|Halobacteria sp. strain NRC-1, each cell about 5 μm long.|
The term halobacteria is a misnomer (mistaken name), because we now know the archaea are a different group from bacteria.
In taxonomy, the Haloarchaea are a class of the Euryarchaeota, found in water with salt. They are common in most environments where large amounts of salt, moisture, and organic material are available.
