Short description
Chiavi di identificazione | Morfologia | Morfometria
Vertebre: 72 - 84. This medium-sized species is distinguishedd from its congeners except E. sheikoi, by the following characters: with flat and frustum-shaped denticles, elongated anterior and posterior lateral flank markings, and lower jaw with multicuspid teeth in mature males; differs from E. sheikoi by having a much narrower posterior flank marking, the shape and position of the caudal base marking, length of posterior caudal marking, the relatively larger gill slits, and the relatively more monospondylous, precaudal and total centra. May be confused with E. bigelowi, E, pusillus all three with frustum-shaped dermal denticles (Ref. 130841).
Smallest mature male examined is 32.5 cm TL. The largest female examined with developing ovaries and uterus (representing a maturing stage), suggesting that mature females apparently attain sizes larger than 40.0 cm TL. Some specimens have whole lanternfishes (family Myctophidae) inside their stomachs, as observed under X-radiographs (Ref. 130841).
