Philippines country information

Common names: [No common name]
Occurrence: native
Salinity: marine
Abundance: occasional (usually not seen) | Ref:
Importance: subsistence fisheries | Ref:
Aquaculture: | Ref:
Regulations: | Ref:
Uses: live export: yes;
Comments: A single specimen (CAS 29409, 66.1 mm SL) from the Philippines has relatively long pectoral fins (length 75.1 % of SL), the posterior tip of which extending slightly beyond vertical through the caudal-fin base. This is in contrast, with typical specimens of D. brachypterus which possess relatively short pectoral fin (length 47.0-67.8 % of SL) and the posterior tip not reaching the caudal-fin base. However, because there are no other noticeable differences found between this specimen and typical D. brachypterus, the former is regarded as aberrant (Ref. 116325). Also Ref. 1602, 2334, 90102.

生物學特性     字彙 (例如 epibenthic)

Common in reef flats and shallow lagoons, in areas with weed-covered rocks on sandy substrates. Adults often found on sponges and juveniles are sometimes found in small aggregations on remote bommies with 10 or so individuals (Ref. 48635). Nocturnal. Feeds on small crustaceans (Ref. 37816).

常見於礁石平臺與潟湖淺灘,在沙的底部上在有雜草覆蓋的岩石的區域中。 成魚時常發現於海綿而且稚魚有時候發現於小群魚群在遙遠的 bommies 上和 10 左右的個體.(參考文獻 48635) 夜行的。 吃小型甲殼動物。 (參考文獻 37816)
