Figure 4. — Spawning sequence of an aggregation o{ Scarus 

 croicensis at Discovery Bay, Jamaica. A. A "weaving" group 

 above a larger "milling" aggregation. B. The weaving group 

 becomes tighter and makes more rapid turns. A few fish are 

 joining the group as it moves toward a spawning "rush." C. A 

 small group carries out a spawning rush (upper right) while a 

 second, larger group engages in weaving behavior (left side). 

 Part of the main aggregation is visible at the bottom of the 

 photography. D. Rushing (center) and weaving (left) groups 

 of S. croicensis. E. Return of group from a rush (upper left) to
