  Whale Barnacles

  Coronulidae is a family of barnacles (Cirripedia) commonly known as whale barnacles, though their host associations extend beyond cetaceans to include sea turtles and crocodilians. Members are obligate epizoic species that attach to mobile marine hosts during their free-swimming larval stage. The family includes the genus Chelonibia, which exhibits exclusively passive feeding behavior—a unique trait among barnacles where the species relies entirely on host-generated water currents rather than facultatively switching between active and passive feeding modes.
