Right whales feed on calanoid copepods and other small invertebrates (smaller copepods, krill, pteropods, and larval barnacles), generally by slowly skimming through patches of concentrated prey at or below the surface. Supercohort: Theria It is likely that certain stem toothed mysticetes possessed some form of baleen in the upper jaw. Groups of males are often seen surrounding a female, and mating with multiple males in these groups appears to be common. Their only function is to allow insertion of smooth muscles related to the genital apparatus, and noticeably the m. ischiocavernosus (in both sexes) and the m. retractor penis (only in males). This was the first species of whale to be commercially hunted, starting in the 11th century with a Basque fishery in the Bay of Biscay.

Some individuals may appear mottled, which is caused by uneven sloughing of patches of skin. Loose sutures between the feeding apparatus and cranium account for the common loss of the rostrum in fossil mysticetes; perhaps, such sutures function in skull kinesis during filter feeding. The eyes are located just above the corners of the mouth, and the blowholes are located at the highest point of the rear part of the head; they point slightly to the sides.
