Etymology: Boleophthalmus: Name from Greek, ßoƛɛ for ejected and 'ophthalmos' for eye; refers to species capability to rapidly raise their eyes above the level of their orbital cavities, as if the eyes were being ejected; poti: Named came from the indigenous people of the Wapi villages of Purutu Island, the specie's type locality. They call this species ‘poti’, where in their language means ‘spotted’ and refers to the
numerous tiny whitish spots present on the head of this fish.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; freshwater; brackish; pelagic-neritic. Tropical
Western Pacific: Papua New Guinea.
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 10.6 cm SL male/unsexed; (Ref. 93058); 10.8 cm SL (female)
Dorsal spines (total): 5; Dorsal soft rays (total): 23 - 26; Anal soft rays: 24 - 26. This species is similar to B. birdsongi and B. caeruleomaculatus in having unnotched, flattened and horizontally disposed dentary teeth. It differs from its congeners by having an elongate D1 fin spines, protruding from the fin margin (in both sexes) and having the following dorsal-fin colouration in live individuals: D1 with clearly demarcated sky-blue to whitish marginal band; interradial membranes of D1 greenish-brown, spotted with whitish to yellowish speckles, sometimes fused into broken, narrow and wavy lines; the interradial membranes of D2 are grey to pale brown, darker posteriorly, pale grey distally, with a very thin white margin and columns of 0-5 whitish spots between adjacent rays; and D2 rays are darker than interradial membranes (Ref. 93058).
Facultative air-breathing (Ref. 126274); Specimens were collected by hand in tidally exposed burrows, seaward to the pneumatophore zones of pioneer mangrove shores dominated by Sonneratia caseolaris, and along mud banks of intertidal creeks (Ref. 93058).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00326 - 0.01539), b=2.95 (2.76 - 3.14), 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).
