Abstract

Circumglobal distributions are widely accepted as commonplace among epiplanktonic species of Zooplankton and especially for those copepods occurring in warm oceanic waters (Sewell, 1948). Nevertheless, the warm-water belt lying roughly between latitudes 40° N and 40° S is not a continuous circle. Interruptions include a virtually perfect warm-water barrier, the Americas, separating the Atlantic and Pacific Oceans, the extensive Afro-European barrier separating the Atlantic from the Indian Ocean as far south as latitude 35° S and the mosaic of land masses and shallow seas comprising the Austral-Asian boundary intervening between the Indian and Pacific Oceans. These barriers appear a priori to be formidable deterrents to panmixis and in all likelihood they have prevailed in their relative positions at least since the end of the Tertiary (Darlington, 1965).
