Our new research has more than doubled the known fossil record of seals in Australia.

Between 1986 and 2016, Kenya lost about 21 of its seagrasses.

Global long-term data simply doesn’t exist for jellyfish, so scientists struggle to predict, track and mitigate their potential effects.

We found plastic waste in pellets seabirds regurgitated and lining the nests where they raise chicks.

The spectacle of glowing dolphins should serve as a timely reminder of our need to conserve the darkness we have left.

As well as a stark warning about climate change, the disaster underlines the importance of wildlife monitoring.

The Great Pacific Garbage Patch, a floating accumulation of rubbish the size of a continent, has whales and dolphins in its heart.
Extreme flooding during Hurricane Maria in 2017 was hazardous for the Puerto Rican people. But a new study finds that it helped native fish populations rebound after years of drought.

Big storms with lots of flooding, like hurricanes Dorian and Maria, actually restore the Caribbean’s delicate balance between native and nonnative fish species, new research finds.

Fish that live in the sea have found amazing ways to control the amount of water and salt in their bodies, and stay hydrated.

Corals, mangroves and seagrass habitats have been affected by extreme weather events, and some may never recover.

They swim, they eat, they multiply.
Everything in an animal’s body is made out of cells. And these cells need chemicals, such as salt, in and around them to work properly. The chemical balance needs to be just right.

Some animals, such as ghost shrimps can even cope with water that is saltier than normal seawater. It’s all down to evolution.

Californians love their coast and strongly oppose offshore drilling. Will they support converting old oil rigs to artificial reefs – a policy that benefits both marine life and oil companies?

Phytoplankton are tiny, but they do important work.
A few days after baby molluscs come out from tiny eggs, they start building their shell layer after layer.

Molluscs that have shells - like pipis, clams and oysters - have to build their own shell from scratch. And they keep building it their whole life, using chemicals from the sea and their own bodies.
Some sea creatures are displaced by the desalination plant, but others actually grow.

Pumping very salty water into the ocean has surprisingly little impact on marine life.

Plastic bags are commonly mistaken for food by sea animals. They require a lot of energy and resources to be made, and have caused floods in some countries.

Marine heatwaves have had little attention until recently, but they’re already having large effects.
