简单描述 型态特徵 | 形态测量图

Diagnosis: Large specimens of Dasyatis centroura are recognizable by their thorny tails, by the large size and wide spacing spacing of their mid-dorsal bucklers, and by the conspicuous tubercles or bucklers on the outer parts of their discs; in smaller specimens the large tubercles have not yet developed on the tail (Ref. 6902). It differs from Dasyatis sabina, D. guttata and Himantura schmardae in the shape of disc; it resembles Dasyatis say and D. americana in shape of disc, but it can be distinguished from D. say by the fact that the tail lacks any trace of a cutaneous fold above, and from D. americana by its much narrower ventral tailfold (Ref. 6902).
体盘接近四边形的有强弯曲的前边缘,钝的吻.(参考文献 39859) 巨大的体型与背部中央圆盾的空隙, 在体盘的外部部份上的显着的小瘤.(参考文献 6902) 尾部有很多的列小的棘。 腹面鳍褶长的, 但是相当低不被容易地见到, 背部的鳍褶不存在.(参考文献 7251) 背面黄褐色的, 腹面白色或几乎白的。 下表面白色的而且没有深色的边缘.(参考文献 6902)

生物学特性     字汇 (例如 epibenthic)

Dasyatis centroura is a coastal species (Ref. 81259), found over sandy and muddy bottoms (Ref. 3169). It feeds on bottom-living invertebrates and fishes (Ref. 3169). Ovoviviparous (Ref. 6901). Wings marketed fresh, smoked, dried-salted; used for fishmeal and oil. Harmful to shellfish banks; dangerous to bathers and fishers due to its poisonous spine. May attain well over 100 cm TL. Warm season visitor to coastal waters (Ref. 6902).

Life cycle and mating behavior 成熟度 | 繁殖 | 产卵场 | | 孕卵数 | 仔鱼

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). Gestation about 4 months with 2 to 4 young produced in autumn and early winter (Ref. 6901). Distinct pairing with embrace (Ref. 205).東大西洋: 比斯開灣南部到安哥拉,包括地中海,馬得拉群島與加納利群島。 西大西洋: 新英格蘭喬治亞淺灘到墨西哥灣東部; 巴西南部到烏拉圭。
