Teleostei (teleosts) > Siluriformes (Catfishes) > Amphiliidae (Loach catfishes) > Amphiliinae
Etymology: Amphilius: Greek, amphi = on both sides + Greek, leios = fat; caudosignatus: From caudo, meaning tail, and signatus, meaning striking, in reference to the distinctive caudal color pattern of this species.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [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 ±0.3 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec < 10,000).

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