    The purpose of this "paper" is to present a research project in progress on the physiology of Antarctic krill, with a focus on the response to environmental temperature variations. This study first focused on the study of heat shock proteins (HSP) and the comparative aspect quickly became essential for a better understanding of the mechanisms involved in relation to the environment. On the basis of this observation, this comparative approach has become the basis of the project and should soon focus on data from at least 25 different euphausiid species harvested in the Antarctic, Arctic and a latitudinal gradient stretching from the tropical environment to the waters of the Antarctic Polar Front. This ecophysiological study is as global as possible and combines transcriptomic (currently 17 transcriptomes are already available), metabolomic and lipidomic approach in the frame of French-Taiwanese and French-Chilean collaboration.
