> Gobiesociformes (Clingfishes) > Gobiesocidae (Clingfishes and singleslits) > Protogobiesocinae
Etymology: Protogobiesox: ‘‘ancestral gobiesocid;’’ it refers to the pelvic fins resembling the putative ancestral form of gobiesocids.; asymmetricus: Named for the unusual asymmetry of head and body..

Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt): 9-10; Afterflossenweichstrahlen: 8; Wirbelzahl: 34 - 35. Dorsal-fin rays 9-10; anal-fin rays 8; pectoral-fin rays 17-24; principal caudal-fin rays15, gills3, the third arch with 3 gill rakers; total vertebrae 34-35, with asymmetrical lateral bending starting behind the skull, bent at an angle of 85°-92°; asymmetrical skull in frontal view; naked skin, surface of head and body without striae; disc without adhesive papillae; posterior margin may be partially fringed; region B small, left- and right-hand sides separate, larger on the right-hand side than on left-hand side (Ref. 117884).

Found in relatively cool water in an area with temporary upwelling along the northern coast of Papua New Guinea and in association with sunken logs; its specializations and especially the lateral asymmetry may be useful to be attached to these logs (Ref. 117884).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.3 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
