Hydrothermal Worm
The image was taken by a Quanta Scanning Electron Microscope, which can magnify things up to one million times. The microscopic beast is a worm.

Found in a hydrothermal vent, an Earth fissure that puts water and hot gasses in contact, generating rich life environments. Worms like this don’t have a digestive tract, they can absorb the carbon compounds directly.
