European pilchard
The European pilchard ("Sardina pilchardus") is a species of ray-finned fish in the monotypic genus Sardina. The young of the species are among the many fish that are sometimes called sardines. This common species is found in the northeast Atlantic, the Mediterranean, and the Black Sea at depths of . It reaches up to in length and mostly feeds on planktonic crustaceans. This schooling species is a batch spawner where each female lays 50,000–60,000 eggs.

Maria River (Australia)
Maria River, a watercourse of the Hastings River catchment, is located in the Mid North Coast region of New South Wales, Australia.
Portugal
There are more than 100 freshwater fish species, varying from the giant European catfish (in the Tagus International Natural Park) to some small and endemic species that live only in small lakes (along the western portion of country, for example). Some of these rare and specific species are highly endangered because of habitat loss, pollution and drought. Up-welling along the west coast of Portugal makes the sea extremely rich in nutrients and diverse species of marine fish; the Portuguese marine waters are one of the richest in the world. Marine fish species are more common, and include thousands of species, such as the sardine (Sardina pilchardus), tuna and Atlantic mackerel. Bioluminescent species are also well represented (including species in different colour spectrum and forms), like the glowing plankton that are possible to observe in some beaches.
Amazon rainforest
The region is home to about 2.5 million insect species, tens of thousands of plants, and some 2,000 birds and mammals. To date, at least 40,000 plant species, 2,200 fishes, 1,294 birds, 427 mammals, 428 amphibians, and 378 reptiles have been scientifically classified in the region. One in five of all the bird species in the world live in the rainforests of the Amazon, and one in five of the fish species live in Amazonian rivers and streams. Scientists have described between 96,660 and 128,843 invertebrate species in Brazil alone.
Ripple River
The Ripple River is a small river that starts at the outlet of Bay Lake of Crow Wing County, Minnesota, and ends in Aitkin, the county seat of Aitkin County, at its confluence with the Mississippi River. The river follows a circuitous route: as the crow flies, the distance between its source and mouth is , but the total stream length is .
Marañón River
The Marañón River (, ) is the principal or mainstem source of the Amazon River, arising about 160 km to the northeast of Lima, Peru, and flowing through a deeply eroded Andean valley in a northwesterly direction, along the eastern base of the Cordillera of the Andes, as far as 5° 36′ southern latitude; from where it makes a great bend to the northeast, and cuts through the jungle Andes, until at the Pongo de Manseriche it flows into the flat Amazon basin. Although historically, the term "Marañon River" often was applied to the river all the way to the Atlantic Ocean, nowadays the Marañon River is generally thought to end at the confluence with the Ucayali River, after which most cartographers label the ensuing waterway the Amazon River.
Danube
The Danube was once a long - standing frontier of the Roman Empire, and today flows through 10 countries, more than any other river in the world. Originating in Germany, the Danube flows southeast for 2,850 km (1,770 mi), passing through or touching the border of Austria, Slovakia, Hungary, Croatia, Serbia, Romania, Bulgaria, Moldova and Ukraine before draining into the Black Sea. Its drainage basin extends into nine more countries. The Danube river basin is home to fish species such as pike, zander, huchen, wels catfish, burbot and tench. It is also home to a large diversity of carp and sturgeon, as well as salmon and trout. A few species of euryhaline fish, such as European seabass, mullet, and eel, inhabit the Danube delta and the lower portion of the river.
Steller's sea eagle
It lives in coastal northeastern Asia and mainly preys on fish and water birds. The Kamchatka Peninsula in Far Eastern Russia is known for its relatively large population of these birds. Around 4,000 of these eagles live there. Steller's sea eagle is listed as vulnerable on the International Union for Conservation of Nature (IUCN)'s Red List of Endangered species.
Goldstripe rasbora
The goldstripe rasbora ("Rasbora chrysotaenia") is a species of ray-finned fish in the genus "Rasbora". It is a benthopelagic freshwater fish found in Malaysia and Indonesia.
Ay River
Ay River (, ) is a river in Bashkortostan and Chelyabinsk Oblast in Russia, a left tributary of the Ufa River. The river is long, and its drainage basin covers . The Ay freezes up in late October or early November and remains icebound until mid-April. The cities of Zlatoust and Kusa are along the Ay River. Along the banks of the river, there are many steep cliff sides and caves. The current of the river has been used for hydroelectric power. It is also possible to fish for pike, bleak, and carp, to name a few species.
Ukrainian gudgeon
The Ukrainian gudgeon ("Gobio sarmaticus") is a species of gudgeon, a small freshwater fish in the family Cyprinidae. It is widespread in the lower parts of Dniester and Southern Bug drainages in Ukraine and Moldova. It is also likely to be present in the lower Dnieper River. It is a freshwater demersal fish, and grows up to 13 cm length.

Steinitz' prawn goby
Amblyeleotris steinitzi, Steinitz' prawn goby or simply Steinitz' goby, is a species of small fish in the family Gobiidae. It lives in association with an alpheid shrimp and is found from the Red Sea through the Indian Ocean to the western Pacific Ocean.
Back River (Virginia)
The Back River is an estuarine inlet of the Chesapeake Bay between the independent cities of Hampton and Poquoson in the Hampton Roads area of southeastern Virginia. Formed by the confluence of the Northwest and Southwest Branches, and at just over two miles long, the Back River is a breeding ground for many of the Bay's prized sport fish and the well known blue crab. The river was once part of an important fishing area that provided the local canneries with the famous Chesapeake seafood that was, and still is in demand throughout the country. Although now used primarily for recreation and as a wildlife refuge, the river remains a great place to spend an afternoon with a fishing rod or a few crab traps. Factory Point, a peninsula that protects the river from the Chesapeake Bay sits at the mouth of the river adjoining the bay.
Pecos gambusia
The Pecos gambusia ("Gambusia nobilis") is a species of fish in the family Poeciliidae endemic to the Pecos River in Texas and New Mexico in the United States. This two-inch species, as most of its family, is a livebearer. Females produce broods of up to 40 fry every four to five days. The fish are omnivorous, eating algae and small invertebrates, and are endangered due to loss of their spring-fed desert habitat.
