FIGURE 4. —Average vertical abundance profiles of Hypsoblennius spp. andParalichthys californicus during the study of daily vertical migration 

 off San Onofre, Calif. The depth ranges of the five sampling strata are the averages (based on four to six profiles) for each sampling period. Note 

 that the horizontal (abundance) scale varies.
