In a later study on the same research topic of the Metridium complex, another set of authors asks, “how did an organism as conspicuous as M. giganteum escape formal description until now?”. The question is not really a fair one, as the authors of the 1982 paper do describe its presence, but just fail to provide a name for it. Fautin et al. 1989 The Wasmann J Biol 47: 77.
