The Cubera snapper is an aggressive carnivore with strong canines that allow it to have a varied diet of fish, shrimps and crabs (4) (6). However, it is not a top predator and adults are prey to sharks, barracuda, groupers, moray eels and even other snapper species (6).
The Cubera snapper travels great distances between March and August to off-shore reefs, where large numbers aggregate to spawn. The location and timing of these aggregations, which can contain between 4,000 and 10,000 individuals, appears to be consistent every year and are supposedly cued by a range of environmental factors, including the lunar cycle and water temperature (2).
Within 24 hours of spawning, the eggs hatch into larvae which are then dispersed via water currents; little else is known about the larval stage (6). There is also limited information on young juveniles (7), probably as a result of the difficulty in distinguishing young Cubera snappers from the similar, related grey snapper (Lutjanus griseus) (3).
