Figure 1: Total count of all live M. corona, the hermit crab C. vittatus in shells of M. corona, and empty shells of M. corona by season. No individuals were found during winter surveys.

Figure 2: Mean shell lengths of live M. corona (± SE) from summer and fall surveys. There was no significant different in shell lengths between seasons (ANOVA: p = 0.107).

Figure 3: Regression model illustrating no significant correlation between live M. corona shell length (cm) and prey oyster shell length (cm) (r2 = 0.123685; conch size = 11.390006 – 0.262133 x oyster size).
