Introduction


-The gastropod A. columbiana is common along the west coast of the United States in sandy, muddy and rocky substrata from the low intertidal to depths of 125 m

-Preliminary evidence suggest these snails are scavengers (Stone 1976) that use a long siphon to chemically explore their environment, but little is known about how they actually find food

-These snails create strong mucus trails that could be related to a trail-following foraging strategy (Davies et al. 2007)

-In the field, A. columbiana associate with feeding predators
