Krill are also used for human consumption in several countries. They are known as okiami (オキアミ) in Japan and as camarones in Spain and the Philippines. In the Philippines, they are also called alamang and are used to make a salty paste called bagoong. Krill are also the main food for baleen whales, including the blue whale.
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
Humpback whales eat a ton of food every day — literally, one ton or more — and they use their baleen (the hair-like structure pictured here) to consumer their meals. ... (mostly krill) and ...
In 2010, researchers found whales carry nutrients from the depths of the ocean back to the surface using a process they called the whale pump. [29] Whales feed at deeper levels in the ocean where krill is found, but return regularly to the surface to breathe. There whales defecate a liquid rich in nitrogen and iron.
Forage fish are the food that sustains larger predators above them in the ocean food chain. The superabundance they present in their schools make them ideal food sources for top predator fish such as tuna , striped bass , cod , salmon , barracuda and swordfish , as well as sharks , whales , dolphins , porpoises , seals , sea lions , and seabirds .
On average, a bubble blast came 27 seconds after a whale dove for food, and most were observed while the whales were doing headstands. The older and bigger a whale got, the greater the probability ...

Whales feed at deeper levels where krill is found, and their fecal matter, rich in iron, rises to the surface. This action enhances phytoplankton productivity and supports fish populations. Whales, along with krill, form a positive feedback loop, where their populations contribute to the recycling of iron, further boosting phytoplankton growth.
