Eponymy: The original description has no etymology but, though the binomial looks as if it could be an eponym, it is merely a translation: aka is Japanese for red, referring to its bright orange-red underside and jei is Japanese for ray/skate. (Ref. 128868), visit book page.

Disc rhomboid, anterior margin straight, posterior margin convex. Snout triangular and slightly produced. dorsal keel present on tail. Adults with small spines on disc and posterior part of tail. Brown dorsally and some with orangish pectoral fin margins, in front of eyes, behind spiracles, on the sides of the tail just anterior to the sting. Ventrum orangish red.
Body shape (shape guide): other.
体盘偏菱形，前缘直线, 后缘凸状。 吻三角形的而且些微地生产。 背部的龙骨脊位于尾部之上。 在体盘与尾部的较后面的部分上成鱼有小的棘。 背部褐色的而且一些具有在呼吸孔后面的在眼睛前面的橘色胸鳍边缘, 在尾部侧边上正好位于刺前。 Ventrum 橘红色。
Found in coral reefs and estuarine areas, on sand and mud bottoms (Ref. 12951, 11230). Feeds on small fishes and crustaceans (Ref. 9840). Ovoviviparous with litters of only 1 pup (Ref. 114953) while earlier estimates indicated production of up to 10 in a litter (Ref. 12951). Caught occasionally by bottom trawl fisheries operating inshore. Utilized for its meat but of limited value due to its small size (Ref.58048). Served in 'miso' soup, hard boiled with seasonings, or for 'kamaboko' material (Ref. 637).
在沙与泥底部上, 发现于珊瑚礁与河口地区了。 (参考文献 12951,11230) 吃小鱼与甲壳动物。 (参考文献 9840) 卵胎生的多达 10 一胎.(参考文献 12951) 以 'miso' 汤供应了,与调味料确实煮沸, 否则对于 'kamaboko' 材料.(参考文献 637)

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). Distinct pairing with embrace (Ref. 205).西太平洋: 日本南部到泰國。 也已知來自斐濟與吐瓦魯。 (參考文獻 12596)
