Longnose Trevally

Interesting Info

• The Longnose Trevally (Carangoides chrysophrys) is an elegant, silvery predator named for its distinctive pointed snout — giving it a streamlined, dart-like profile built for speed.
• Its name literally means “golden eyebrow,” from the Greek chrysos (gold) and ophrys (brow) — a nod to the faint golden streak that often gleams across its upper head and flanks.
• Adults are bright silver with bluish-green tones on the back and small orange or golden spots scattered across the upper body. The fins are often tinged yellow, especially the tail and lower lobe.
• Juveniles are typically found in shallow coastal areas, estuaries, and sandy bays, where they feed on small crustaceans and fish while hiding near reefs or debris for protection.
• As they mature, they move offshore to deeper reef slopes, channels, and open coastal waters, often inhabiting depths between 10–100 m (33–330 ft).
• Longnose Trevallies are quick, alert hunters that feed on small schooling fish, squid, and crustaceans. They use their sharp snout and forward-set eyes to spot prey in open water before striking with precision.
• They are distributed widely through the Indo–Pacific — from the Red Sea and East Africa to southern Japan, New Caledonia, and northern Australia.
• In Australia, they’re found from Shark Bay and the Pilbara region of Western Australia across the tropical north to the Coral Sea and the northern coast of New South Wales.
• Spawning usually occurs in offshore waters during warmer months, with eggs and larvae drifting with ocean currents. Juveniles eventually migrate toward coastal nurseries as they grow.
• They can live for more than 12 years, growing steadily through their life and maturing at around 3–4 years old.
• Divers often describe them as curious but cautious — gliding just beyond reach, turning to inspect their reflection in a camera lens before vanishing into the blue.
