    What distinguishes Cryptolepas rhachianecti from Coronula & Cetopirus?
    A primary feature distinguishing Cryptolepas rhachianecti from Coronula and Cetopirus is the absence of a complete outer wall to the shell, which in the latter two genera is formed by the merging of T-shaped flanges at the ends of the lamellar folds and which serves to create coring chambers that envelop prongs of the host's skin.

    Is rhachianecti a Symbion of a gray whale?
    Overharvesting led to the final collapse of this population by sometime in the 18 th century, however, and today C. rhachianecti is found only in the North Pacific, where it is a host-specific symbiont of the gray whale (Newman and Ross, 1976; Newman and Abbott, 1980; Scarff, 1986; Bradford et al., 2011; Hayashi, 2012 ).

    Are Cryptolepas derived from Coronula and Cetopirus?
    Cryptolepas traditionally has been suggested to have derived from the lineage that includes Coronula and Cetopirus, with the major differences in shell morphology seen in Cryptolepas interpreted as degenerative changes related to the more embedded, protected station of the shell in the host's skin (Pilsbry, 1916; Monroe, 1981 ).
