生物学特性     字汇 (例如 epibenthic)

Epipelagic, usually oceanic, but seasonally coming close to shore (Ref. 168). Tolerates ample temperature intervals (Ref. 168). Forms schools by size, sometimes with other scombrids (Ref. 168). Migrates between June and September in a northward direction along the coast of Baja California, Mexico and California (Ref. 168).
