The biology and ecology of an Antarctic species Oncaea antarctica, which belongs to the Cyclopoida, was reconstructed from analyses of vertically-stratified zooplankton sets of samples taken with a 150 *m and 250 *m-mesh net during the day and at night, during 3 austral seasons (sum-mer - December 1985, autumn - April 1988, winter - June-August 1989). The plankton material was collected at stations located in Croker Passage (Antarctic Peninsula). Inhabiting meso- and bathypelagic waters, O. antarctica was one of the most numerous cyclopoids of the family Oncaeidae, making up 50% of all Cyclopoida in winter. Females carrying egg sacs and copulating pairs of this species were present during all three seasons investigated.
