簡短描述
型態特徵 | 形態測量圖
A legskate with a pointed thornless snout and with large whitish thorns on shoulders, around the eyes, and in a single row from the nape to the 1st dorsal fin (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). Uniformly reddish-brown above, lighter below (Ref. 5578).
