Short description Identification keys | Morphology | Morphometrics

This species is distinguished from the others species of the H. lacerdae group in having 42-46 scales along lateral line (vs. 38-43 in H. brasiliensis and 34-39 in H. curupira); 4-6 pores of the laterosensory system along the ventral surface of dentary (vs. always 5 in H. australis and 6-8 in H. lacerdae); angular shape of anterior profile of head (vs. rounded H. intermedius and H. australis) (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=0.00794 (0.00484 - 0.01305), b=3.18 (3.03 - 3.33), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 4.2 ±0.7 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (49 of 100).
