With this orientation, the apices of the scutae, as well as the extended cirri of the barnacle, point in the direction of the whale's movement. Tightly packed clusters of barnacles in all stages of maturation, along with en- crusting cyamids, may occur from the tip of the rostrum to the blowholes, forming an almost continuous mantle. A few small clusters are unevenly distributed over the throat region and jaws (Fig. 3). Barnacles are sporadically distributed from the blowholes posteriorly to the tips of the flukes. Large, mature barnacles may occur singly and occasionally with one or two small adjacent ones. Barnacles on.
