Diurnal vertical distribution of S. diaphana determined by rate of capture with depth during day (D) an night (N). A ^ Southern Ocean; B ^ Gulf of Guinea; C =: Gulf of Mexico and Caribbean; D =: NE Atlantic. sample taken in the North Pacific; this species occurs in small numbers off lower California and has been reported abun- dantly southeast of Hawaii; a large popu- lation extends across the South Pacific from Chile to about 160°E longitude. Vertical distribution (Fig. 60): Distrib- uted between 400 m and 1200 m; major concentrations occur between 700 m and 900 m; no diurnal movement or marked geographical depth xariation could be dei tected. Geographic variation. With the excep tion of the Pacific southern ocean popm lation, little geographic variation could b* detected; characters were few and sampl( sizes small, however (Table 17, Fig. 61); The Southern Ocean population is quit«| distinct and certainly represents an ini stance of incipient speciation.
