Actinopteri (ray-finned fishes) > Gobiiformes
(Gobies) > Oxudercidae
(Mudskippers) > Periophthalminae
Etymology: Periophthalmus: Greek, peri = around + Greek, ophthalmos = eye (Ref. 45335); novaeguineaensis: Named for Edward Murdy, in appreciation of his considerable work on mudskipper taxonomy and relationships.

(total): 10 - 15;
soft rays: 10 - 11. This species is distinguished by the following characters: D1 modally XI; D2 modally I,12; A modally I,11; caudal fin modally with 17 segmented rays; 71-110 lateral scales; 25-32 predorsal scales; inner rays of pelvic fin always united for more than three-quarters of their length; color of first dorsal fin red-brown or black, with broad, black submarginal stripe and white distal margin, the posterior edge concave, giving triangular shape to fin; color of second dorsal fin with whitish margin and one broad, black sub-marginal band and basal row of black spots; anal, pectoral, or caudal fins usually no markings, small brown spots or dusky pigment along length of fin or fin rays in some individuals; pelvic fin with prominent frenum and heavily pigmented on dorsal surface, with narrow, yellowish to whitish marginal band (Ref. 83599).
An intertidal and amphibious air-breather (Ref. 31184) which inhabits brackish mangrove and nipa palm areas, sometimes enters the lower reaches of freshwater streams (Ref. 2847. 44894). Occurs in the margin of estuaries and tidal creeks (Ref. 44894). Actively shuttling back and forth between rock pools and air (Ref. 31184).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00475 - 0.02204), 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
): 3.2 ±0.4 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 (18 of 100) .
