Description

The yellow bobo is a threadfin (Polynemidae) from the eastern Pacific. The species has a streamlined, silvery body with yellowish fins and, below the pectoral fin, a bundle of free, thread-like fin rays dragged over the bottom as feelers. It inhabits coastal waters and estuaries on sand and mud bottoms, also along sandy beaches. With its feelers it detects prey in turbid water: small crustaceans, worms and small fishes. It is a valued food fish. The species is harmless to humans.
