Reef-building corals can make unexpected recoveries from climate change-induced destruction. It turns out that some corals only look dead when exposed to unusually warm water. Instead, the coral’s polyps shrink and retreat into their hard skeleton, making the reef appear dead, before recolonising the skeleton when conditions are better. It is a survival strategy never seen before in today’s corals – but it may not help the corals as the climate continues to change.

Experts say this could have a devastating effect on wildlife

The red tide that plagued Florida for 15 months — killing marine life and causing respiratory problems for humans — is back, The Associated Press reported Saturday.

Coral reefs are the foundation of ocean life, and yet 50% of them have been lost. Here’s why coral reefs are dying and what one group is doing to stop it.

Horseshoe Crab blood is an irreplaceable medical marvel, and biomedical companies are bleeding thousands of crabs and throwing them back in the ocean.

ANTARCTICA scientists made a stunning discovery 3,500 metres below the ice, leading one to state they had "never seen anything like this before," a documentary revealed.

The "Great Pacific Garbage Patch" cleanup is finally underway. The system uses natural currents of the sea to passively collect plastic debris.

We all know sharks have had a bit of an undeserved bad rap (thanks Jaws!). But if you're one of those people who find sharks scary, this newly identified species of pocket shark might just change your mind.

Scientists believe they may have discovered the world’s oldest living vertebrate.

A five-year study in Indonesian waters has confirmed that wild-roaming reef manta rays (Manta alfredi) form selective bonds with other rays, providing evidence of structured social relationships. Dwarfing humans who are lucky enough to swim near them, mantas are the largest rays in the ocean, with two recognised species – the reef manta and the giant manta (Manta birostris).

Five-yearly report says climate change is escalating the threat and window of opportunity for action is now

A nightmare at 6,000 feet.

An analysis concluded that Earth’s oceans are heating up 40 percent faster on average than a United Nations panel estimated five years ago, a finding with dire implications for climate change.

Underwater robot has delivered over 100k baby corals in attempt to restore part of the Great Barrier Reef

Increasing ship traffic, sonar and seismic air gun blasts now planned for offshore drilling may be disrupting migration, reproduction and even the chatter of the seas’ creatures.

The salt and chemicals in the brine left over from desalination can threaten local marine ecosystems

Research shows how the Antarctic blackfin icefish differs from its close relatives on the genetic level.

In the Mariana Trench, the lowest point in any ocean, every tiny animal tested had plastic pollution hiding in its gut.

Even the largest ecosystems have limits when it comes to recovering from the impact of climate change, according to new research from Australia.

The creatures are not just incredibly clever, but also carnivorous, meaning a huge amount of wild fish will be caught to feed them, putting pressure on the ecosystem.
