Everyone who cares about marine biodiversity, fish, fishers, coastal communities and fishing industry workers of today and tomorrow must push for the end of fisheries subsidies.
As climate change warms northern rivers and changes precipitation patterns, some types of cold-loving fish are failing.
International law does not meaningfully address biodiversity conservation in the high seas. We risk losing marine species before we have a chance to identify and understand them.
Reef fish vanish during marine heat waves, but may bounce back quickly on reefs that have few other environmental stressors.
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.
South Africa is home to four other seahorse species, but this was the first time a pygmy seahorse had been observed in South Africa, let alone Africa.
Biodiversity is often highest in places with human activity. The fishing industry has shown we can often have it both ways: maintain important livelihoods while protecting precious marine life.
Scientists thought there was only one sixgill sawshark species – until now.
Although less well known than its cousins, coral reefs and mangroves, seagrass plays a crucial role in climate change mitigation.
The Great Pacific Garbage Patch, a floating accumulation of rubbish the size of a continent, has whales and dolphins in its heart.
Oil spills from a project that’s designed to harness the economic potential of South Africa’s oceans are threatening the world’s largest remaining African Penguin colony.
Even the remote open ocean offers no escape from industrial fishing for sharks.
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.
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.
An effort to increase such areas can pose a particular threat to island overseas territories.
Coral reefs are in crisis around the world, and may disappear entirely. 3D printing is a new idea to help them – but it won’t be a cure all.
Why do whale sharks come together at just 20 locations around the globe?
It’s not just the land and people that have been badly affected by hurricanes.
Independent tests show that a wearable electric deterrent called a Shark Shield does indeed seem to live up to its name.
