Biology     Glossary (e.g. epibenthic)

The largest whales of the world's oceans. They can be seen from the equator to the pack ice edges in both hemispheres, with most poleward intrusions in both hemispheres in summer. Some are resident, others are migratory. Feeds on krill (Ref. 1394). Feeds at depths less than 100 m (Ref. 1005). From the time faster catcher boats and explosive harpoons made them catchable, blue whales were hunted relentlessly from the late 19th through the mid 20th centuries. As the largest whales, they were the most sought after of the rorquals. Although most populations remain well below pre-exploitation levels, some stocks (such as those that feed off California) have shown encouraging signs of recovery since protection by the International Whaling Commission (IWC) in 1965. At least in the eastern North Atlantic and the eastern North Pacific, numbers appear to be on the rise (Ref. 1394).
