World's biggest bacterium found in Caribbean mangrove swamp

Scientists have discovered the world's largest bacterium in a Caribbean mangrove swamp. Most bacteria are microscopic, but this one is so big it can be seen with the naked eye. The thin white filament, approximately the size of a human eyelash, is “by far the largest bacterium known to date”, said Jean-Marie Volland, a marine biologist at the Lawrence Berkeley National Laboratory and co-author of a paper announcing the discovery.
