Park (2000, p.55) emphasizes that the body size showed a wide range of variation, 8.41-11.00 in the female and 8.33-10.33 in the male. However, no morphological variation associated with the body sizes was detected. The largest specimens were found off California and the smallest off northwestern Africa.
