Ancient seagrass holds secrets of the oldest living organism on earth

posidonia-oceanica 132456

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.

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

loneliest whale in the world

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.

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.
