Abstract: The behavioral basis of the association between Acmaea asmi and Tegula funebralis has been investigated. The observations indicate that A. asmi is not attracted by a diffusible substance, but senses its substrate through contact with its tentacles. The critical substance(s) on the shell are easily destroued or dissolved by ethanol and slightly removed by distilled water. These factors are also present on Pagurus inhabited Tegula shells, but are not found on unihabited shells found on the beach.
