Sexual organs similar to what we see in sharks and rays today appeared many millions of years ago in much more primitive ancient fishes than was previously thought.

If we are truly invested in addressing the issue of marine plastic and offsetting the potential harms, we have to understand which fish eat plastic and which ones don't.
Australia's oceans are warming faster than the global average, and fish are moving south as a result.
How can marine preserves best protect sea creatures that move in and out of them? Two ocean scientists describe new thinking about designing marine protected areas.
Australia was thought to have some of the most sustainable fisheries in the world, but a recent count has found that fish numbers have plummeted by a third.
New study in mice shows that omega-3 in mother protects babies' gut health for life.
A 400 million year old fossilised fish skull gives us very early and previously unknown clues about how boney fishes evolved into the vertebrates we see today on Earth - including us humans.
Pregnant women should be reassured that eating fish is good for their baby and is very unlikely to cause autism.
New research suggests omega-3s from seafood to be more effective at reducing breast cancer risk than those from plant-based sources.
The noise from motor boats, sonar and other industrial activity interferes with the underwater chatter of fishes.
With coral reefs in crisis around the world, many organizations are working to restore them by growing and transplanting healthy corals. A new study spotlights techniques that help restored reefs thrive.
The seahorse dads carry the babies in a pouch.
Thousands of dirt roads crisscross the Brazilian Amazon, serving ranchers, loggers and miners. The area's fragile waterways — and the spectacular fish that live in them — pay a high price.
Using baited cameras scientists have captured some of the first underwater video footage of the elusive Greenland shark.
Artisanal fishers in Sri Lanka are throwing away more marine species than they keep.
Much of the world's ocean is teeming with 'cryptic' fish species, which are small and hard to spot. But a new technique shines a light on these fish, which may in turn help to keep our seas healthy.
Many living vertebrates have the ability to detect electric fields, especially in other animals when hunting. But what can the fossil record tell us about the origins of this sensory system?
Little skates that 'walk' across the ocean floor show how fish brains evolved to pave the way for working legs.
The Mariana snailfish lives nearly 27,000 feet underwater, but has features that help it adapt to intense water pressure and cold. Physiological limits may prevent fish from surviving in deeper water.
Sustainable fisheries tick all the boxes. They can fill your belly and your wallet, and generate less CO2 than conventional agriculture. So why is some integral funding for marine fisheries falling?
