Again, catch information gives no insight into the effects on smaller sizes that are not collected in the fishery. However, at Moss Landing Beach, Stephenson (1977) documented the abundance and size distribution of Pismo clams before and after the otters arrived. His data show a significant decrease only in the largest clams. Otters may use visual or tactile cues to locate Pismo clams, but in either case large shallow-burrowing clams are probably easier to locate than small ones. Pismo clam populations fluctuate widely in time and space even in the absence of sea otters.

And thus present uncontrolled contrasts, the consistent results suggest a positive relationship between dive times and depths of prey in the sediment. 2 Prey Resilience In addition to prey resistance, the other component of prey vulnerability is the resilience of prey populations after exploitation by sea otters. There is essentially no information on how different species of soft-sediment prey recover from sea otter predation. The Pismo clam typifies this lack of knowledge. This species has pelagic larvae that live in the plankton several weeks before settlement (Fitch 1950).

The water clarity and high number of cancer crabs also permits scuba divers to quantify their abundance and population structure. We predict that cancer crabs have little measurable effect on the numerous polychaete worms in this community, but may influence the species composition, abundance, and size structure of bivalve prey as Virnstein (1977) documented for the blue crab and Peterson (1983) showed for Cancer anthonyi. As a result, otter predation on cancer crabs may have an indirect effect on in faunal communities.
