“Humpback whales eat small fish and krill, NOT seals. While they have very large mouths, their throats are roughly the size of a grapefruit, so they can't swallow something as large as a seal ...
The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton.
Bubble-net feeding is a cooperative feeding method used by groups of humpback whales. This behavior is not instinctual, it is learned; not every population of humpbacks knows how to bubble net feed. [4] Humpback whales use vocalizations to coordinate and efficiently execute the bubble net so they all can feed. [4]
Additionally, the iron-rich feces of krill-eating whales encourage phytoplankton growth, benefiting the marine food chain and sequestering carbon dioxide for extended periods. The Southern Ocean , rich in nutrients but iron-deficient, experiences increased phytoplankton blooms due to whale feces, acting as a significant carbon sink .
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
Pod groups also hunt, often with other species. Many species of dolphins accompany large tunas on hunting expeditions, following large schools of fish. The orca hunts in pods and targets belugas and even larger whales. Humpback whales, among others, form in collaboration bubble carpets to herd krill or plankton into bait balls before lunging at ...
