Short description Morphology | Morphometrics

Dorsal spines (total): 5 - 7; Dorsal soft rays (total): 10-12; Anal spines: 1; Anal soft rays: 11 - 13. Can be distinguished by the following characters: body depth at anal fin origin 10.6-14.6% of SL, mean 12.7%; unique among Periophthalmus species in having a greatly reduced first dorsal fin (depressed dorsal 5.1-9.6% of SL) in both sexes, and usually with only five spines, fin widely separated from second dorsal fin origin; pelvic fins united for half their length, distinct fraenum present, posterior tips of fins pointed to bluntly pointed, fifth ray bifurcating close to base and branching about 9 times; first dorsal fin plain blackish except for slightly paler base and narrow whitish margin; second dorsal fin translucent with broad submarginal black band and a row of black spots or blotches along fin base; no melanophores on anal fin; pelvic fins whitish or with some fine speckling; orange spots may be present on lower side of head and body when live; second dorsal fin rays modally I,11; anal fin rays modally I,12; pectoral rays 11-13; caudal fin rays usually only with ventralmost 6-7 rays branched, dorsalmost 8-9 rays rarely branched; lateral scales 58-78; predorsal scales usually 24-25 (Ref. 76839).

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=0.01023 (0.00484 - 0.02165), b=2.99 (2.81 - 3.17), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.1   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (11 of 100) .
