DURATION OF PELAGIC STAGE (DAYS) 



Figure 2. --Comparison of the duration of the pelagic stages for species showing 

 different zoogeographic distributional patterns. Values on the abscissa are 

 adjusted (see text) to convert pre-transition increment counts to pelagic 

 duration. Open circles = means for species occurring in the Western and 

 Central Pacific only; solid triangles = species whose range includes the 

 Hawaiian Islands; solid squares = species distributed trans-Pacif ical ly. 

 but one trans-Pacific species are found also in the Hawaiian Islands.
