Teleostei (teleosts) > Siluriformes (Catfishes) > Pimelodidae (Long-whiskered catfishes)
Etymology: Iheringichthys: Because of Hermann von Ihering, 1850-1930; He arrived in Brazil in 1880 and settled in Rio Grande as phisician and naturalist. Expert in birds, fishes and molluscs; syi: The Guaraní word syi means straight, alluding to the fine serration present on anterior margin of the pectoral-finspine. The name is applied as an adjective.
Eponymy: Dr Hermann Friedrich AIbrecht von Ihering (sometimes Jhering) (1850–1930) was a German-Brazilian zoologist, malacologist and geologist. [...] (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 6; Anal soft rays: 11 - 13. Can be diagnosed by the comparatively fine serration along the anterior margin of the pectoral-fin spine, an adpressed dorsal-fin remote from the adipose-fin origin, a large eye (23.2-31.2% of head length), narrow interorbital (16.2-23.0% of head length), long snout (42.0-51.0% of head length), long postorbital length (30.6-34.0% of head length), low adipose fin (4.8-7.8% of standard length), eye diameter 97.0-140.0% of interorbital length, and body with numerous, small dots irregularly scattered on flanks, especially marked on anterior half of flank (Ref. 89852).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00708 (0.00281 - 0.01786), b=3.09 (2.87 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.7 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 (12 of 100).
