The Maldives may end up with perfect conditions for reef island building, but no new coral to build islands with.

Coral reefs are in trouble, but other marine species are also feeling the strain but are off the conservation radar.
Many Caribbean reefs are now dominated by sponges.
Marine sponges are ancient organisms that have survived mass extinctions. Many are more tolerant of climate change and may dominate over corals in future reef systems.

Field samples, satellite measurements and isotopic data have shed new light on corals' eating habits.
Researching the most resilient corals could help us find ways to better protect reefs in the future.
Building an artificial reef.
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.

Amphiprion ocellaris) navigates the anemones of the Andaman Coral Reef, India.
Our children all know the little clownfish Nemo, star of the Pixar film. But why does he have three stripes, rather than one or two? Developmental and evolutionary biology are revealing the answer.
Successive governments have seen the Great Barrier Reef not just as a scientific wonder, but as a channel to further economic development.
The $444 million awarded to the Great Barrier Reef Foundation has been criticised as a politically calculated move. But governments have been asking what the reef can do for them ever since colonial times.

Not everything humans put in the ocean is garbage. From walls of tyres to sunken sculptures, reef restoration is both a science and an art.
New findings from the Chagos Islands are a perfect parable for the Anthropocene.

Brindabellaspis had eyes on the top of the head, facing upwards, and a skull stretched into a long and broad snout. Although around 400 million years old, it was clearly a specialised fish.
Ingredients in many sunscreens are bleaching coral and harming marine life.
Scientists have discovered a natural sunscreen – made by microbes – that may be better for humans and the marine critters they are hoping to see.

On the eve of the March for Science, a marine biologist explains why she's returning from abroad to speak out for science in the Trump era.
Boat noise can interfere with the underwater communication of fishes and other marine animals.
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 increasingly bleached coral at Black Point on the Cobourg Peninsula is a worrying sign of what’s to come for other coral reefs in Australia.
Coral bleaching has struck the Northern Territory, adding urgency to the need for better national management strategies for our warming oceans.

Sea snakes spend their lives in the water, giving birth to live young at sea, so why are they only found in some of the world's oceans? The answer lies in a combination of climate and geography.
Researchers studied reef sands at Heron Island, Hawaii, Bermuda and Tetiaroa. In this photo, white areas show the predominance of sand on reefs.

Ocean acidification poses an increasing threat to the sediments that form the framework of coral reefs - within around 30 years, these carbonate sands may no longer be able to form.
