Morphology | Morphometrics
soft rays: 8. Iotichthys phlegethontis can be distinguished by the following characters: no lateral line (rarely 1-2 pores at front); large scales (34-38 lateral); dorsal-fin origin behind pelvic-fin origin; slender peduncle; 8 anal-fin rays; pharyngeal teeth 2,5-4,2; large eye; short rounded snout; fairly deep, compressed body; color consists of olive above, black specks on back and side, gold stripe along blue side, white to yellow fins; and red-gold lower side, gold eye and anal fins in breeding males (Ref. 86798).
Inhabits marshes, ponds, vegetated areas of streams and lakes, usually over mud (Ref. 86798).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
Climate Vulnerability (Ref. 125649
): (0 of 100) .
