One I managed to miss:

Giant amoebas found rolling on sea floor

Using a research submarine, marine biologists in the Bahamas have discovered large numbers of an unknown, grape-sized, single-celled animal slowly rolling across the sea floor.

"[It's] huge for a single cell. If I had cells that big I'd be six kilometres tall and weigh three trillion kilograms," said Sönke Johnsen, a biologist at Duke University in North Carolina, and the expedition's chief scientist.
