As a key food supply declines, the endangered population of Southern Resident killer whales, known to frequent the Salish Sea off the coasts of Washington and British Columbia, is spending far less time in that region, a new study shows.

A new study led by researchers at British Antarctic Survey (BAS) discovered microplastics in krill (Euphausia superba), a small shrimp-like crustacean, and salps (Salpa thompsoni), a gelatinous marine invertebrate. 

Turtles and crocodiles are two of the world's most endangered animal groups, with approximately half of species globally threatened (International Union for Conservation of Nature, IUCN).

They are small, have a high reproductive output and live in the forests of Madagascar. 

New research shows that seabirds’ ingestion of the pollutant scars their insides—a new disease called “plasticosis”—and may disturb their microbiomes.

The oceans are heating up, and just 3°C of warming could significantly impact the development and growth of clownfish larvae, a new study finds.

The combined weight of every human is more than 10 times that of every wild land mammal put together, a new study finds.

Scripps Oceanography scientists and collaborators provide first-of-its-kind assessment of hypoxia, or low oxygen levels, across 32 coral reef sites around the world.

Come mating season, fishes off the California coast sing songs of love in the evenings and before sunrise. 

The deep sea is one of the least well-known areas on Earth, comprising multiple vulnerable ecosystems that play critical roles in the carbon cycle.
