Giant Amoebas Discovered in Deepest Ocean Trench
OurAmazingPlanet.com ^ | 10/21/11

Posted on 10/21/2011 9:39:48 PM PDT by NormsRevenge

Gigantic amoebas have been found in the Mariana Trench, the deepest region on Earth.

During a July 2011 voyage to the Pacific Ocean chasm, researchers with Scripps Institution of Oceanography at UC San Diego and National Geographic engineers deployed untethered landers, called dropcams, equipped with digital video and lights to explore the largely mysterious region of the deep sea.

The team documented the deepest known existence of xenophyophores, single-celled animals exclusively found in deep-sea environments. Xenophyophores are noteworthy for their size, with individual cells often exceeding 4 inches (10 centimeters), their extreme abundance on the seafloor and their role as hosts for a variety of organisms.

Extreme environment, extreme creature

The researchers spotted the life forms at depths up to 6.6 miles (10,641 meters) within the Sirena Deep of the Mariana Trench. The previous depth record for xenophyophores was approximately 4.7 miles (7,500 m) in the New Hebrides Trench, although sightings in the deepest portion of the Mariana Trench have been reported.

Scientists say xenophyophores are the largest individual cells in existence. Recent studies indicate that by trapping particles from the water, xenophyophores can concentrate high levels of lead, uranium and mercury and are thus likely resistant to large doses of heavy metals. They also are well suited to a life of darkness, low temperature and high pressure in the deep sea.

"The identification of these gigantic cells in one of the deepest marine environments on the planet opens up a whole new habitat for further study of biodiversity, biotechnological potential and extreme environment adaptation," said Doug Bartlett, the Scripps marine microbiologist who organized the expedition.

Then I’ll make sure not to try to site a business anywhere near them.

They call them Giant, but they don’t give us a size? Are they big enough to eat a salmon, or big enough to eat a Destroyer?

It is one of my wonders why land animals were as big as they were; intuitively it would be assumed larger cells were in affect.

From the Article, they can reach a diameter of up to 4 inches.

Yep, I looked for a size, too.

Nanometers to lightyears, I've got a converter to something I can understand.

I did hear that it moves almost one furlong per fortnight.

Kind of interesting to learn that amoebas communicate with each other and will sacrifice themselves as a group to make a ‘stalk’ so some of the genetics survives when rations become short. When Einstein learned of this, he was astonished.

IIRC, the giant amoeba that ate the Enterprise was 11,000 miles across.

are they 4 inches on the sea floor? or do they expand to 4 inches when brought up to sea level?

I think it said just one of it’s cells exceeded 4 inches. Thus my curiosity was piqued. Reminds me of the song: “The Amoeba that Ate Cincinnati”

Four inches. That's okay then.

When I was in high school, there was a one-act play that scared the bejeebers out of me. The Amoeba. The four-foot amoeba. Big enough to skeletonize its victims in three seconds of pitch black.

Very well staged. Still creeps me out more than thirty years later - Hallowe'en coming up again.

So four inches is just fine - you don't think they swarm like piranhas, do you?

Go rent Disney’s “The Black Hole”.

That’ll purge the other one for a while.

How do you think Obama was elected? They are a liberals dream.. even after you register them to vote they can divide and now there are two.. then four.. then eight...

sort of like some districts in Philly where there are more voters than citizens... same thing I guess..

And most likely they will also NEVER have a super bowl or baseball world champion either...
