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 prey of 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
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.
Drone videos of gray whales off Oregon have revealed new details about how the marine mammals find food. The findings were described in studies this summer. Drone video of gray whales offers new ...
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.
Blue whales appear to avoid directly competing with other baleen whales. [81] [82] [83] Different whale species select different feeding spaces and times as well as different prey species. [73] [84] [85] In the Southern Ocean, baleen whales appear to feed on Antarctic krill of different sizes, which may lessen competition between them. [86]
Baleen whales can have streamlined or large bodies, depending on the feeding behavior, and two limbs that are modified into flippers. The fin whale is the fastest baleen whale, recorded swimming at 10 m/s (36 km/h; 22 mph). Baleen whales use their baleen plates to filter out food from the water by either lunge-feeding or skim-feeding
