Anacanthobatidae (Smooth skates)
Etymology: Anacanthobatis: Greek, ana = up + Greek, akantha = thorn + Greek, batis, -idos = a ray (Ref. 45335).

生态学
海洋 深海底的; 深度上下限 230 - 322 m (Ref. 5578). 深水域; 24°S - 30°S, 29°E - 40°E (Ref. 57365)
Western Indian Ocean: known only from southern Mozambique to Durban, South Africa.

大小 / 重量 / 年龄
成熟度: Lm ?  range ? - ? cm
Max length : 29.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 95335)
背棘 (总数) : 0. A brown-spotted legskate with smooth skin and a short slender tail less than body length; snout angular with tiny filament; pectoral disc with rounded corners; no large thorns on denticles except for alar spines on adult males (Ref. 5578). Legskates have pelvic fins separated into a mobile leg-like front lobe, and a rear lobe that may be fused to the tail base (Ref. 5578). Mottled brown and white with scattered ocelli dorsally; uniform pale ventrally (Ref. 6510). Papillae and rostral filament dark brown (Ref. 6510).
Body shape (shape guide): other.
一有褐色斑点的 魮有平滑的皮肤与短的细长尾部少于体长; 吻有角的有极小的丝状突起; 用圆角的胸盘; 没有在细齿上的大的刺在雄性成鱼上除了翼的棘。 (参考文献 5578) 魮有分开成移动的腿状前叶的腹鳍 , 与可能融合成尾部基底的一个后面的叶。 (参考文献 5578) 褐色班点的而且背面白色的有分散的假眼斑; 全灰白色的腹地.(参考文献 6510) 乳突与嘴的丝状突起深褐色的.(参考文献 6510)
Possibly the smallest southern African skate (Ref. 5578). Found on the upper slope (Ref. 5578).
可能最小的非洲南部溜冰。 (参考文献 5578) 栖息于上层斜坡了。 (参考文献 5578)
