Teleostei (teleosts) > Siluriformes (Catfishes) > Doradidae (Thorny catfishes) > Doradinae
Etymology: Hassar: Origin of the name was not specified by the author, but it is possible that it refers to the name commonly applied to certain catfishes in Guyana, such as Hoplosternum littorale or Hypostomus watawata.
Eponymy: Dr Burt Green Wilder (1841–1925) was an American comparative anatomist and naturalist. [...] (Ref. 128868), visit book page.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01380 (0.00789 - 0.02416), b=2.97 (2.82 - 3.12), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 2.8 ±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 (15 of 100).
