For the first time, a team of marine biology and environmental genomics researchers at NYU Abu Dhabi (NYUAD) and King Abdullah University of Science and Technology (KAUST) have demonstrated that epigenetic modifications in reef-building corals can be transmitted from parents to their offspring. This discovery, reported in a new study in the journal Nature Climate Change, not only enhances the biological understanding of corals, it also opens up new approaches to stem the loss of this foundation species of marine ecosystems.

Mussel species are dying en mass in rivers across the Pacific Northwest, Midwest and South—likely from unidentified pathogens

A retired naval officer dove in a submarine nearly 36,000ft into the deepest place on Earth, only to find what appears to be plastic

From sperm whales to dolphins, marine mammals in the eastern Mediterranean face a lethal threat from oil and gas exploration

Floating sunscreen, cloud brighteners and killer robots are just a few of the measures scientists are hoping will save the world's coral.

Rog Hanson created a secret habitat for seahorses in the coastal waters off Long Beach. He's come to see them about 1,000 times.

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).

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.

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.

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.

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.

An octopus has been filmed changing colour whilst sleeping, and scientists think it might be to due with it dreaming. So our eight-legged sea creature friends can dream, who knew? The footage, captured by PBS for an upcoming documentary Octopus: Making Contact, shows the mysterious creature asleep and changing from grey, to yellow, then almost invisible as it camouflages itself against the ocean.

Plastic is building up in the areas of the ocean where fish feed and grow, according to research.

Mining materials from the sea floor could help secure a low-carbon future, but researchers are racing to understand the environmental effects.

A new study shows the apex predators will flee their hunting grounds and won't return for up to a year when killer whales pass by

The "earplugs" of blue whales are preserved in their skulls throughout their lives, and keep a record of chemical changes in the animals' bodies.
