Any xerophilic organism.
A xerophile, is an extremophilic organism that can grow and reproduce in conditions with a low availability of water, also known as water activity. Water activity is a measure of the amount of water within a substrate an organism can use to support sexual growth. Xerophiles are often said to be "xerotolerant", meaning tolerant of dry conditions. They can survive in environments with water activity below 0.8. Endoliths and halophiles are often xerotolerant. The common food preservation method of reducing water activities may not prevent the growth of xerophilic organisms, often resulting in food spoilage. Many mold and yeast species are xerophilic. Mold growth on bread is an example of food spoilage by xerophilic organisms. Examples of xerophiles include Trichosporonoides nigrescens, cacti, and tardigrades, which can survive for almost a decade without exposure to water.
