Representing up to 80% of the zooplankton biomass, copepods are the most representative zooplankton type in the arctic. Up to 90% of this biomass is composed by a few species (Calanus hyperboreus, Calanus glacialis, Calanus finmarchicus, Metridia longas , \citealt{Falk_Petersen_2009}). Most of these species have developed a behaviour specific to extremely variable environments, allowing them to pursue their ontogenic development while avoiding unfavorable environmental conditions: the diapause.
