Rhinoptera marginata (Saint-Hilaire, 1817) | |
Rhinoptera marginata, the Lusitanian cownose ray, is a species of ray found along the western coast of Africa and Mediterranean Sea. It is apparently rare in the Mediterranean Sea, but is common in shallow waters off the western Africa. [2]
In February 2024, the species was added to the appendices of the Convention on the Conservation of Migratory Species of Wild Animals, with the species added to Appendix II, and the Mediterranean Sea population of the same species added to Appendix I.
Its maximum width is 2 m (6.6 ft). [3]
It is found in the eastern Atlantic from Portugal to the Central African coast [1] and in the eastern part of the Mediterranean Sea. [4]
They exhibit ovoviviparity (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.
The pygmy right whale is a species of baleen whale. It may be a member of the cetotheres, a family of baleen whales which until 2012 were thought to be extinct; C. marginata has otherwise been considered the sole member of the family Neobalaenidae and is the only member of the genus Caperea. First described by John Edward Gray in 1846, it is the smallest of the baleen whales, ranging between 6 and 6.5 metres in length and 3,000 and 3,500 kilograms in mass. Despite its name, the pygmy right whale may have more in common with the gray whale and rorquals than the bowhead and right whales.
The yellow-legged gull is a large gull found in Europe, the Middle East and North Africa, which has only recently achieved wide recognition as a distinct species. It was formerly treated as a subspecies of either the Caspian gull L. cachinnans, or more broadly as a subspecies of the herring gull L. argentatus. The genus name is from Latin Larus which appears to have referred to a gull or other large seabird, and the species name honours the German zoologist Karl Michahelles.
The harbour porpoise is one of eight extant species of porpoise. It is one of the smallest species of cetacean. As its name implies, it stays close to coastal areas or river estuaries, and as such, is the most familiar porpoise to whale watchers. This porpoise often ventures up rivers, and has been seen hundreds of kilometres from the sea. The harbour porpoise may be polytypic, with geographically distinct populations representing distinct races: P. p. phocoena in the North Atlantic and West Africa, P. p. relicta in the Black Sea and Sea of Azov, an unnamed population in the northwestern Pacific and P. p. vomerina in the northeastern Pacific.
The cownose ray is a species of Batoidea found throughout a large part of the western Atlantic and Caribbean, from New England to southern Brazil. These rays also belong to the order Myliobatiformes, a group that is shared by bat rays, manta rays, and eagle rays.
The Atlantic horse mackerel, also known as the European horse mackerel or common scad, is a species of jack mackerel in the family Carangidae, which includes the jacks, pompanos and trevallies. It is found in the eastern Atlantic Ocean off Europe and Africa and into the south-eastern Indian Ocean. It is an important species in commercial fisheries and is listed as a Vulnerable species on The IUCN Red List of Threatened Species.
Aetomylaeus bovinus, also known as the bull ray, duckbill ray, or duckbill eagle ray, is a species of large stingray of the family Myliobatidae found around the coasts of Europe and Africa.
The comber is a species of marine ray-finned fish from the family Serranidae, the sea basses. It is widely distributed in the eastern North and South Atlantic Oceans and into the southwestern Indian Ocean. It is caught for food and fishmeal in some parts of its range.
Mullus barbatus is a species of goatfish found in the Mediterranean Sea, Sea of Marmara, the Black Sea and the eastern North Atlantic Ocean, where its range extends from Scandinavia to Senegal. They are fished, mostly by trawling, with the flesh being well regarded. The International Union for Conservation of Nature has assessed their conservation status as being of "least concern".
The golden cownose ray or Pacific cownose ray is a species of ray. It is found in the East Pacific along the coast of Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, and Peru. Its natural habitats are open seas, shallow seas, subtidal aquatic beds, estuarine waters, intertidal marshes, and coastal saline lagoons. They are often in schools, and sometimes associated with the spotted eagle ray.
The bottlenose skate, spearnose skate, or white skate is a species of skate in the family Rajidae. It is a benthic fish native to the coastal eastern Atlantic Ocean. Due to overfishing, it has been depleted or extirpated in many parts of its former range in the northeastern Atlantic and the Mediterranean Sea, and is now endangered.
The spiny butterfly ray or giant butterfly ray is a species of butterfly ray, family Gymnuridae, native to the shallow coastal waters of the Atlantic Ocean. A large ray that can measure over 2 m across, it may be distinguished from the sympatric smooth butterfly ray by the spine at the base of its tail and by a small tentacular structure on the margin of each spiracle. Slow-reproducing and valued for its meat, in recent decades its population has experienced a decline of over 30%, and it has become Critically Endangered in certain parts of its range.
The common guitarfish is a species of cartilaginous fish in the family Rhinobatidae. It is native to the eastern Atlantic Ocean and the Mediterranean Sea. It is a bottom-dwelling fish feeding on crustaceans, other invertebrates and fish. The females give birth to live young. Its lifestyle makes it vulnerable to trawling and other fishing methods, populations seem to be declining and it has disappeared from parts of its range.
The black scorpionfish, also known as the European scorpionfish or small-scaled scorpionfish, is a venomous scorpionfish, common in marine subtropical waters. It is widespread in the Eastern Atlantic Ocean from the British Isles to the Azores and Canary Islands, near the coasts of Morocco, in the Mediterranean Sea and the Black Sea.
The streaked gurnard, also known as the African gurnard or rock gurnard, is a species of ray-finned fish belonging to the family Triglidae, the gurnards and sea robins. This fish is found in the eastern Atlantic Ocean and western Indian Ocean. This species is of commercial importance as a food fish.
The Norwegian skate, or black skate, is a species of skate found at depths of 200 m (660 ft) to over 1,600 m (5,200 ft) in the East Atlantic region. Initially its range was believed to be restricted to the Norwegian Sea and North Sea to the Bay of Biscay. It is occasionally encountered off the western coast of Ireland, and historically has been found near Rockall and in the Norwegian Deep, though recent surveys have not identified the species there. The species has frequently been confused with other skates, and since the late 1980s it has been confirmed to occur more widely, ranging from Iceland to Morocco, as well as off South Africa and in the Mediterranean Sea.
The sand steenbras or striped seabream is a species of marine fish in the family Sparidae. It is found in shallow water in the Mediterranean Sea and in the eastern Atlantic Ocean from France to South Africa. It also occurs in the Red Sea and off the coast of Mozambique in the Indian Ocean. The IUCN has assessed its conservation status as being of "least concern".
The common eagle ray or bullray is a species of fish in the family Myliobatidae. It inhabits the eastern Atlantic Ocean, the Mediterranean Sea and the south-western Indian Ocean.
Apogonichthyoides pharaonis, the Pharaoh cardinalfish, is a species of cardinalfish from the family Apogonidae which is found the western Indian Ocean and Red Sea. It is one of a group of species which have colonised the eastern Mediterranean Sea from the Red Sea via the Suez Canal, a process known as Lessepsian migration.
The African striped grunt is a species of marine ray-finned fish, a sweetlips belonging to the subfamily Plectorhinchinae, one of two subfamilies in the family Haemulidae, the grunts. It is found in the eastern Atlantic Ocean.
