Adaptive Significance of Large Size and Long Life of the Chaetognath Sagitta Elegans in the Arctic
Zooplankton of high latitudes generally develop more slowly, reach a large size, and live longer than related forms in warmer seas. Existing explanations are reviewed and a new one offered. Where generation length is set by marked seasonality of food supply, as in the arctic, high fecundity and asso...
