البيئة: الوسط / المنطقة المناخية / نطاق العمق / نطاق التوزيع البيئة
بحري; مياه مخلوطة قاعية التغذية و المعيشة; مهاجرة بين الياه الملحه و الحلوة لكن ليس للتزاوج (Ref. 51243); نطاق العمق 10 - ? m (Ref. 9811). Tropical; 32°N - 10°S, 48°E - 131°E
الأشواك الظهرية (المجموع) : 0; الأشعة الظهرية الناعمة (المجموع) : 43 - 50; أشعه شرجية لينه: 39 - 42; فقرات: 33. Greyish to brownish dorsally, silvery white on sides. Covered in dark pigment spots.

Upper jaw covered with skin, joined to head, not movable. Jaw teeth minute, in a single series, flattened with 3 cusps (central cusp much larger than those adjacent). Gill membranes joined to belly. Gill slit short, its lower margin slightly below pectoral-fin base. Scales very small, cycloid, and deciduous, barely extending onto fin bases. Naked patch on head and nape with well-defined network of longitudinal sensory canals, patch not extending above pectoral-fin base.
