Growth and shrinkage in Antarctic krill Euphausia superba is sex-dependent
Abstract: The ability of Antarctic krill Euphausia superba Dana to withstand the overwintering ... period is critical to their success. Laboratory evidence suggests that krill may shrink in body length ... during this time in response to the low availability of food. Nevertheless, verification that krill can ... sources of winter krill population data is from commercial vessels. We examined length-frequency data ...
