Fowler; personal communication of John Friell/Cornell University; oviraptor: Derived from the Latin ovum (ovi), meaning egg; and raptor, meaning a robber or plunderer, commonly used term for a predator, in reference to the peculiar dietary preferences observed in this species. A noun in apposition..

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 3; Anal soft rays: 5 - 6; Vertebrae: 29 - 31. Amaralia oviraptor differs from its only congener, A. hypsiura, by having more dorsal-fin rays (3 vs. 2); by having a lateral contact between middle and posterior nuchal plates (vs. middle and posterior nuchal plates not contacting each other laterally); by having feeble serrations along the distal portion of the anterior margin of pectoral-fin spine (vs. absence of serrations along the anterior margin); and by its longer cleithral process (17.4-19.5 % of SL, mean 18.2 % vs. 14.0-17.2 % of SL, mean=15.5 %) (Ref. 111083).

Feeds on both the eggs and developing embryos of other catfishes (Ref. 111083).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00324 (0.00134 - 0.00780), b=3.03 (2.83 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

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