'''[[Psychrophiles]]''' are extremophilic organisms that are capable of growth and reproduction in low temperatures, ranging from −20 °C to +10 °C. They are found in places that are permanently cold, such as [[Antarctica]] and the deep sea. They can be contrasted with thermophiles, which are organisms that thrive at unusually high temperatures. Psychrophile is Greek for 'cold-loving'. | |||
Many such organisms are bacteria, but some eukaryotes such as [[lichen]]s, snow algae, fungi, and [[Antarctic midge|wingless midge]]s, are also classified as psychrophiles. Psychrophiles are protected from freezing and the expansion of [[ice]] by ice-induced desiccation and vitrification (glass transition), as long as they cool slowly. | |||
