Abstract: A possible new marine cercaria found in the snail Batallaria attramentaria at Elkhorn Slough, California was described. A survey was performed on possible intermediate hosts and the cercaria's penetration behavior in one of them, Gillichthys mirabilis. As the cercaria aged, its activity and penetration ability decreased. The duration of successful cercarial penetration was dependent upon the levels of cercarial activity prior to attempted penetration.
