توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل) : 6 - 7; شعاع نرم باله پشتي (کل) : 9; خارهاي باله مخرجي: 1; شعاع نرم باله مخرجي: 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).
Body shape (shape guide): elongated.
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).
