IngliżDiagnosis: 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).
Description: A very large stingray; disc rhombic, the anterior margins forming a blunt angle (Ref. 6902, 39859, 81259). Dorsal surface entirely, but irregularly rough, with a mid-dorsal row of large thorny tubercles provided with striate bases and erect cusps; a few similar tubercles scattered over pectoral fins and head (Ref. 81259). Tail whip-like and strongly spinous, with numerous rows of small spines; tail with a short dorsal ridge behind the sting and a poorly developed ventral fold, which is long long, but quite low and not easily seen (Ref. 7251).
Colouration: Dorsal side dark brown to olivaceous-brown; the lower surface whitish, with or without dark pectoral margins; tail blackish behind the sting (Ref. 6902, 81259).

MaltiDjanjosi: Kampjuni kbar ta ' Dasyatis centroura huma rikonoxxibbli bid-dnub thorny tagħhom, mill-kbir daqs u spazjar ta ' l-ispazjar wiesgħa tal-bucklers nofs dorsali tagħhom, u mill-tubercles konspikwi jew bucklers fuq il-Partijiet fuq barra ta ' diski tagħhom; f'tipi iżgħar-tubercles kbar ma għadu żviluppaw fuq id-denb (Ref. 6902). Tkun differenti minn Dasyatis sabina, D. guttata u Himantura schmardae fil-għamla ta ' diska; li tixbaħ jgħidu li Dasyatis u jiġu D. fil-forma ta ' diska, imma li jistgħu jiġu distinti minn D. jiġifieri mill-fatt li d-denb m ' għandhiex kull traċċa tal-tinja kutaneju hawn fuq, u minn jiġu D. permezz tiegħu ħafna aktar dejqa bridges tailfold (Ref. 6902).
Deskrizzjoni: A stingray kbar ħafna; id-diska rhombic, il-marġini anterjuri li jiffurmaw a angolu ċatt (Ref. 6902, 39859, 81259). Wiċċ dorsali għal kollox, imma irregolarment aħrax, ma filliera nofs dorsali tal-tubercles kbar thorny mogħnija striate bażijiet u bini ta ' cusps; ftit tubercles simili imferrex fuq mhux xewk u ras (Ref. 81259). Denb whip simili u spinous bil-qawwi, b ' fillieri numerużi ta ' spines żgħar; denb mal-ridge dorsali qasir wara il-Commemorative u tinja bridges ma tantx żviluppati, li hija twila twila, imma pjuttost baxx u mhux faċilment jara (Ref. 7251).
Kolorazzjoni: Ġenb dorsali kannella skur għal kannella olivaceous; il-wiċċ t'isfel abjad, bi jew mingħajr il-marġini pettorali fid-dlam; denb iswed lura il-Commemorative (Ref. 6902, 81259).
