গ অনিধর্ারিত ; (Ref. 188)
পৃষ্ঠীয় কাঁটা (মোট ) : 0; পৃষ্ঠীয় নরম পাখনা দন্ড (মোট ) : 13 - 21; পায়ূ কাঁটা : 0; পায়ূর নরম পাখনা্তুন্ড: 12 - 23. The filamentous last dorsal fin rays distinguish it from any other eastern Pacific genus. Separated from other eastern Pacific Opisthonema by having only 25 to 36 lower gill rakers in fishes over 14 cm standard length.
Forms schools. Apparently the least abundant of the eastern Pacific species of Opisthonema. Feeds on crustaceans and pteropods. Caught along with the other species of the genera.
