A preliminary health survey of the hermit crab, Pagurus bernhardus, on the southwest coast of Ireland.

During October and November of 2011 and 2012, 229 hermit crabs, Pagurus bernhardus, were randomly collected from the intertidal shore at three locations along the southwest coast of Ireland. This is the first survey to assess the health status of this crustacean in Ireland. Carapace length and the sex of each crab were recorded. Crabs were screened for parasites by histology and the intensity and prevalence of infection was determined. Crabs of varying carapace length were screened. The only parasite observed in the crabs was Microphallus sp., the first record of this digenetic trematode in P. bernhardus in Europe.
