The Blob, a long-lasting mass of warm water, sat off the Pacific coast of North America for years, bringing new species to formerly cold waters. What allows some to survive while others fade away?
When conditions are just right in some parts of the Indian Ocean, a type of bacteria will multiply and start to glow. Satellites are helping scientists study these milky seas for the first time.
Warm-blooded fish can swim 1.6 times faster than their cold-blooded relatives.
Ophiojura, discovered living on a seamount deep in the Pacific Ocean, is the last known survivor of a unique group of animals that diverged from its closest relatives way back in the Jurassic period.
Scientists watched in real time as rising ocean heat transformed the sprawling reef. It was a harbinger for ecosystems everywhere as the planet warms.
If octopuses simply started evolving a smarter brain, what stops them from ruling over humans? Why has this not happened already? An expert explains what these cephalopods might be capable of.
Microphones on the seafloor recorded life under the Antarctic ice for two years – inadvertently catching seal trills and chirps that are above the range of human hearing. Could they be for navigation?
There are more viruses in the ocean than stars in the Milky Way – and they’re fundamental to Earth’s biodiversity.
Rather than breathing in and out through the mouth, fish use a one-way system, passing water in one direction over their gills.
It's time to listen to warnings from the people of the Pacific.
Hurricane Harvey destroyed the fishing infrastructure of Aransas Bay and reduced fishing by 80% over the following year. This removed humans from the trophic cascade and whole food webs changed.
Companies are eager to mine the deep ocean for valuable mineral deposits. But scientists are concerned about impacts on sea life, including creatures that haven’t even been discovered yet.
Towns and cities create an orange glow on the horizon at night. It's so widespread that it even disturbs sea creatures.
Too many small yachts and speedboats are simply being abandoned to shed toxins and microplastics into the sea.
The discovery that such a common animal can rapidly produce vast numbers of nanoplastics is particularly worrying.
The extraordinary story of a stingray, its discovery and its uncertain fate in the Yemen war.
Wild dolphins are fast, smart and hard to study, but it is important to understand how human actions affect their health. So we are building a drone to sample hormones from the blowholes of dolphins.
Microscopic ocean phytoplankton feed a “biological pump” that carries carbon from the surface to deep waters. Scientists have found that this process stores much more carbon than previously thought.
Researchers are using a newly developed satellite tag to study previously unknown aspects of tiger shark reproduction. This approach could be used on other difficult-to-study shark species.
The Deepwater Horizon oil disaster catalyzed a decade of research on oil contamination in the Gulf of Mexico, from surface waters to the seabed, with surprising findings.
