Rather than breathing in and out through the mouth, fish use a one-way system, passing water in one direction over their gills.

It's time to listen to warnings from the people of the Pacific.
Hurricane Harvey destroyed the fishing infrastructure of Aransas Bay and reduced fishing by 80% over the following year. This removed humans from the trophic cascade and whole food webs changed.
Companies are eager to mine the deep ocean for valuable mineral deposits. But scientists are concerned about impacts on sea life, including creatures that haven't even been discovered yet.
Towns and cities create an orange glow on the horizon at night. It's so widespread that it even disturbs sea creatures.
Too many small yachts and speedboats are simply being abandoned to shed toxins and microplastics into the sea.
The discovery that such a common animal can rapidly produce vast numbers of nanoplastics is particularly worrying.
The extraordinary story of a stingray, its discovery and its uncertain fate in the Yemen war.
Wild dolphins are fast, smart and hard to study, but it is important to understand how human actions affect their health. So we are building a drone to sample hormones from the blowholes of dolphins.
Microscopic ocean phytoplankton feed a "biological pump" that carries carbon from the surface to deep waters. Scientists have found that this process stores much more carbon than previously thought.
Researchers are using a newly developed satellite tag to study previously unknown aspects of tiger shark reproduction. This approach could be used on other difficult-to-study shark species.
The Deepwater Horizon oil disaster catalyzed a decade of research on oil contamination in the Gulf of Mexico, from surface waters to the seabed, with surprising findings.
You won't see a blue shark near the beach, but thanks to 50 years of tagging data, scientists are learning about their wide-ranging lives at sea.
White's seahorse in Sydney uses seahorse hotels as temporary residence while their natural habitats recover.
How did whales that feed on tiny prey evolve into the largest creatures on Earth? And why don't they get even bigger?
Fish may not have eyelids to close, but they sleep – and perhaps even dream.
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.
