Successful captures launched from short distance become more common as squid mature. Histograms for the number of successful copepod attacks by Group 1 squid are grouped according to attack dis- tance for the age classes defined in the legend of Figure 6: (A) Days 15- 23; (B) Days 26-35; (C) Days 41 -42. Basic attacks are encoded by dotted bars, arm intercepts by cross-hatched bars, and tentacular grabs by solid bars. In this experiment. Group 1 and 2 squid were reared simultaneously in adjacent tanks fed by a common source of seawater and were treated identically except for the feeding paradigm. Moreover, this experiment was a suc- cessful repetition of one carried out one year earlier. For these reasons, we postulate that the mortality increase in Figure 8. Analysis of unsuccessful attacks. Data for unsuccessful at- tacks are presented in a format analogous to that of Figure 6 for each age class of Group 1 squid: (A) Days 1-4; (B) Days 15-21; (C) Day 33; (D) Day 42. The coding of histogram bars for attack type is the same as that in Figure 7. Unsuccessful long distance attempts decrease as squid mature, while short-distance attempts increase in frequency. D. Days 1-4. Total Attack Distance (ML) B. Days 15-21.
