Etymology: Hoplias: Greek, hoplon = weapon (Ref. 45335); curupira: Named for Curupira, a mythical creature of the Brazilian folklore that protects the forest. A Curupira is a small Amerindian child characterized by having its feet turned backwards, making it difficult to follow its tracks; noun in apposition.

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 13 - 16; Anal soft rays: 8 - 10. This species is distinguished from other members of the Hoplias lacerdae group by having the following characters: laterosensory canal along the ventral surface of dentary always with 4 pores that become gradually subdivided into four patches of multiple pores in specimens larger than 6 cm SL; head and body with a dark brown ground coloration; scales on the lateral line 34-39; snout width 13.1-27.2% of HL; and interorbital width 16.0-35.5% of HL. Differs from Hoplias brasiliensis and Hoplias intermedius by its anterior profile of head rounded in lateral view vs. angular (Ref. 81195).

Inhabits large rivers and igarapés. Occurs usually in pairs. Exhibits diurnal as well as nocturnal habits and preys on various insects, larvae, small fishes, shrimps, worms and fruits (Ref. 81195).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00661 (0.00297 - 0.01469), b=3.12 (2.93 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.7 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 to moderate vulnerability (26 of 100).
