SENSORY BIOLOGY: PACIFIC SHARKS 607 



SUMMARY 



Among island cultures of the southwestern Pacific, methods which are effec- 

 tive for attracting, repelling, or anticipating the behavior of sharks have been 

 developed through many generations of trial-and-error experience. Pro- 

 cedures for luring sharks by acoustic signals, exploiting chemical baits, and 

 inactivating sensory inputs show detailed insights into the sensory biology 

 and behavior of sharks. In addition, trained abilities to recognize certain 

 shark species and their behavioral patterns, on the basis of underwater sound 

 and visual cues, have been developed in some cultures. The effectiveness and 

 predictive accuracy of some of these methods suggest that careful analysis of 

 local knowledge and practices might suggest useful approaches for further 

 exploration by controlled scientific methods.
