Rückenflossenweichstrahlen (insgesamt) : 8; Afterflossenweichstrahlen: 4 - 5. Extreme reduction of dermal plates on the dorsal surface of body, with just the ventral and mid-ventral rows normally developed; absence of dorsal-fin spinelet and nuchal plate; absence of the connecting bone and ligament between second dorsal-fin proximal radial and rib of sixth centrum; reduction of lateral line; loss of the infraorbital sensory canal; and absence of adipose fin (versus present in all species but H. vestigipinnis). Fourth branched ray of pelvic fin longest, reaching to middle of anal fin when depressed.

Trophic level (Ref.
69278): 2.3 ±0.1 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref.
