Disk has sharp outer corners and irregular row of short spines on upper surface (Ref. 26938). Disk usually uniform dark brown above, grayer in young. Ventral finfold on tail long and high, dorsal finfold absent (Ref. 7251). Upper surface of disc gray, dark or olivaceous brown or olive green. Lower surface of disc white or whitish with an edging of gray or brown (Ref. 6902).

Found on sandy bottoms, seagrass beds, lagoons and the reef face (Ref. 12951). Common in bays and estuaries (Ref. 7251). Observed singly, in pairs and in aggregations (Ref. 12951). Buries in the sand during the day and forages at night, usually in seagrass beds (Ref. 12951). Feeds mainly on bivalves and worms and also takes shrimps, crabs and small fishes (Ref. 3168). Feeds by creating depressions in the sand to expose invertebrates and small fishes (Ref. 9710). Ovoviviparous, with 3-4 in a litter (Ref. 12951). May be found in cleaning stations where they are attended to by the bluehead wrasse and Spanish hogfish (Ref. 12951). Equipped with a well-developed serrated spine and capable of inflicting a painful laceration. Easily approached by divers (Ref. 9710).
棲息於砂質底部，海草床，潟湖與礁面了。 (參考文獻 12951) 常見於海灣與河口。 (參考文獻 7251) 各別地觀察, 成對與聚集成群.(參考文獻 12951) 埋藏在沙子中在白天期間而且覓食在晚上, 通常在海草床.(參考文獻 12951) 主要吃二枚貝與蠕蟲以及捕食蝦類，螃蟹與小魚.(參考文獻 3168) 藉由製造凹陷在砂中暴露無脊椎動物與小魚的吃.(參考文獻 9710) 卵胎生的, 有三至四個一胎.(參考文獻 12951) 可能被發現於清潔的區域在那裡它們被藍頭魚隆頭魚與西班牙的狐鯛伴隨著.(參考文獻 12951) 具有了鋸齒狀的棘一個發展良好的與能夠施放令人痛苦的撕裂。 藉著潛水者容易接近。 (參考文獻 9710)

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). Male mounts on female dorsally (Ref. 12951).西大西洋: 美國的紐澤西與墨西哥灣北部到巴西南部, 包括安地列斯群島.(參考文獻 3168)
