Using drones, 17 distinct behaviors of narwhals were captured in the wild. Findings reveal complex behaviors of the Arctic’s iconic whale never seen before. This highly gregarious whale uses its tusk to investigate, manipulate and influence the behavior of a fish, the Arctic char. The study also provides the first evidence of play, specifically exploratory-object play, and the first reports of kleptoparasitism, a “food thief” situation, among narwhals and glaucous gulls.

Austin Gray received a $1.3 million National Science Foundation Faculty Early Career Development Program (CAREER) award to explore the ecological effects of microplastics.

Shark sightings by scuba divers reveal the movements of marine predators throughout the year, according to a study published February 26, 2025 in the open-access journal PLOS One by George Balchin, William Hughes and colleagues at the University of Sussex, U.K., and Aquaplanet Dive Center, South Africa.

Eavesdropping on baleen whale songs in the Pacific Ocean reveals year-to-year variations that track changes in the availability of the species they forage on, reports a new study led by John Ryan, of the Monterey Bay Aquarium Research Institute (MBARI), U.S., published February 26, 2025 in the open-access journal PLOS One.

An Osaka Metropolitan University research team observing anemonefish in the field found they engage in interesting feeding behavior with their host sea anemones.

New Curtin University research has revealed how massive ancient glaciers acted like giant bulldozers, reshaping Earth’s surface and paving the way for complex life to flourish.

By chemically analysing crystals in ancient rocks, the researchers discovered that as glaciers carved through the landscape, they scraped deep into the Earth’s crust, releasing key minerals that altered ocean chemistry.

This process had a profound impact on our planet’s composition, creating conditions that allowed complex life to evolve.

The efficient architecture of our joints, which allows our skeletons to be flexible and sturdy, originated among our most ancient jawed fish ancestors, according to a study published February 25^th in the open-access journal PLOS Biology by Neelima Sharma of the University of Chicago and colleagues.

Scientists have uncovered lots of evidence that Mars had standing water billions of years ago, before the planet lost its atmosphere. But did it have oceans? Measurements obtained by ground penetrating radar aboard the Chinese rover Zhurong show beach deposits below the surface of Utopia Planitia, an area in Mars' northern plains that some think was an ancient ocean. The deposits, dipping like beach deposits on Earth, would have taken millions of years to form.
