Anoxic environment - a loriciferan identified as an undescribed species of the genus Spinoloricus. The creature has specialized organelles so that it can survive without oxygen. Scale bar is 50 microns.
Dunaliella Algae. Lives in driest place on earth in Chile's Atacama desert. Grow on top of spider webs, capitalizing on dew
Hyperthermophiles - survive extreme heat - 205 degrees F or more
Halophilic - high salt tolerant organisms
Psychrophiles - survive extreme cold - 5 degrees F
Endophiles - organisms that live inside rocks or other things thought impermeable to life, like crevices of animal shells, or pores b/w grains of minerals. Have been found 2 miles below earth. Not much water, but some studies show they may survive feeding on surrounding potassium, iron or sulfur. While limited in some ways, they are protected from wind and water and solar radiation.
Deinococcus Radiodurans - named specifically for how much radiation it can. take. can take a 15,000 gray dose of radiation. 10 grays is enough to kill a human. 1000 grays kills a cockroach. ALSO survives extreme cold, dehydration, vacuum conditions, AND acids. Known in Guiness book of records as "worlds toughest bacteria"
