Remarks.

Cerianthus incertus has a complicated taxonomic history and was originally described as C. danielsseni by Levinsen (1893) based only on its external morphology. Carlgren (1896) discussed this problem and, later, Roule (1905), based on specimens from nearby locations, described a new species using the same name. However, at this point, the name C. danielsseni became a homonym and was no longer available according to the rules of the International Commission on Zoological Nomenclature (ICZN). Thus, Carlgren (1932) suggested a new name ( Cerianthus incertus ) to solve both situations. Molodtsova (2014) postulated that C. incertus is a junior synonym of C. vogti , but there are no data available to confirm this hypothesis. Despite discussions on the past taxonomic confusion, this species is still understudied.
