Scientists discovered a new species of largest bacteria visible with the naked eye. 

The bacteria, found in the Caribbean mangrove. This is thousands of times larger than most bacteria and the biggest seen to date.

The thin, vermicelli-like bacteria grow up to 1 cm (0.4 inches) in length, That's about 5,000 times bigger than most others and about 50 times bigger than any other known bacteria.

The researchers’ say the cell has a structure that’s unusual for bacteria. The acquisition of this large central vacuole definitely helps a cell to bypass physical limitations.

It would be like a human encountering another human as tall as Mount Everest.

It opens up the question of how many of these giant bacteria are out there — and reminds us we should never, ever underestimate bacteria.
