Ictaluridae (North American freshwater catfishes)
Etymology: Satan: The prince of darkness. Hube liked to name cave fishes with diabolic names based on the idea of hell being underground (Ref. 45335); eurystomus: From the Greek words Satan=Devil or Satan; eury=broad, wide; stomus referring to the mouth (Ref. 79012).
Eponymy: Named after the devil, and referring in the case of the blindcat to the species’ underground habitat. Günther’s use of a name meaning ‘Satan perch’ for the cichlids was probably inspired by Heckel (q.v.) having named a species as ‘Geophagus daemon’. (Ref. 128868), visit book page.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00250 - 0.01326), b=3.07 (2.87 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.4 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
