Raja, also known as raia, is a genus of skates in the family Rajidae containing 16 species. Formerly a wastebasket genus, many species historically placed here have been moved to other genera in the family, such as Amblyraja, Beringraja, Dipturus, Leucoraja and Rostroraja. Raja are flat-bodied, cartilaginous fish with a rhombic shapes due to their large pectoral fins extending from or nearly from the snouts to the bases of their tails. Their sharp snouts are produced by a cranial projection of rostral cartilage. The mouth and gills are located on underside of the body. They may be either solid-coloured or patterned, and most skates have spiny or thorn-like structures on the upper surface, and some species contain weak electrical organs within their tails. Mating typically occurs in the spr

  • Raja, also known as raia, is a genus of skates in the family Rajidae containing 16 species. Formerly a wastebasket genus, many species historically placed here have been moved to other genera in the family, such as Amblyraja, Beringraja, Dipturus, Leucoraja and Rostroraja. Raja are flat-bodied, cartilaginous fish with a rhombic shapes due to their large pectoral fins extending from or nearly from the snouts to the bases of their tails. Their sharp snouts are produced by a cranial projection of rostral cartilage. The mouth and gills are located on underside of the body. They may be either solid-coloured or patterned, and most skates have spiny or thorn-like structures on the upper surface, and some species contain weak electrical organs within their tails. Mating typically occurs in the spring and the female lays numerous eggs per clutch which are encapsulated in leathery cases, commonly known as "mermaid’s purses". Species vary in size, ranging from about 40 to 140 cm (1.3–4.6 ft) in length. These bottom-dwellers are active during both day and night, and typically feed on molluscs, crustaceans and fish. Raja skates are found in the East Atlantic, including the Mediterranean, and western Indian Ocean, ranging from relatively shallow water to a depth of 800 m (2,600 ft). Skates and related species have fossil records dating from the Upper Cretaceous period, thus this well-adapted species is quite ancient. (en)

  • Raja é um dos géneros de raias pertencente à família dos rajídeos. São peixes cartilaginosos achatados com uma forma rômbica devido às suas grandes barbatanas peitorais que se estende desde ou quase do focinho até a base da sua cauda. Seus focinhos são acentuados por uma projeção cranial da cartilagem rostral. A boca e as brânquias localizadas na parte inferior do corpo. Podem ter cores sólidas ou padrões, e têm estruturas espinhosas na superfície superior, e algumas espécies contêm órgãos elétricos dentro de suas caudas. O acasalamento ocorre normalmente na primavera e a fêmea bota e desova numerosos ovos. Espécies variam em tamanho: A raia-de-verão (R. erinacea) mede até 50 cm de comprimento e a raia-gigante (R. binoculata) mede até 2,5 m de comprimento. Raja estão ativas durante o dia ea noite e normalmente se alimentam de moluscos, crustáceos e peixes. São encontrados em muitas partes do mundo, de tropical até perto de águas árticas, desde águas rasas até profundidades de mais de 2.700 metros. Têm registros fósseis que datam no período Cretáceo Superior, portanto, esta espécie bem adaptada é bastante antiga. (pt)
  • Ромбовые скаты (лат. Raja) — род скатов одноимённого семейства отряда скатообразных. Это хрящевые рыбы, ведущие донный образ жизни, с крупными, уплощёнными грудными плавниками в форме ромба и выступающим рылом. На вентральной стороне диска расположены 5 жаберных щелей, ноздри и рот. Диск всегда длиннее хвоста. Рыло плотное, негибкое. Максимальная длина 180 см. Эти скаты обитают в Атлантическом, Тихом и Индийском океане. В основном глубоководные виды, встречаются на глубине до 1600 м. Размножаются, откладывая яйца, заключённые в прочную роговую капсулу с выступами по углам. Название рода происходит от лат. raja — «хвостокол». (ru)
