Figure 4, Zooplajikton Abundamce by Latitude . Since 

 the waters immediately north and south of the Equator contain en= 

 riched subsurface water, it is interesting to note that zooplankton, 

 which must have a rich "pasturage" to thrive, is particularly abun- 

 dant near the Equator, The amount of zooplankton at various lati- 

 tudes both north and south of the Equator is shown in the bar diagram 

 above. The numbers at the end of the bars indicate number of net 

 hauls made for each of the latitude categories. The longer bars near 

 the Equator indicate greater amounts of zooplankton; the top bar, 

 representing waters around Hawaii, suggests that the Island waters 

 may be less productive than equatorial waters.
