Morphological adaptation in the deep-sea benthic harpacticoid copepod family Cerviniidae
Por (1964) suggested that deep-sea harpacticoids were adapted to an "epipelic way of life", by means of a "gradual elongation of limbs". To test this hypothesis I examined four closely related Arctic species to determine if such a predicted gradient of morphological characteristi...
