Largest of the sei whales. As the larger rorquals became scarce in recent decades, hunting pressure on sei, Bryde’s, and minke whales increased, largely in the Antarctic. Although heavily depleted, sei whales have recovered somewhat more successfully from hunting than other large baleen whales (Ref. 1394). Generally found in coastal, shelf and oceanic waters (Ref. 122680). Feeds at the shelf break and seaward throughout the summer (Ref. 96832). Restricted to mid-latitude temperate zones (Ref. 1394). Uses both skimming and gulping as feeding strategies (Ref. 122680). Skims copepods and other small prey types (Ref. 1394); also feeds on squids (Ref. 122680), euphausiids and a variety of fish including saury and whiting. Also a "swallower." Zooplankton concentrations influence where the whales feed. Migratory (Ref. 96832). Commonly in groups of 2 to 5 individuals (Ref. 801).
