簡単な記述
形態学 | 形態計測学
背面の脊椎 (合計): 4; 背鰭 (合計): 6-8; 肛門の骨 1; 臀鰭: 8 - 10. Fresh specimens transparent, with large eyes showing the only color, black. Males smaller than females, shorter and more slender. Head naked; body covered with deciduous scales. Scales in longitudinal series 23-24; in transverse series 6. Sides and back of head with few dark or black spots.
Adults occur from the shoreline to depths of at least 12 m. Caught with collapsible Y-shaped push-nets (sakag); also aggregated using a device (abung) wherein the fish comes to rest upon palm leaves and are then harvested using triangular nets (sarap). Sinarapan is a delicacy and of great economic importance to the communities around the lakes. Listed in the Guinness Book of World Records as 'smallest food fish' (Ref. 6472).
Life cycle and mating behavior

Males sometimes mature below 1 cm; females a little over 1.1 cm. The eggs are pelagic. Upon hatching, the young swims at the surface for a short while, then settles at the bottom.
