Taxonomy Volvulella versus Rhizorus: Unfortunately many shelled opisthobranchs have been named on the basis of their shells alone, and this is a case in point. For the last 100 years there has been an on-going debate, unhappily still unresolved, over the names Volvulella Newton, 1891 [type species Bulla acuminata Bruguiere, 1792] and Rhizorus Montfort, 1810 [type species R. adelaidis Montfort, 1810] and whether they are synonyms. The shells certainly look the same but as they were described only on the shell it is very difficult. On top of that, Mediterranean and North American workers seem to prefer Volvulella while workers on the European North Atlantic and Australian - New Zealand regions have opted for Rhizorus.
