Etymology: Hypseleotris: Greek, hypselos = high + The name of a Nile fish, eleotris (Ref. 45335);  gymnocephala: Name from the Greek words 'gymnos' meaning naked, and 'kephale', Latinized to 'cephalus' meaning head; in reference to the scaleless skin of the forehead, nape and dorsal midline anterior to the 1st dorsal fin (Ref. 128732).

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 8 - 9; Dorsal soft rays (total): 11 - 12; Anal spines: 1; Anal soft rays: 11 - 12; Vertebrae: 30 - 31. This species is distinguished from other southeastern Hypseleotris by the following set of characters: blunt head and lack of dorsal scales up until posteriad as middle of second dorsal fin; absence of pointed median fin tips (present in H. acropinna, H. galii, H. mooloboolaensis); and distinct median fin coloration in mature males: distal portion of fin bearing band of pale orange, shading into thin band of white (Ref. 128732).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = No PD50 data   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00260 - 0.01111), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.2 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.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
