Plankton are a diverse group of marine organisms, which are carried by tides and currents. Most are microscopic, but there are some larger plankton, such as some types of jellyfish. Phytoplankton are ...

Even its ancestry is an enigma. Phylogenetic trees place Sukunaarchaeum as a “deep-branching” member of the domain Archaea—one of life’s three great domains that includes extremophiles and gave rise ...

The ocean is teeming with microscopic plants and animals known collectively as plankton. Each individual organism is tiny, yet, taken as a whole, this free- floating community delivers important ...

In the vast and often unseen world of microscopic life, a recent discovery may force scientists to rethink what it means to be alive. Nestled inside a tiny plankton cell, researchers found a ...

They drift aimlessly at sea, soaking up sunlight from the sky and nutrients from the deep. Often invisible to the naked eye, these tiny invertebrates form the hidden backbone of ocean ecosystems.

Ecologist Paula Pappalardo hones strategies for identifying these critical ocean organisms Madison Goldberg Plankton such as hyperiids, a group of crustaceans known for their complex eyes, make up ...

An up-close portrait of a corkscrew-shaped plankton, a peek into a painted turtle's eye and a magnified view of a marine worm are among this year's winners of a photography contest that honors all ...

Only 170 million years ago, new plankton evolved. Their demand for carbon and calcium permanently transformed the seas as homes for life. Evolution is usually depicted as a consequence of the ...

Ocean warming caused by anthropogenic greenhouse gas emissions will prompt many species of marine plankton to seek out new habitats, in some cases as a matter of survival. Researchers expect many ...
