A bottlenose dolphin is seen "bow riding," or swimming just in front of a humpback whale, potentially getting a boost from the wave created by the larger mammal.

Whales and Dolphins Interact More Often Than Scientists Thought, Engaging in Mutual Play, Study Suggests

Researchers analyzed nearly 200 videos and photographs documenting interactions between the various kinds of cetaceans

Only a small fraction of the world’s fisheries—roughly 2 percent—are currently monitored by observers, meaning the vast majority of fishing activity, including the bycatch of protected species, happens without oversight.

Could Artificial Intelligence Make It Easier and Safer to Monitor Fisheries?

New A.I. analysis systems aim to count fish and identify species, streamlining the time-intensive process of recording commercial fishing activity

The new species lives in the tropical and subtropical waters of the Atlantic, from the eastern United States down to Brazil.

Small, Secretive Gecko Rediscovered in the Galápagos After Scientists Eliminate Invasive Rats

Researchers thought leaf-toed geckos were locally extinct on Rábida Island, so they were thrilled to find several of the lizards alive and well during 2019 and 2021 expeditions

 The scientists found R. wellingtoni in two different color combinations, black-purple and red-black.

Scientists Just Found a Coral Species They Thought Had Gone Extinct, Marking the First Record of It in 24 Years

After the 1982-1983 El Niño warming event, the coral endemic to the Galápagos Islands experienced sharp population declines and was rarely observed during surveys

The destroyer was commissioned in 1942 and used in the Guadalcanal campaign.

Scientists Shed Light on the Mysterious ‘Cold Blob’ in the North Atlantic Amid a Search for Its Cause

In two recent studies, researchers suggest a weakening ocean current system is to blame for a persistent cold spot in the Atlantic Ocean, though other factors may also be at play

Orcas are highly social creatures that often share prey with each other. Now, new research suggests they're extending this behavior to humans.

Orcas Appear to Be Sharing Their Prey With Humans—but What Does It Mean?

Researchers documented 34 instances of purported prey-sharing behavior, which suggests orcas may be altruistic and capable of recognizing sentience in another species
