En la vida real son así y se llaman artemias:

“Evolutionary geochemist Felisa Wolfe-Simon, the lead author, and her colleagues found a strain of bacterium (GFAJ-1 of the Halomonadaceae family) that can grow in a medium abundant in arsenic and lacking phosphorus. The GFAJ-1 bacterium naturally resides in the arsenic-rich waters (200 uM) of Mono Lake located in California’s Eastern Sierra, and it belongs to a family of proteobacteria that is known to accumulate arsenic. It’s not remarkable that GFAJ-1 survives in high concentrations of arsenic, but what is startling is that it potentially integrates arsenic into its DNA and proteins.” 
“The microbe seems to be able to replace phosphorus with arsenic in some of its basic cellular processes — suggesting the possibility of a biochemistry very different from the one we know, which could be used by organisms in past or present extreme environments on Earth, or even on other planets.”
