Figure 84. — A group of 39 otters sleeping at St. Makarius Point East, 

 Amchitka Island, a favorite hauling ground for males. The many sleeping 

 positions are demonstrated. Some lie on their backs, others on the belly or 

 side, or curled nose-to-tail. (KWK 65-27-34) 



JUVENILES 



The foregoing paragraphs dealt primarily with adults. Segre- 

 gation of sexes is more pronounced among adults and subadults 

 than among independent or newly weaned juveniles. Among 35 

 juveniles taken in male areas, 80 percent were males (table 44). 

 In female areas, among 84 juveniles examined 63 percent were 

 females (table 43). 



Since juveniles are or were recently associated with their 

 motheis, it might be expected that a larger number would be 

 found in the female areas than in the male areas. The percent of 

 juveniles taken in both male and female areas was, however, the 

 same, about 26 percent (see footnotes, tables 43 and 44). This may 

 indicate that independent juveniles wander to all areas and mingle 

 With any group of adults. It also appeared, however, that juveniles 

 were more attracted to areas occupied predominantly by adults 

 of their own sex (20 percent female juveniles on the male areas 

 and 37 percent male juveniles on female areas). Perhaps because 

 of the recent mother-young relationship the proportion of young 

 males on the female area was greater than the proportion of young 

 females in the male areas.
