A new study links a wave of bird flu to the deaths of more than 330 New England harbor and gray seals along the North Atlantic coast in 2022.

A deadly virus affects seals on the North Atlantic coasts of North America and Europe very differently. New research clarifies why.

Weddell seals are making all kinds of noise under the Antarctic ice, but at sound frequencies humans can't hear. Listen to an adjusted sample.

The loss of sea ice in the Arctic has opened pathways for a virus deadly to seals, otters, and other marine mammals, researchers say.

"We thought this large hole in the sea ice—known as a polynya—was something that was rare..."

Evidence that the seals in Alaska's Iliamna Lake are one of a kind could prevent a controversial mining project from going forward.
