Top-down view of the head of a southern right whale calf (Eubalaena australis), showing the development of the whale’s callosities. Note that colonization of the main callosity by whale lice (Cyamis ovalis) is at an early stage. There also do not appear to be any barnacles ensconced in the callosity at this point. Photographed with the permission of the Department of Environmental Affairs, South Africa.
