Abstract

The discrete, ecologically distinct, distributional patterns of the 3 closely related, allopatric species reflect the influence of a number of biological and physical factors. T. megalops is confined to the highly productive Atlantic subarctic and the highly productive areas of the North Atlantic temperate region. T. maculata is restricted to the area of year-round, high productivity in the E tropical Atlantic. T. pellucida is distributed circumglobally in the mixed and fringing waters of the Southern Subtropical Convergence. The species display similar patterns of ontogenetic descent from near-surface waters to midwater depths of c1000 m to >2500 m where the animals mature, mate and spawn. Variations in the maturity-related morphological features among the species suggest differences in behavioral patterns for courtship and copulation. -from Author
