Short description Morphology | Morphometrics

A species of Elacatinus with dorsal-fin elements VII, 11 (rare 10); anal-fin elements 10 (uncommon 9); pectoral-fin rays 20 (20–22); pelvic fins fully-joined, short cup-like disk complete; no scales; a pale head with a prominent red stripe from the tip of the snout across the eye ending abruptly above the pectoral-fin base with a short orange segment, followed by a short black segment; notably with an additional red stripe across the cheek from the corner of the jaw to the mid-pectoral-fin base; a dark green body with 23–26 thin light green bars along the full length of the body (Ref. 84089).

Estimates based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00589 (0.00267 - 0.01297), b=3.10 (2.91 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.0 ±0.3 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.).

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