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.

биология     глоссарий (например epibenthic)

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).

Life cycle and mating behavior Maturities | размножение | Spawnings | Egg(s) | Fecundities | личинки

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).
