Laboratory experiments find that Toxoplasma, Cryptosporidium, and Giardia can congregate on microplastic beads and fibers, suggesting they might make their way into and around the world’s oceans by hitching rides on tiny bits of trash.

The Scientist spoke with Chapman University’s Yu Zeng about his lab’s finding that the slime-producing cells of the slippery marine fish vary with the creature’s size, which may be an adaptation to thwart different predators.

Projects aimed at collecting big data about the ocean’s tiniest life forms continue to expand our view of the seas.

Blue sharks don't dive as deeply in low-oxygen waters—which become more prevalent as oceans warm—effectively pushing them into areas of high fishing pressure.

Lore has always surrounded argonauts, pelagic octopuses that build shells and travel the seas.

Early investigations of the microbial communities in and around sunken boats reveal that there are patterns to where bacteria settle.

To help create better conservation and management plans, researchers are measuring how marine organisms move between habitats and populations.

Most know Rachel Carson for her work on the dangers of chemical pollutants, but the writer’s earlier prose took readers on a tour of a mysterious underwater world.

Understanding the dinoflagellates that regularly wreak havoc on marine and nearshore ecosystems in the Gulf of Mexico could help researchers mitigate the damage they cause.

A full description of the lifecycle of Karenia brevis could lead to improved monitoring, prediction, and mitigation of the harmful algal blooms it regularly causes.

The storm has already pummeled the Bahamas. Now the US coast prepares.

In the southeastern US, the coming storm disrupts research for many scientists.

Canadian officials are investigating the deaths and implementing regulations to reduce the number of ships that strike the endangered species or snag them in fishing gear.

As sea temperatures rise, mammals and birds may lose their edge over the cold-blooded species they eat, as well as the sharks that hunt them.

Tune in Thursday to see the effects of Hurricane Florence on the Beaufort, NC facility.

A marine flatworm swarms in a circular fashion off the coast of Guernsey.

The adaptation gives better endurance to the Bajau people, known as sea nomads, by increasing spleen size and, in turn, boosting the number of oxygenated red blood cells when diving.  

A group of around 300 whales produced 184 distinct songs over just a few years, according to a new study.
