Eastern North Pacific population – Whales in this region mostly feed off California from summer to fall and then Oregon, Washington State, the Alaska Gyre and Aleutian Islands later in the fall. During winter and spring, blue whales migrate south to the waters of Mexico, mostly the Gulf of California, and the Costa Rica Dome, where they both feed and breed. [24] Perrin, W. F.; Donovan, G. P.

Cambridge, UK: International Whaling Commission.How Pakicetus' descendants evolved into whales is one of the most intriguing evolutionary journeys known to science. What did the first whales look like? There are two types of whales: toothed and baleen. Toothed whales, as the name suggests, have teeth, which are used to hunt and eat squid, fish, and seals. Toothed whales include sperm whales, as well as dolphins, porpoises, and orcas, among others. The narwhal’s “horn” is actually one long tooth protruding through its lip. Today, the closest living relatives of cetaceans are the hippopotamuses; these share a semi-aquatic ancestor that branched off from other artiodactyls some 60 mya. [11] Around 40 mya, a common ancestor between the two branched off into cetacea and anthracotheres; nearly all anthracotheres became extinct at the end of the Pleistocene 2.5 mya, eventually leaving only one surviving lineage– the hippopotamus.

Although whales are expert swimmers and perfectly adapted to life underwater, these marine mammals once walked on four legs. Lydersen, Christian; Weslawski, Jan Marcin; Øritsland, Nils Are (1991). "Stomach content analysis of minke whales Balaenoptera acutorostrata from the Lofoten and Vesterålen areas, Norway". Ecography. 1 (3): 219–222. doi: 10.1111/j.1600-0587.1991.tb00655.x. Baleen whales have no teeth; instead, they have plates of baleen, fringe-like structures that enable them to expel the huge mouthfuls of water they take in while retaining the krill and plankton they feed on. Because their heads are enormous—making up as much as 40% of their total body mass—and they have throat pleats that enable them to expand their mouths, they are able to take huge quantities of water into their mouth at a time. Baleen whales also have a well-developed sense of smell.a b Paul, Gregory S.; Larramendi, Asier (11 April 2023).

As with humans, the whale mode of reproduction typically produces but one offspring approximately once each year. While whales have fewer offspring over time than most species, the survival probability for each calf is also greater than for most other species. Female whales are referred to as "cows." Female cows assume full responsibility for the care and training of their young. Male whales, referred to as "bulls," typically play no role in the process of calf rearing.

For many, the Natural History Museum is a place that inspires learning, gives purpose and provides hope. People tell us they 'still get shivers walking through the front door', and thank us for inspiring the next generation of scientists. To reverse the damage we've done and protect the future, we need the knowledge that comes from scientific discovery.
