Hisonotus iota differs from its congeners, except from Hisonotus hungy, by the lower lateral plate count 20–22 (mode 21) vs. 22–29 lateral plates, and by the lower vertebral count 25–26 vs. 27–32 vertebrae. It differs from Hisonotus hungy by having an infraorbital canal entering the infraorbital series via the compound pterotic vs. infraorbital canal entering the infraorbital series via the sphenotic (Ref. 80996).

Facultative air-breathing in the genus (Ref. 126274)

Estimates based on models

Fylogenetische diversiteitsindex (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).

Trofisch niveau (Ref. 69278): 2.3 ±0.1 se; based on size and trophs of closest relatives

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
