The International Whaling Commission (IWC) is the body charged with regulating whaling and addressing the vast number of other threats to whales, dolphins and porpoises in our oceans such as shipping, climate change, and bycatch. Main threats include low numbers of animals combined with extreme longevity and a slow reproductive cycle, complicated in the extreme by climate change, including its direct impact on reducing suitable habitat and indirect consequences such as increased human activities in the species range. Along with removing bowhead whales from the population, killer whale predation pressure could influence bowhead whale behavior. These whales live in the cold Arctic and subarctic saltwater water. Bowhead whales are large and stocky animals, with a rounded body and a large head that comprises about a third of the total length. Bowhead whale populations have rebounded after near extinction. In more good news for whales, marine scientists are reporting that bowhead whale populations have rebounded to near pre-commercial whaling numbers in US waters.
