The developmental rate of Euphausia crystallorophias larvae in Ellis Fjord, Vestfold Hills, Antarctica
Euphausia crystallorophias is the dominant Zooplankton species in the neritic seas of Antarctica, where it occurs in similar abundances to those ofEuphausia superba in more offshore areas. Despite its great abundance and probable ecological significance, few details are known of this species' d...
