Plankton is the term applied to any small drifting organisms that float in the sea (Greek planktos = wanderer or drifter). By definition, organisms ...
A planktivore is an aquatic organism that feeds on planktonic food, including zooplankton and phytoplankton. [1] [2] Planktivorous organisms encompass a range of some of the planet's smallest to largest multicellular animals in both the present day and in the past billion years; basking sharks and copepods are just two examples of giant and microscopic organisms that feed upon plankton.
General characteristics of a large marine ecosystem (Gulf of Alaska).

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]
A humpback whale (Megaptera novaeangliae) A leopard seal (Hydrurga leptonyx). Marine mammals are mammals that rely on marine (saltwater) ecosystems for their existence. They include animals such as cetaceans (whales, dolphins and porpoises), pinnipeds (seals, sea lions and walruses), sirenians (manatees and dugongs), sea otters and polar bears.
The center’s right whale ecology team was looking for North Atlantic right whales during a trip on Monday. In January, they had spotted the first of the rare cetaceans for the year in the bay.
Rorquals (/ ˈ r ɔːr k w əl z /) are the largest group of baleen whales, comprising the family Balaenopteridae, which contains nine extant species in two genera.They include the largest known animal that has ever lived, the blue whale, which can reach 180 tonnes (200 short tons), and the fin whale, which reaches 120 tonnes (130 short tons); even the smallest of the group, the northern minke ...
