Environment: milieu / climate zone / depth range / distribution range
生态学
海洋 居于水底的; 深度上下限 ? - 300 m (Ref. 4426). 亞熱帶的; 46°N - 30°N, 8°W - 36°E
Eastern Atlantic: known only from the Mediterranean but may penetrate through the Strait of Gibraltar and possibly to northern Morocco. Some Atlantic records probably misidentifications of Raja naevus and/or Raja africana.
東大西洋: 已知只來自了地中海但是可能貫透經過直布羅陀海峽與可能地到摩洛哥北部。 一些大西洋的記錄可能是 雜斑鰩〔Raja naevus〕 及[或] 非洲鰩〔Raja africana〕 的誤鑑。

Max length : 70.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 4426)
Range from coastal waters to about 300 m depth (Ref. 3167). Feed on all kinds of bottom animals (Ref. 3167). Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). About 80-154 eggs are laid by an individual in a year (Ref. 41305).
范围从沿岸水域到大约 300 公尺深.(参考文献 3167) 捕食各种的底部动物。 (参考文献 3167) 卵生的。 明显的成对出现。 幼鱼可能倾向跟随大的个体, 例如他们的母亲.(参考文献 205) 卵为长方形鞘囊具有僵硬的触角沈积在沙滩或泥滩的角落.(参考文献 205) 大约 80-154个卵在一年中被一个个体生产。 (参考文献 41305)
Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔鱼
Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Spawns throughout the year with maximum number of egg-cases laid in late spring and summer, embryos developing in about 4 months (Ref. 3167). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).東大西洋: 已知只來自了地中海但是可能貫透經過直布羅陀海峽與可能地到摩洛哥北部。 一些大西洋的記錄可能是 雜斑鰩〔Raja naevus〕 及[或] 非洲鰩〔Raja africana〕 的誤鑑。
