简单描述 型态特徵 | 形态测量图

With distinctive color pattern and exceptionally long spineless tail over six times the length of the body (Ref. 37816).
有特殊的彩色斑纹与特别长的无棘尾部超过六倍于体长。 (参考文献 37816)

生物学特性     字汇 (例如 epibenthic)

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).

发现于岸边了。 (参考文献 9862) 栖息于红树林小溪与有遮蔽的沙峡道到深度至少 18 公尺; 相当罕见.(参考文献 37816) 卵胎生的.(参考文献 50449) 推测为在中太平洋西部供人类消费使用。 (参考文献 9862)

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449).印度-西太平洋: 印度到中國與印尼。
