Teleostei (teleosts) > Siluriformes (Catfishes) > Bagridae (Bagrid catfishes)
Etymology: Leiocassis: Greek, leios = smooth + Greek, kassis = similar to cinnamon (Ref. 45335); aculeata: Derived from the Latin aculeatus, meaning sharp-pointed or stinging, in reference to the large spines of this species when compared to Leiocassis micropogon..

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 7; Anal soft rays: 14; Vertebrae: 38 - 39. Distinguished from congeners, except Leiocassis poecilopterus, in having the posterior tip of the supraoccipital process in contact with the nuchal plate. Further differs from L. micropogon in possessing a deeper body (19.8-20.8% SL vs. 10.0-18.9); and from L. poecilopterus in having a longer adipose fin (15.8-16.6% SL vs. 12.9-15.0) and longer dorsal (20.8% SL vs. 15.5-18.4) and pectoral spines (17.9-18.7 % SL vs. 14.5-17.5) (Ref. 55439).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5002 [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): 3.4 ±0.3 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).
