Southern bluefin tuna inhabit deep, pelagic oceanic waters
They are found in temperate regions but migrate to warmer, tropical waters for spawning
This species is highly migratory, often covering vast distances across the Atlantic, Indian, and Pacific Oceans
Their diet is diverse, including fish, crustaceans, cephalopods, and other marine organisms
Spawning occurs in warm tropical waters, often at depths where water temperatures range from mild to warm
It is unclear if these tuna spawn annually or at less frequent intervals
Post-spawning, the juveniles remain in nursery areas before joining adult migration patterns
As they mature, their powerful swimming capabilities enable them to undertake extensive migrations across the oceans
