sentences:  Chun described the first specimen he caught, a male, as looking similar to the genus "Eledone", but with larger membranes, a differently shaped hectocotylus, and a differently shaped funnel organ (siphon).The specimen had "a sac-shaped body and very large eyes", with arms that "are folded back and have very large membranes which enclose the whole animal", and had a "characteristic pale coloration".Reiterating Chun, Guy Robson summarized the differences between "Eledone" and "V. togata" as "the possession of (a) a funnel organ composed of two separate pieces, (b) a sigmoid bend in the hectocotylized arm, and (c) the development of extensive lateral membranes on the arms".
