This long-lived fish has two distinct stages in its life history. Juvenile wreckfish inhabit the open ocean, where they feed on bony fishes, particularly Trachurus species (jack mackerels) (1). They live for more than two years at the sea surface before settling on the ocean bottom at great depths (4) (5).
Adult fish continue to feed on fish, but also consume squid found in their deep water habitat (1). During spawning, which takes place between late July and early October, wreckfish come together in aggregations and females release their eggs into the deep ocean water (4). Being a multiple spawner, wreckfish release multiple batches of eggs during the spawning season (4). The oldest known wreckfish was a male, found to be 81 years old; the oldest known female was 64 years old (1).
