The larvae of four euphausiid species were collected from the Prydz Bay region, Antarctica, between 14 January and 6 February 1984,Thysanoessa macrura, Euphausia crystallorophias, E. frigida and E. superba. The most common species was T. macrura, occurring in all but one station. All larval stages from metanauplius to furcilia VI were recorded. E. crystallorophias was common in most inshore stations. The particularly high proportion of calyptopis I suggested that E. crystallorophias had only just started to reproduce, whereas the large numbers of T. macrura furcilia indicated that this species had been breeding for some time. Data also suggests that either the breeding season or growth rates of T. macrura varies within the locality. Although specimens of E. superba and E. frigida, mainly calyptopis larvae, were collected, neither species was particularly abundant.
