Fish may not have eyelids to close, but they sleep – and perhaps even dream.
Academic rigour, journalistic flair

These small shrimp-like creatures are more than just whale food.
Fish can't read maps, and their eggs and larvae drift across national boundaries. Recent research shows that local problems in one fishery can affect others across wide areas.
Fish that live in the sea have found amazing ways to control the amount of water and salt in their bodies, and stay hydrated.
Media coverage of sharks often exaggerates risks to people, but more than 500 shark species have never been known to attack humans, and there's lots to learn about them.
They swim, they eat, they multiply.
In a study that cultivated coral 'gardens' with varying numbers of species, plots with more species were healthier. This finding could inform strategies to help coral reefs survive climate change.
Researchers have just discovered a new species of bacteria that cranks out a deadly toxin. In a common arrangement in the marine environment, a slug and alga both use this toxin for their own defense.
We know very little about the deep sea and how its inhabitants, including anglerfish, will respond to change. In fact, more people have walked on the Moon than have been to the bottom of the ocean.
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?
Tiny calcified formations inside fishes' ears can be used to trace a fish's life history – and potentially, how climate change has affected its growth and development.
Protecting forests and wetlands, which absorb and store carbon, is one way to slow climate change. Scientists are proposing similar treatment for marine animals that help store carbon in the oceans.
Nurdles are a raw feedstock used to make most of the plastic products we use everyday, but they're flooding the ocean as "mermaid tears".
Citizen science game offered clues to why shore crabs get greener as they grow.
New research shows how marine mammals ignore the rules of biology to thrive in the world's coldest waters
A few decades ago Boston Harbor was one of the nation's dirtiest water bodies. Now, healthier fish in the harbor underscore that a multibillion-dollar cleanup has succeeded.
Some media have reported shark numbers at 'plague proportions' in Australian waters. But a new analysis suggests the opposite: species such as hammerheads and white sharks have plummeted in number.
A massive new discovery this summer of miles of corals in deep waters off South Carolina shows how much we have yet to learn about life on the ocean floor.
Mangrove forests grow in the tidal lagoons of tropical coastlines and they could actually benefit from climate change. Here's what that means for us.
