Longfin Batfish
Platax teira
Longfin Batfish (Platax teira) is a large, deep-bodied marine fish common on reefs, lagoons, and sheltered coastal waters across the Indo-Pacific. Juveniles often school in shallow protected areas, while adults are usually solitary or in small groups near reefs and wrecks.

Identification points
- Very tall, laterally compressed body with an extended dorsal and anal fin outline
- Long, falcate trailing fin lobes on juveniles and subadults
- Silvery to brown body often with dark vertical bars or mottling, especially when young
Habitat
Sheltered coral reefs, lagoons, estuaries, harbors, and wrecks; juveniles favor shallow mangrove-fringed or protected inshore waters, adults range deeper along reef slopes and drop-offs.
Bait notes
Small strips of squid, shrimp, clam, and cut fish work better than bulky baits; small soft plastics and flies that imitate plankton or shrimp can take juveniles. They are not a major game fish in most areas.
Behavior
Omnivorous and opportunistic, feeding on small crustaceans, zooplankton, algae, and benthic invertebrates. Juveniles are schooling and very laterally compressed; adults are more solitary and may follow structure or current edges.
Caution
Spines and fins can be sharp, so handle carefully. Local take may be restricted in some reef areas; check regional regulations before keeping fish.
Fishing notes
Fish around reefs, pilings, wrecks, and protected shorelines with light to medium tackle and small hooks. Present baits near midwater or just above structure; slow retrieves and subtle drifts often outperform aggressive techniques.
