Etymology: Ilyophis: Greek, ilyos, -ou = cave + Greek, ophis = serpent (Ref. 45335).
Eponymy: Jacques Blache (1922–1994) was a French ichthyologist who worked for the Office de la Recherche Scientifique et Technique d’Outre-Mer (ORSTOM) in Kampuchea (1948–1953) and in various African countries including Chad, Congo and Senegal (1953–1973). [...] (Ref. 128868), visit book page.

Description synthétique
Clés d'identification | Morphologie | Morphométrie
Body large, robust; either partially scaled or naked body. Broad, angular posterior nostril flap, with flap and nostril rim ornamented with numerous leaf-like marginal projections. Very oblique gill slits (ca 30° relative to horizontal axis of the body).
Body shape (shape guide): eel-like.
Found on the lower continental slope at 1,465-2,070 m (Ref. 6726). Carnivorous, feeding primarily on galatheid crustaceans (Ref. 6726). Probably spawn in June-July (Ref. 6726).
