Piezophile

From Wikipedia, the free encyclopedia

A piezophile is an organism which thrives at high pressures, such as deep sea bacteria or archaea.

The high pressures experienced by organisms in deep-sea trenches, for example, can cause the normally fluid cell membrane of these organisms to become waxy and relatively impermeable to nutrients. Evolution has forced these organisms to adapt in novel ways to become tolerant of these pressures in order to colonize deep sea habitats.
