Zooplankton vertical migratory patterns are a classic example of optimal habitat choice. We hypothesize that zooplankton distribute themselves vertically in the water column according to an ideal free distribution (ifd) with costs such as to optimize their fitness.

The adaptive significance of diurnal migrations is unclear but likely evolved as a mechanism to avoid predation by fish, much of which is a visual process requiring light.
