Giant Trevally
Caranx ignobilisAlso known as Ulua, Giant Kingfish, Lowly Trevally, Barrier Trevally
Giant trevallies patrol shallow coral reefs, lagoons, and drop-offs as formidable apex predators of the tropical Indo-Pacific. Renowned for their sheer power, they employ diverse hunting strategies ranging from shadowing foraging sharks to leaping out of the water to snatch fledgling seabirds from the surface. Adults are typically solitary or swim in small packs, gathering in massive aggregations around deep reef promontories to spawn during lunar cycles.
