The albacore is a powerful, hard-hitting predator that forms mixed schools with skipjack tuna, yellowfin tuna, and bluefin tuna, sometimes around floating objects like sargassum weeds.
Schools of albacore are highly migratory within bodies of water and segregated by maturity, with older fish tending to form more compact groups.
Of those caught by humans, immature albacore have a 1:1 sex ratio while older albacore are mostly male.
In the Atlantic Ocean, older fish are found in cooler waters.
The opposite is true for the Pacific Ocean, where fish are found more abundantly along thermal discontinuities.
Depth range also varies by location: Atlantic fish dive as deep as 600 m (2,000 ft) where Pacific fish reach only 380 m (1,250 ft) in depth.
In the northeast Atlantic, feeding migrations to productive areas occur during the summer.
Due to climate changes over the last 40 years, the timing and spatial distribution of the albacore have also changed.

Albacore show a broad range of behavioral differences by region.
In Baja California, albacore make frequent dives to depths exceeding 200 m (660 ft) during the day and stay near the surface at night, while off the coast of Washington and Oregon they stay near the surface the entire day.
Albacore never really rest; their need for oxygen means they must always be on the move.
