Ancient seagrass holds secrets of the oldest living organism on earth

A meadow of the seagrass plant Posidonia oceanica, which spreads by creating clones of itself.

It’s big, it’s old and it lives under the sea — and now an international research collaboration with The University of Western Australia’s Ocean’s Institute has confirmed that an ancient seagrass holds the secrets of the oldest living organism on Earth…

Ancient giant Posidonia oceanica reproduces asexually, generating clones of itself. A single organism — which has been found to span up to 15 kilometres in width and reach more than 6,000 metric tonnes in mass — may well be more than 100,000 years old.

The combined effects of climate change, over-exploitation, pollution and habitat loss will cause the mass extinction. 

Ocean life is at an imminent risk of the worst spate of extinctions in millions of years due to threats such as climate change and over-fishing, according to a study led by the International Programme on the State of the Ocean (IPSO).

Military Hopes to Create Squid-like Camo

squid-like camo

Scientists are studying how squid and other cephalopods change color and pattern of their skin to blend in with their environment.

Octopuses, squid, and cuttlefish have the ability to instantaneously change the color and pattern of their skin to blend in with their surroundings.  This has caught the eye of the U.S. military and now its goal is a new generation of high-tech camouflage.

Loneliest Whale in the World Sings at the Wrong Frequency

World’s loneliest whale. 

We’ve heard about whales suffering from loneliness due to overhunting. There’s simply fewer of their species for them to communicate with. But what about a whale who sings at the wrong frequency? One whale, recorded since 1989 and tracked since 1992, sings at a frequency of 51.75 Hz, whereas others of her kind sing at 15 to 25 Hz. She’s lonely because no one else can hear her.

Dust Blown Into the Oceans From the African Desert May Increase Risk of Seafood Poisoning


Dust from the African Desert can increase the growth of bacteria that are the main cause of food poisoning from seafood.

Researchers have found that harmful bacteria found in seawater flourish in the presence of dust that comes from the Sahara desert in western Africa, as well as other areas of continent.


Busy Microbial World Discovered in Deepest Ocean Crust Ever Explored

microbial life interactions going on in the deepest ocean crust ever explored!

The first study to ever explore biological activity in the deepest layer of ocean crust has found bacteria with a remarkable range of capabilities, including eating hydrocarbons and natural gas, and “fixing” or storing carbon.

New Device Detects Objects Through Bubble Clouds

Detection of targets in bubbly waters are key goals of shallow-water sonar.

Scientists at the University of Southampton have developed a new kind of underwater sonar device that can detect objects through bubble clouds that would effectively blind standard sonar.
