Extremophiles

Extremophiles> Psychrophile> Grylloblattidae
Psychrophile-
Psychrophiles or cryophiles are considered to be an extremophile organism. They are capable of growing and reproducing in cold temperatures that range from −15°C to +10°C. When temperatures are as low as −15°C they could be found in pockets of very salty water surrounded by sea ice. They are present in alpine and arctic soils, high-latitude and deep ocean waters, polar ice, glaciers, and snowfields.

Grylloblattidae is a family of the extremophiles. They are wingless insects that live in the cold on top of mountains. They are usually called grylloblattids. They were discovered by T E.M. Walker and T.B. Kurata and concluded that most are nocturnal and appear to feed on detritus. They have long antennae (23–45 segments) and long cerci (5–8 segments), but they contain no wings.
