Dear MARMAM community, Several species of acorn barnacles occur on whales worldwide. The most commonly reported is Coronula diadema, a globose crown-shaped species up to 6 or 7 cm in diameter. I am seeking specimens (shell and tissue) of other, apparently less prevalent species that are conical, straight-sided, or flattened (i.e. Coronula reginae and Cetopirus complanatus). Indications are these species occur mostly with hosts from southern oceans. Samples preserved in ethanol (not formaldehyde) are desired. If you have potential samples to share please contact me offline at the address below. I will be happy to supply you with my NMFS collecting permit, advise on preservation and shipment, and to pay for sample shipment. Kind regards, John Zardus John D.
