Etymology: Hydrolagus: hydro-, combining form of hydor (Gr.), water; lagos (Gr.), hare, i.e., “water rabbit,” probably referring to three pairs of tooth plates, which tend to protrude from the mouth like a rabbit’s incisors (See ETYFish); macrophthalmus: macro-, from makros (Gr.), long; ophthalmos (Gr.), eye, referring to its large oval eyes (See ETYFish).

This species is distinguished by the following set of characters: slender body; short and bluntly rounded snout; relatively short head (HDL 24.2-24.5% BDL); relatively large eyes (EYL 30.9-34.2% HDL); oral and preopercular lateral line canals sharing a short common branch from the infraorbital canal; relatively large pectoral fins (P1A 36.5-40.8% BDL), extending posterior to the insertion of pelvic fins; trunk's lateral line canal without sinusoidal undulations; the anterior and posterior regions of second dorsal fin considerably taller than middle region; no anal fin; tail region elongate and slender (PCA 58.3-59.9% BDL); caudal-fin axis horizontal with the fin nearly symmetrical, epaxial and hypaxial lobes equal sized; coloration uniform brown across entire body, no white markings and bluish fins (Ref. 97389).
Body shape (shape guide): elongated; Cross section: angular.
