Description

The striped threadfin is a threadfin of the family Polynemidae from the Indo-Pacific. The species grows to about 45 cm and has a streamlined, silvery body with fine dark longitudinal lines along the scale rows and free, thread-like lower pectoral rays. With these sensitive 'feelers' it probes muddy bottoms of the continental shelf, coastal waters and estuaries for hidden prey. As a bottom searcher it feeds on shrimps, small fishes, worms and crustaceans. The striped threadfin is a valued food fish and is sometimes farmed. It is harmless to humans.
