Krill (Euphausiids) [1] (sg.: krill) are small and exclusively marine crustaceans of the order Euphausiacea, found in all of the world's oceans. [2] The name "krill" comes from the Norwegian word krill, meaning "small fry of fish", [3] which is also often attributed to species of fish.

2024年9月10日 · Human harvesting of krill in the Southern Ocean could threaten the recovery of whale species that were nearly wiped out by industrial whaling in the 20th century, according to a Sept. 10 study in Nature Communications. The tiny, shrimp-like crustaceans known as krill are the essential food source for baleen whales such as blues and humpbacks.

2019年7月3日 · Krill are shrimp-like arthropods that make up a large portion of the zooplankton in many regions of the ocean. Krill are near the base of the oceanic food web feeding on phytoplankton. In turn, enormous swarms of krill feed the largest creatures in the ocean: blue and other baleen whales, sea birds, squid, and fish.

2023年10月19日 · Whales primarily eat krill, which are tiny shrimp-like crustaceans. They are able to eat so many of them because they exist in such large numbers in the ocean. The name ‘whale’ almost immediately conjures up the image of a mammoth sea creature splashing in …

2024年9月11日 · Antarctic krill fishing could threaten the recovery of whale species that were nearly wiped out by industrial whaling, according to a study led by CU Boulder and Stanford University, and published Sept. 10 in the journal Nature Communications.

5 天之前 · Aboard the Allankay, she is helping document the conflict between whales and industrial krill fishing vessels—something scientists know is happening, but have struggled to quantify with scientific precision. “We know that recovering populations of whales are foraging and sharing resources with krill fisheries. We want to move beyond ...

Krill is the near-exclusive food for giant blue whales, and seabirds like auklets and shearwaters. Commercially valuable salmon, rockfish, flatfish, sardines and squid thrive on krill. When abundant, animals migrate thousands of miles to feed on krill. But when absent, the entire marine ecosystem suffers.

2024年10月7日 · Baleen whales filter feed on plankton or krill in the upper reaches of the oceans, diving to depths of up to 300 metres. The researchers identified genes linked to stress response or blood homeostasis linked to the requirements of this diving behaviour.

2024年10月22日 · Researchers at Stanford’s Marine Hopkins Institute found that the Southern Ocean’s krill population, declining thanks to human activity, is insufficient to support today’s recovering whale ...
