Ecology of Crepidula adunca

Main Ref.	Gallivan, G. and J. Danforth, 1999
Remarks	Occurs from middle to low intertidal zones; females live the majority of their lives on the outside of the shell of the Turban Snail (Tegula spp.), while males move from snail to snail. Filter feeder on plankton and detritus; captures drifting food with a mucous net (Ref. 312).
