Rayons mous dorsaux (Total) : 10; Rayons mous anaux: 11 - 12. Polyipnus fraseri is distinguished from all other Polyipnus by the presence of a unique posterior preopercular spine, absence of ACA photophores, and only four ACB photophores at SL over 2 cm (Ref. 26382).
Body shape (shape guide): short and / or deep.
Minimum depth from Ref. 58018.
