Phagocytosis is the cellular process of engulfing solid particles by the cell membrane... in the immune system it is a major mechanism used to remove pathogens and cell debris.

Chemotaxis is the phenomenon in which bodily cells, bacteria, and other single-cell or multicellular organisms direct their movements according to certain chemicals in their environment.

Water Bears

Water bears are able to survive in extreme environments that would kill almost any other animal. They can survive temperatures close to absolute zero, temperatures as high as 151°C (303°F), 1,000 times more radiation than any animal, nearly a decade without water, and can also survive in a vacuum like that found in space.
