An more specifically a Halophilic Archaeon?
I have no idea what this is.

An archaeon or archaean is any species of the domain Archaea.
To give a little more background, there are 3 domains of life - Archaea (used to be called Archaebacteria), Bacteria, and Eukaryota (which includes all plants, animals and protozoans).
Archaea are actually more closely related genetically to eukaryota than to bacteria, and it is believed that all eukaryotes (including us, of course) evolved from archaea rather than bacteria.
A halophilic archaean is a species of archaean that is able to tolerate very high concentrations of salt which would be lethal to other species (over 2M, 10 x that of ocean water). Not all halophilic species are archaeans though (some bacteria, fungi etc can live in high salt).
One group of archaeans, the halobacteria (which, as I say are actually archaeans, not bacteria) are able to tolerate extremely high concentrations of salt, to almost saturating levels, and the term halophile is sometimes used to refer to these species.

The halobacteria (also halomebacteria) are a class of archaea, found in water saturated or nearly saturated with salt. They are also called halophiles, though this name is also used for other organisms which live in somewhat less concentrated salt water. They are common in most environments where large amounts of salt, moisture, and organic material are available. Large blooms appear reddish, from the pigment bacteriorhodopsin. This pigment is used to absorb light, which provides energy to create ATP. The process is unrelated to other forms of photosynthesis involving electron transport, however, and halobacteria are incapable of fixing carbon from carbon dioxide.

If you really want to know, go to the site above. But I gotta tell you, it is some laborious reading, but will more than define the Halophilic Archaeon.

Creatures that live in extremely salty water, like the Dead Sea. Here is an example with pic:

Salt water single cell creatures.
