Short description
Identification keys | Morphology | Morphometrics
Diagnosis: This species of the Prooculis group has a body without alternating dark and pale stripes or distinct dark spots; there is a dark stripe extending posteriorly from orbital margin across head and variably for short distance onto body anteriorly. In life, the dark post-orbital stripe is bordered ventrally by bright white stripe; other bright markings on head, white with at most a very faint tinge of yellow; belly bluish (Ref. 54476).
This is one of the smallest species of Ecsenius, female at 2.37 cm SL having well-developed, apparently ripe, ovaries. The 1.56 cm SL male has well-developed dentary teeth, including obvious posterior canines; where in most Ecsenius species, at this size, the posterior canines are not present and the number of other dentary teeth does not appear to have been completely established (Ref. 54476). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00461 - 0.02381), b=2.98 (2.79 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
