In taxonomy, the Halobacteria (also Halomebacteria) are a class of the Euryarchaeota, found in water saturated or nearly saturated with salt. Halobacteria are now recognized as archaea, rather than bacteria. The name 'halobacteria' was assigned to this group of organisms before the existence of the domain Archaea was realized, and remains valid according to taxonomic rules. In a non-taxonomic context, halophilic archaea are referred to as haloarchaea to distinguish them from halophilic bacteria.
These microorganisms are members of the halophile community, in that they require high salt concentrations to grow. They are a distinct evolutionary branch of the Archaea, and are generally considered extremophiles, although not all members of this group can be considered as such.
Haloarchaea can grow aerobically or anaerobically. Parts of the membranes of haloarchaea are purplish in color, and large blooms of haloarchaea appear reddish, from the pigment bacteriorhodopsin, related to the retinal pigment rhodopsin which it uses as a source of energy by a process unrelated to other forms of photosynthesis.
In the South Pacific where the trade winds blow
They thought that the hula was a little bit slow
So they stepped it up with a go go go
And that's where they got that rock and roll
In the South Pacific now they're gettin' with it on the beach at Waikaki
And it's a lula when they try the hula with a rockin' rollin' beat
Rockin' and a rollin' in Waikaki rockin' and a rollin' in Waikaki
Rockin' and a rollin' in Waikaki rockin' and a rollin' in Waikaki
Don't stop just let her rock
[ guitar ]
Take me back where the trade winds blow
To the land of the hula where they never get old
And the gooney birds dance with a go go go
And the natives join in with a rock and roll
With me it's a riddle how they break in the middle and yet stay on the beat
But I wanna sway with 'em when I hear the rhythm of the rockin' hula beat
[ steel ]
Rockin' and a rollin' in Waikaki...
