After three lean years, the ocean off California's coast this summer is suddenly rich in nutrients, and creatures - from microscopic krill to humpback whales - are thriving anew. But whether this ...

Krill, the small shrimp-like crustacean and a primary link in the marine food chain, have returned in huge numbers to the Bay Area coast and Farallones National Marine Sanctuary. This is also ...

Although almost invisible as compared with albatrosses, krill form the underpinnings of food chains throughout the polar oceans and beyond. Krill are small crustaceans, approximately two inches long.

Antarctic krill, tiny creatures that are of major importance in marine food chains, are likely to be affected by warming ocean temperatures, researchers say.

Despite their microscopic size, plankton are crucial for marine ecosystems. They act as the base of the entire food chain in oceans and freshwater. Plankton are microscopic living organisms that drift ...

They don't tend to grow much larger than a couple centimeters in length, and they feed on even smaller creatures, taking tiny photosynthetic plankton and moving them up the food chain.

Deep Antarctic waters are teeming with krill – small shrimp-like creatures near the bottom of the food chain – in a discovery which has amazed scientists. The marine invertebrates, which are a ...

Bottom of the food chain Krill are a major protein source for many marine species: they are one of the main species at the bottom of the food chain.

Without them, the food chain would collapse. In the late 1990s, the task of designing a new $1 million aquarium in Kingston, Tasmania, to house Antarctic krill fell to King unexpectedly.

Ms Ericson said the finding was important because krill are a key link in the Antarctic food chain.

A majority of krill fishing companies have announced their commitment to voluntarily stop harvesting the tiny crustaceans from vast areas of the Antarctic Peninsula, including around important ...
