Malaclemys terrapin The occurrence and effects of barnacle infestations on 2 populations of diamondback terrapins were studied from 1977-1979 at the Merritt Island National Wildlife Refuge, Brevard Co., Florida . Three species of barnacles were found on Malaclemys: Balanus eburneus, Chelonibia manati and C. testudinaria. Of 125 turtles examined, 76% were infested by barnacles. Barnacles settled on the carapace of turtles significantly more frequently than on the plastron. Infestation rates differed sharply between the 2 populations. No differences in fouling rates were found between the sexes. The major effects of barnacles on Malaclemys were interference with nesting activity and shell erosion. In a few cases, such erosion was servere enough to cause fatal injuries to turtles. Barnacles infesting should be considered parasites, rather than commensals.
