geckos are found in a wide variety of habitats in the warmer parts of the world including rocky deserts mountains jungles rainforests grasslands and even in urban areas where it is common to find geckos in houses geckos can range in size from just a few centimetre to more than 50 cm in length
Acidophiles include certain types of eukaryotes, bacteria and archaea that are found in a variety of acidic environments, including sulfuric pools and geysers, areas polluted by acid mine drainage, and even our own stomachs. Normally, high acid levels destroy cells. However, acidophiles have evolved a variety of specialized mechanisms to maintain their internal cellular pH at a constant level (usually 7.2). These mechanisms include passive regulation (not requiring the cell to expend energy) and active regulation (requiring energy).
The creatures that live there are a type of extremophile known as thermophiles (thermo-meaning heat and phile meaning loving). On the other end of the temperature spectrum we find psychrophiles organisms that thrive in very cold environments, down to -18 C (less than 0 F)! The environments in which these two extremophiles live couldn t be more opposite. Thermophiles grow best at temperatures greater than 176 F (80 C) which can be found in places such as boiling hot springs or deep in the ocean near hydrothermal vents. On the other hand, psychrophiles prefer temperatures much less than 15 C for optimum growth and have been discovered living in snow, ice, and glaciers.
