Short description Morfologia | Morfometria

Raggi dorsali molli (totale): 8; Raggi anali molli: 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.

Biologia     Glossario (es. epibenthic)

Facultative air-breathing in the genus (Ref. 126274); Occurs in small, shallow rivers with clear water and moderate to strong water current. Usually found among the bottom rocks and stones.

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00759 (0.00337 - 0.01709), b=3.12 (2.93 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.3   ±0.1 se; based on size and trophs of closest relatives
Resilienza (Ref. 120179):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
