The killer whales regularly demonstrate their competence by chasing seals up shelving gravel beaches, up to the edge of the water. The pursuing whales are occasionally partially thrust out of the sea by a combination of their own impetus and retreating water, and have to wait for the next wave to re-float them and carry them back to sea.

For the Iñupiat, subsistence hunting and fishing are important and viable economic strategies, which provide food and raw materials for the whole group. [1] When hunters bring whales back to the community, about 65–70 people drag the whale onto the ice, where they work all day to harvest the meat.
People from Norway started hunting whales around 4,000 years ago, and people from Japan began hunting whales in the Pacific at least as early as that. [124] Whales are typically hunted for their meat and blubber by aboriginal groups; they used baleen for baskets or roofing, and made tools and masks out of bones. [124]
In the drone video, they observed that younger, smaller whales often swam sideways or facing forward, opening and closing their mouths to find and take in food. Older, bigger whales, meanwhile ...
The whale then pushes the water out, and animals such as krill are filtered by the baleen and remain as a food source for the whale. Baleen is similar to bristles and consists of keratin, the same substance found in human fingernails, skin and hair. Baleen is a skin derivative. Some whales, such as the bowhead whale, have
Baleen whales get the water they need from their food, and their kidneys excrete excess salt. [61]: 101 The lunge-feeders are the rorquals. To feed, lunge-feeders expand the volume of their jaw to a volume bigger than the original volume of the whale itself.
"Those whales, that have spent their entire lives in captivity, their closest relationship is with humans. They are the ones who have provided them with food, care, activities and social relations.
Whales transport more nitrogen through their feces in certain regions than all the rivers combined, enriching both primary and secondary productivity. Additionally, the iron -rich feces of krill-eating whales encourage phytoplankton growth, benefiting the marine food chain and sequestering carbon dioxide for extended periods.
