Evolution is understood to be a species' total response to a large number of environmental factors.  One of these factors, even in the sea, may be solar UV radiation.  If so, one might relate a number of unique features of marine zooplankton to the selective pressures of this near-surface stress.  Some characteristics of marine zooplankton that may have been in­fluenced or even determined by UV radiation are the diel vertical migration, certain seasonal migrations and the seasonal occurrence of near-surface larvae, UV-absorbent cuticles, zooplankton coloration, zooplankton associations, and zooplankton shapes.
