Prolonged withdrawal: A possible predator evasion behavior in Balanus glandula (Crustacea: Cirripedia)

Prolonged withdrawal: A possible predator evasion behavior in Balanus glandula (Crustacea:... 227 67 67 1 1 A. Richard Palmer J. Szymanska L.

Contact with potential predators including thaidid gastropods ( Thais emarginata, T. lamellosa ), and forcipulate asteroids ( Leptasterias hexactis, Pycnopodia helianthoides ) elicits significantly longer withdrawal durations than contact with an herbivorous gastropod ( Tegula pulligo ), a grazing, spinulosid asteroid ( Henricia leviuscula ) or a neutral, brown algal stimulus ( Fucus distichus ). By substantially attenuating the release of metabolites, prolonged withdrawal probably increases the likelihood of being bypassed by nonvisual predators relying on chemical cues to verify that barnacles are alive. The reduced response to the non-predatory species indicates that this is not a generalized response to gastropods or asteroids, but rather that it appears to be specific to potential predatory species. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Marine Biology Springer Journals
