Default GRAPE Sized Amoebas?

Okay, they're a distant relative, but they're still a single celled organsim.
Quote:
Slowly rolling across the ocean floor, a humble single-celled creature is poised to revolutionize our understanding of how complex life evolved on Earth.

A distant relative of microscopic amoebas, the grape-sized Gromia sphaerica was discovered once before, lying motionless at the bottom of the Arabian Sea. But when Mikhail Matz of the University of Texas at Austin and a group of researchers stumbled across a group of G. sphaerica off the coast of the Bahamas, the creatures were leaving trails behind them up to 50 centimeters (20 inches) long in the mud.
"There are things on heaven and earth undreampt of in your philosophy" indeed. That this species could be almost 2 billion years old has my jaw on the floor.

Good find Tuckerfan. I found this the most interesting:
Quote:
The trouble is, single-celled critters aren't supposed to be able to leave trails. The oldest fossils of animal trails, called 'trace fossils', date to around 580 million years ago, and paleontologists always figured they must have been made by multicellular animals with complex, symmetrical bodies.
[...]
"If these guys were alive 600 million years ago, and their traces got fossilized, a paleontologist who had never seen this thing would not have a shade of doubt attributing this kind of trace to the activity of a big, multicellular, bilaterally symmetrical animal," Matz said.
Of course, there's a big IF in there, but it might help improve our understanding of the fossil record one day.

The only monster devouring Cleveland today is the Lake Erie Snow Machine.

Grape sized unicellular organisms?

Wow...

There are some very big foraminfera out there, which are protozoans. I have seen seagreas beds coated with Marinopera which are the size of a small coin. Mind you, they do cheat, being poly-nucleate and having zooanthellae.

Somehow I think the article wasn't about a giant ameoba.

But many proteous have many nucleous without defined cell walls.

So I think they cheated on the article making sound like giant ameoba wirh one nucleous.

But as a easy way to raise a giant ameoba is
http://en.wikipedia.org/wiki/Chaos_(amoeba)

'Chaos is a genus of giant amoebae, varying from 1-5 mm in length. They are closely related to Amoeba, and share the same general morphology, producing numerous cylindrical pseudopods. However, Chaos have several hundred nuclei, while Amoeba only have one. '

Exposing your pet Chaos Amoeba to gamma rays will not make it bigger or more intelligent.

But if successfull report it to 'Men in Black' The website if it turns hostile.

Maybe a extraterrestial life form just playing on your hospitality.

Since they are mostly calcareous exoskeleton I suspect they would taste like a piece of crab shell.

Most funguses are a bit like that, come to think of it. Word of the day: hypha.
