This year’s third-place winner of the 2022 Nikon Small World in Motion competition features sea anemone cells.

Mahi-mahi were more likely to be eaten and less likely to spawn after being exposed to sublethal concentrations of oil, raising concerns about the risks oceanic drilling pose to life in the ocean.

With their laboratories prepared as well as possible for what’s now a Category 3 hurricane, all scientists in Florida can do now is wait.

He was known for his research on iron’s role in phytoplankton biomass.

Bottlenose dolphins can recall trivial details of a prior event to later solve a novel task, a study finds, suggesting these mammals are capable of episodic memory.

The researchers who constructed the first reference genome for this critically endangered mollusk say it will assist restoration efforts.

A study yields insights into how predator-prey dynamics may shift with climate change, but many questions remain.

The first high-quality genome for a marine isopod may shed light on how this group of crustaceans adapted to the deep, dark depths of the ocean.

The roar of nearby boat engines alters how fish care for and protect their young, resulting in fewer successful nests and smaller offspring, a study finds.

Researchers observe that dolphins in a pod in the Red Sea regularly rub against certain corals and sponges, perhaps to sooth their skin by prompting the invertebrates to release mucus that contains antimicrobial compounds.

Two glands increase steroid production after female California two-spot octopuses mate, a study finds. Those hormones may be responsible for the animals’ self-destructive behavior.

Once thought to be silent, fish turn out to produce a range of vocalizations—so polluting the oceans with noise could pose a danger to them.

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.

Edward Ricketts built his laboratory just onshore from the swirling tidepools of Monterey Bay, California, an ideal backdrop against which he developed a new system for studying the ecology of any given habitat.

The size and complexity of cephalopod brain structures differ depending on the habitats the creatures occupy, a study finds.

His work revealed that sharks use an electromagnetic sense to navigate and detect prey.

Avoidance of predation is a driving force behind the daily movements of marine creatures across the food web, a study concludes.

Sea otters are born with a supercharged metabolism that helps them stay warm in chilly waters.

The first evidence of biologically produced elemental carbon inspires more questions than answers.
