A tuna is a saltwater fish that belongs to the tribe Thunnini, a subgrouping of the Scombridae (mackerel) family. The Thunnini comprise 15 species across five genera, the sizes of which vary greatly, ranging from the bullet tuna up to the Atlantic bluefin tuna, which averages 2 m (6.6 ft) and is believed to live up to 50 years.
Mackerel is a common name applied to a number of different species of pelagic fish, mostly from the family Scombridae. They are found in both temperate and tropical seas, mostly living along the coast or offshore in the oceanic environment.
The turbot is a relatively large species of flatfish in the family Scophthalmidae. It is a demersal fish native to marine or brackish waters of the Northeast Atlantic, Baltic Sea and the Mediterranean Sea. It is an important food fish. Turbot in the Black Sea have often been included in this species, but are now generally regarded as separate, the Black Sea turbot or kalkan. True turbot are not found in the Northwest Atlantic; the "turbot" of that region, which was involved in the so-called "Turbot War" between Canada and Spain, is the Greenland halibut or Greenland turbot.
The knifetooth dogfish, is a harmless sleeper shark of the family Somniosidae, found in the eastern Atlantic, from Scotland to Spain, Portugal, and Senegal, and the southwest Pacific from New Zealand, between latitudes 58°N and 15°N, at depths of between 200 and 1,600 m. Its length is up to 1.1 metres (3.6 ft).
Anaecypris hispanica, the Spanish minnowcarp, is a small species of ray-finned fish species in the family Cyprinidae. It is the only living member of the genus Anaecypris. It is endemic to the Iberian Peninsula and is found in the basin of the Guadiana River in southern Spain and Portugal. Its natural habitats are rivers and intermittent rivers which are shallow, highly oxygenated, have a water temperature of no more than 25 °C and have a coarse stream bed. It is threatened by habitat loss. They grow to a maximum size of 60mm and live for three years.
Luciobarbus steindachneri is a species of cyprinid fish. It is here placed in Luciobarbus following the IUCN, but that genus is very closely related to the other typical barbels and perhaps better considered a mere subgenus of Barbus.
Chondrostoma is a genus of ray-finned fish in the family Cyprinidae. They are commonly known as nases, although this term is also used locally to denote particular species, most frequently the common nase . The common name refers to the protruding upper jaw of these fishes; it is derived from the German term Nase 'nose'.
Iberochondrostoma oretanum is a species of cyprinid fish endemic to Spain where it is found in the Robledillo and Fresnada rivers, tributaries of the Jándula in the Guadalquivir system.
Iberochondrostoma lusitanicum, or the boga-portuguesa, is a species of freshwater fish in the family Cyprinidae. It is found only in a very restricted area in Portugal, and is threatened by pollution and habitat destruction (dams).
Squalius carolitertii, the Northern Iberian chub, is a species of fresh-water fish in the family Cyprinidae. It is found in Portugal and Spain, and known there as the bordallo, escalo or gallego.
The Mediterranean, Southern or Miller's water shrew is a species of insectivoran mammal in the family Soricidae.
The freshwater blenny is a species of fish in the family Blenniidae. It is found in African rivers and brooks in Algeria and Morocco flowing to the Mediterranean Sea. In Europe it is widespread in the freshwaters of Albania, Croatia, France, Greece, Italy, Montenegro, Spain and Portugal, while in Asia it is in Turkey and Israel. This species reaches a length of 15 centimetres (5.9 in) TL. This taxon may be paraphyletic as the populations in Turkey and Israel are more genetically divergent from other populations of freshwater blenny than the Trichonis blenny, and the population in Kinneret Lake in Israel has been proposed as a new species.
The narrow-barred Spanish mackerel is a mackerel of the family Scombridae found in a wide-ranging area in Southeast Asia, but as far west as the east coast of Africa and from the Middle East and along the northern coastal areas of the Indian Ocean, and as far east as the South West Pacific Ocean.
An anchovy is a small, common forage fish of the family Engraulidae. Most species are found in marine waters, but several will enter brackish water, and some in South America are restricted to fresh water.
Achondrostoma is a genus of freshwater fish in the family Cyprinidae, the carps and minnows. It is endemic to the Iberian Peninsula.
Iberochondrostoma almacai is a species of cyprinid fish endemic to southern Portugal, where it is only found in the drainages of the Mira, Arade and Bensafrim rivers. It shelters in pools when the rivers shrink in the summer and is threatened by habitat destruction caused by water abstraction and predation and competition from introduced species of fish such as Gambusia, Micropterus and Lepomis.
Iberochondrostoma olisiponensis, the Lisbon arched-mouth nase, is a freshwater fish discovered in 2007 in the lower Rio Tejo basin, Portugal.
Pomatoschistus lozanoi, Lozano's goby, is a species of goby native to the northeastern Atlantic Ocean from the North Sea to northwestern Spain and Portugal where it can be found at depths of from 70 to 80 metres. This species can reach a length of 8 centimetres (3.1 in) TL and is known to live for only two years. The specific name honours the Spanish zoologist Luis Lozano Rey (1878-1958).
