Summary[edit] Description: The ventral view of this Crepidula abdunca shows why it is called the slipper shell. Date: 19 January 2008, 15:14. Source: Slipper Shell. Author: Jerry Kirkhart from Los Osos, Calif.
Here are two single males and a mated pair (younger male on older female) atop their host snail. Slipper snails are filter feeders and sequential hermaphrodites, first male, later female. There is no free-living larval stage; juveniles are pushed out from beneath their mother's foot. Depth 10 m.
