Short description Morphology | Morphometrics

A medium-sized species with the following characters: head 7.8-12.5% TL in height, trunk width 13.0-16.8% TL; origin of first dorsal-fin mostly over posterior of pelvic-fin base; prenarial 3.6-4.9% TL in length; preorbital snout length 1.5-2.0 times prenarial length, 2.6-3.1 in prepectoral length, 5.9-7.1 in prepelvic length; snout-vent length long, 47.4-51.1% TL; nostril 2.2-2.7% TL in width; eye-spiracle space narrow, 0.4-1.0% TL; pectoral fin medium-sized, height 8.9-13.8% TL, posterior margin 8.5-13.3% TL; anal fin tall, 3.2-4.4% TL; anal-caudal space 4.5-6.1% TL; precaudal 76-78% TL in length; interdorsal space 6.5-8.6% TL; teeth have 3-5 cusps; unicuspidate or weakly tricuspidate flank denticles; back with no greatly enlarged denticles; adult clasper long, outer length about 7% TL, well short of anal fin, interspace about 1.9% TL; vertebral centra 111-115; tooth count relatively high, 69-97 teeth in each jaw; color of upper half of body pale, with a strongly variegated pattern that is well-demarcated from the ventral surface; dark saddles (8) evident on body and caudal fin; pale variegated dorsal fins; dark blotch over gills absent; distinct V-shaped marking on posterior margin of terminal lobe of caudal fin absent; upper surfaces of pectoral and pelvic-fin without a dark central blotch; without dark saddle extending onto caudal peduncle above origin of ventral lobe of caudal fin; uniformly pale on the ventral surface; color of juveniles pale, with dark lines and spots forming rosettes and linear saddle markings, and the markings between spiracles separated into two unconnected pseudo-ocelli (Ref. 76946).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00324 (0.00157 - 0.00666), b=3.11 (2.93 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.1   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (50 of 100) .
