Max length : 200 cm WD 雄魚/尚未辨別雌雄; (Ref. 30573)
With distinctive color pattern and exceptionally long spineless tail over six times the length of the body (Ref. 37816).
有特殊的彩色斑紋與特別長的無棘尾部超過六倍於體長。 (參考文獻 37816)
Found inshore (Ref. 9862). Inhabits mangrove creeks and protected sandy channels to a depth of at least 18 m; relatively uncommon (Ref. 37816). Active swimmer, travelling long distances; feeds on crustaceans and molluscs (Ref. 68964). Ovoviviparous (Ref. 50449). Caught occasionally by bottom trawl, tangle net and inshore gillnet fisheries. Utilized for its meat, but of limited value as it is not frequently landed (Ref. 58048). Presumably utilized for human consumption in the western central Pacific (Ref. 9862).
發現於岸邊了。 (參考文獻 9862) 棲息於紅樹林小溪與有遮蔽的沙峽道到深度至少 18 公尺; 相當罕見.(參考文獻 37816) 卵胎生的.(參考文獻 50449) 推測為在中太平洋西部供人類消費使用。 (參考文獻 9862)
