Bubble-net feeding is a feeding behavior engaged in by humpback whales [1] and Bryde's whales. [2] It is one of the few surface feeding behaviors that humpback whales are known to engage in. [3] This type of feeding can be done alone or in groups with as many as twenty whales participating at once. [4]
Over half of this biomass is eaten by whales, seals, penguins, seabirds, squid, and fish each year. Most krill species display large daily vertical migrations, providing food for predators near the surface at night and in deeper waters during the day. Krill are fished commercially in the Southern Ocean and in the waters around Japan.

Examples are swordfish, seals and gannets. Apex predators, such as orcas, which can consume seals, and shortfin mako sharks, which can consume swordfish, make up a fifth trophic level. Baleen whales can consume zooplankton and krill directly, leading to a food chain with only three or four trophic levels.
To use baleen, the whale first opens its mouth underwater to take in water. 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 ...
A humpback whale crossed multiple oceans for a massive migration that covered more than 8,000 miles, according to a new study. Humpback whale makes one of the longest migrations ever recorded Skip ...
A humpback whale straining water through its baleen after lunging. Rorquals feed on plankton by a technique called lunge feeding. [24] Lunge feeding could be regarded as a kind of inverted suction feeding, during which a whale takes a huge gulp of water, which is then filtered through the baleen. [24]
