Scientists know very little about the social behaviors of great white sharks, but they're trying to learn more.

How Two Great White Shark ‘Buddies’ Could Change Perceptions of the Species

A pair of great white sharks named Simon and Jekyll have been swimming together for more than 4,000 miles in recent months

Researchers say that as climate change melts ice in Greenland, the influx of cool freshwater could weaken a network of ocean currents that affects Earth's weather.

A Vital Ocean Current System Could Collapse as Soon as 2025, Study Predicts

Climate change could halt the Atlantic Meridional Overturning Circulation sooner than thought, per a new paper, but some scientists are skeptical

The massive sharks known as megalodons ruled the oceans for some 20 million years.

Megalodons Were Warm-Blooded—and It Was a Blessing and a Curse

The giant sharks likely warmed some of their body parts, helping them grow massive but leaving them vulnerable to environmental changes, a new study finds

A recent incident suggests the boat-bashing behavior of orcas in the Strait of Gibraltar might be spreading to other groups.

Orca Rams Into Yacht Near Scotland, Suggesting the Behavior May Be Spreading

The incident occurred roughly 2,000 miles away from the recent encounters near Spain and Portugal

Analyzing DNA found in the water off Greenland, researchers have found the signs of species on the move.

The Atlantification of the Arctic Ocean is Underway

The discovery of a tiny fish far from its normal range is a poignant reminder of the changes that are already happening

Sargassum is not a new problem. But the mass of floating seaweed in the Atlantic Ocean is getting bigger, according to scientists.

A 5,000-Mile-Wide Mass of Seaweed Is Heading for Florida and Mexico

Known as sargassum, the algae can hurt tourism as it piles up on beaches and starts to rot

A father shows his son the awful-smelling algae hugging the shoreline of the St. Lucie River during a summer bloom in Stuart, Florida, in 2016. The algae fouled coastal waterways, created angry communities, closed beaches and had an economic impact as tourists and others were driven away by the smell and inability to enjoy the waterways.
