Short description Identification keys | Morphology | Morphometrics
Dorsal spines (total): 6 - 7; Dorsal soft rays (total): 9; Anal spines: 1; Anal soft rays: 10. Stiphodon palawanensis is distinguished by the following characters: first dorsal fin pointed in male; second dorsal fin usually with one spine and nine segmented rays, pectoral fin usually with 15 segmented rays; relatively large caudal fin (26-34% of SL) in male; premaxilla with 45-71 tricuspid teeth, dentary with 2-6 (male) or 1-4 (female) symphyseal teeth and 45-79 unicuspid horizontal teeth; nape and posterior part of occipital region covered by cycloid scales; 9-11 dusky transverse bars laterally on trunk and tail; first dorsal fin gray or dusky after preservation (orange or reddish brown in life) without any distinct markings, having a line of black blotches (male) or a black band (female) on distal part of second dorsal fin; pectoral fin without clear markings (Ref. 104909).
Occurs in pools with a substrate composed of a mixture of boulders, gravel, and pebbles with exposed bedrock in some places. Also found in rapids. Two cyprinid species, Barbodes palavanensis (Boulenger) and Rasbora everetti Boulenger co-exist very abundantly with Stiphodon palawanensis. Syntopic with other common fishes such as two gobioids, Glossogobius illimis Hoese & Allen and Redigobius sp., and a halfbeak Dermogenys palawanensis Meisner (Ref. 104909).

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5000 [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).
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).
