FIGURE 9.— Component social interactions among age-sex classes of known bottlenose dolphins. Sex and length were determined 

 when the animals were captured. Age classes are based on body length-maturity data from Sergeant et al. (1973). Number of 

 individuals is presented under each age-class, n = number of observations. Adult female "Killer" was a dolphin that had an 

 atypical association pattern (see text).
