Abstract
The limpet Lepetodrilus fucensis McLean is very abundant at hydrothermal vents on the Juan de Fuca and Explorer Ridges
in the northeast Pacific Ocean. This limpet is parasitized by an undescribed chitonophilid copepod throughout the limpets
range. The parasite copepodite enters the mantle cavity and attaches to the afferent branchial vein. The initial invasive stage
is a vermiform endosome within the vein that develops an extensive rootlet system causing an enlargement of the afferent
branchial vein. Subsequently, an ectosomal female body grows outside the vein to sizes up to 2 mm in width. Once a dwarf
male attaches, egg clusters form and nauplii are released. In over 3000 limpets examined from 30 populations, prevalence
averaged about 5% with localized infections in female limpets over 25%. After the establishment of limpet populations at
new vents, copepod prevalence increased over the succeeding months to 3 years. Host effects were marked and included
castration of both sexes and deterioration in gill condition which affected both food acquisition and the gill symbiont. There
was a significantly greater parasite prevalence in larger females which likely modifies the reproductive and competitive
success of local host populations.
