Abstract

1. 1. The sensory capabilities of cuticular hair organs on the chelae of Homarus americanus were investigated. 2. 2. Type I organs responded tonically to displacement of the hair. 3. 3. Type II organs responded phasically to displacement of the hair. 4. 4. Activity not produced by Types I or II organs was elicited by vibration, suggesting that Type III or IV organs or both, are mechanosensitive. 5. 5. No responses were obtained to various chemical stimuli, nor to light onset or offset. 6. 6. We conclude that Types I and II and possibly Types III and IV, organs are mechanoreceptors employed in various behavioral contexts. © 1981.
