Short description Identification keys | Morphology | Morphometrics

Vertebrae: 34. Distinguished by the following combination of apparently apomorphic characters: posttemporal bone is absent; extrascapular reduced to a bony latero-sensory canal; epioccipital bridge absent; parietal branch of the supraorbital latero-sensory canal restricted to the frontal bone; supraorbitals absent; medial process on rib of fifth vertebral centrum present as a simple bony spine; a well-defined foramen is present on the posterior region of the medial lamina of the coracoid; fifteen or more dorsal-fin rays present; lateral line incomplete; discrete bands or spots absent, except for a diffuse humeral blotch; origin of the anal-fin base located slightly posterior to or in advance of a vertical line drawn from the posterior termination of the dorsal fin; teeth of all jaw bones conical; body slab sided, relatively short; the anterior portion of pterotic latero-sensory canal does not enter the sphenotic; sphenotic bone, state 0 = sphenotic separated from the posttemporal fossa by presence of an articulation of the parietal and pterotic, state 1, sphenotic enlarged posteriorly and forming a part of the anterior border of the posttemporal fossa; circuli are present on the posterior or apical field of the lateral body scales (Ref. 34069).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [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): 3.2 ±0.3 se; based on size and trophs of closest relatives

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