Additional records of barnacles (Chelonibiidae, Coronulidae and Lepadidae) from stranded turtles around the British Isles

Additional records of barnacles from turtles in British or Irish waters are presented. These include six turtle barnacle records that had been overlooked in a previous review in 2022 and four new records since 2022. The first records of the barnacles Chelonibia testudinaria from a green turtle (Chelonia mydas) and of Platylepas hexastylos from a Kemp’s ridley turtle (Lepidochelys kempii) in U.K. waters are discussed. Details are also provided on Lepas anatifera and L. hillii specimens from a loggerhead turtle (Caretta caretta) which stranded on the Isle of Man in January 2016 and notes on new records of Lepas spp. from loggerhead turtles in Cornwall and Guernsey in 2022 and 2023. The susceptibility of loggerheads to goose barnacle infestation is discussed, as is the occurrence of Columbus crabs (Planes minutus) on loggerhead turtles.
