Zamna Kogi
Zamna ( sr, Замна) is a river in eastern Serbia, the right tributary to the Danube. Its valley is known for the caves, arches and a canyon. Local population also calls it Zemna. Course and geography Zamna originates on the eastern slopes of the Deli Jovan mountain, below the Crni Vrh, at an altitude of . It originally flows in an easterly direction. At the village of Plavna, it receives the river Medveđa (also known as Medvedica) from the left. At the mouth, the river formed ''prerast'', or natural arch. Obscured by the thick forest, it is called ''Rajski prerast'' ("Paradise Arch") and is away from the center of the village. Cave arches are formed when the porous, limestone ceiling of the cave collapses. Zamna's "Paradise Arch" is the tallest rocky arch in Europe. Austrian traveler Felix Philipp Kanitz visited the area in the second half of the 19th century. He described the Deli Jovan mountain as rising above the river in four terraces, and the local tree flora whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Grass Snake
The grass snake (''Natrix natrix''), sometimes called the ringed snake or water snake, is a Eurasian non-venomous colubrid snake. It is often found near water and feeds almost exclusively on amphibians. Subspecies Many subspecies are recognized, including: ''Natrix natrix helvetica'' ( Lacépède, 1789) was formerly treated as a subspecies, but following genetic analysis it was recognised in August 2017 as a separate species, ''Natrix helvetica'', the barred grass snake. Four other subspecies were transferred from ''N. natrix'' to ''N. helvetica'', becoming ''N. helvetica cettii'', ''N. helvetica corsa'', ''N. helvetica lanzai'' and ''N. helvetica sicula''. Description The grass snake is typically dark green or brown in colour with a characteristic yellow or whitish collar behind the head, which explains the alternative name ringed snake. The colour may also range from grey to black, with darker colours being more prevalent in colder regions, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crayfish
Crayfish are freshwater crustaceans belonging to the clade Astacidea, which also contains lobsters. In some locations, they are also known as crawfish, craydids, crawdaddies, crawdads, freshwater lobsters, mountain lobsters, rock lobsters, mudbugs, baybugs or yabbies. Taxonomically, they are members of the superfamilies Astacoidea and Parastacoidea. They breathe through feather-like gills. Some species are found in brooks and streams, where fresh water is running, while others thrive in swamps, ditches, and paddy fields. Most crayfish cannot tolerate polluted water, although some species, such as ''Procambarus clarkii'', are hardier. Crayfish feed on animals and plants, either living or decomposing, and detritus. The term "crayfish" is applied to saltwater species in some countries. Terminology The name "crayfish" comes from the Old French word ' (Modern French '). The word has been modified to "crayfish" by association with "fish" (folk etymology). The largely American ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Barbel
The common barbel, ''Barbus barbus'', is a species of freshwater fish belonging to the family Cyprinidae. It shares the common name 'barbel' with its many relatives in the genus ''Barbus'', of which it is the type species. In Great Britain it is usually referred to simply as the barbel; similar names are used elsewhere in Europe, such as ''barbeau'' in France and ''flodbarb'' in Sweden. The name derives from the four whiskerlike structures located at the corners of the fish's mouth, which it uses to locate food. Distribution and habitat ''B. barbus'' is native throughout northern and eastern Europe, ranging north and east from the Pyrénées and Alps to Lithuania, Russia and the northern Black Sea basin. It is an adaptable fish which transplants well between waterways, and has become established as an introduced species in several countries including Scotland, Morocco and Italy. Although barbel are native to eastern flowing rivers in England, they have historically been transloca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gobio Gobio
''Gobio gobio'', or the gudgeon, is a species of fish in the family Cyprinidae. This small fish is widely distributed in fresh-water streams and lakes across central and temperate Eurasia.

Trout
Trout are species of freshwater fish belonging to the genera '' Oncorhynchus'', ''Salmo'' and ''Salvelinus'', all of the subfamily Salmoninae of the family Salmonidae. The word ''trout'' is also used as part of the name of some non-salmonid fish such as ''Cynoscion nebulosus'', the spotted seatrout or speckled trout. Trout are closely related to salmon and char (or charr): species termed salmon and char occur in the same genera as do fish called trout (''Oncorhynchus'' – Pacific salmon and trout, ''Salmo'' – Atlantic salmon and various trout, ''Salvelinus'' – char and trout). Lake trout and most other trout live in freshwater lakes and rivers exclusively, while there are others, such as the steelhead, a form of the coastal rainbow trout, that can spend two or three years at sea before returning to fresh water to spawn (a habit more typical of salmon). Arctic char and brook trout are part of the char genus. Trout are an important food source for humans and wildlife, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maize
Maize ( ; ''Zea mays'' subsp. ''mays'', from es, maíz after tnq, mahiz), also known as corn (North American and Australian English), is a cereal grain first domesticated by indigenous peoples in southern Mexico about 10,000 years ago. The leafy stalk of the plant produces pollen inflorescences (or "tassels") and separate ovuliferous inflorescences called ears that when fertilized yield kernels or seeds, which are fruits. The term ''maize'' is preferred in formal, scientific, and international usage as a common name because it refers specifically to this one grain, unlike ''corn'', which has a complex variety of meanings that vary by context and geographic region. Maize has become a staple food in many parts of the world, with the total production of maize surpassing that of wheat or rice. In addition to being consumed directly by humans (often in the form of masa), maize is also used for corn ethanol, animal feed and other maize products, such as corn starch and ...

Moss
Mosses are small, non-vascular flowerless plants in the taxonomic division Bryophyta (, ) '' sensu stricto''. Bryophyta (''sensu lato'', Schimp. 1879) may also refer to the parent group bryophytes, which comprise liverworts, mosses, and hornworts. Mosses typically form dense green clumps or mats, often in damp or shady locations. The individual plants are usually composed of simple leaves that are generally only one cell thick, attached to a stem that may be branched or unbranched and has only a limited role in conducting water and nutrients. Although some species have conducting tissues, these are generally poorly developed and structurally different from similar tissue found in vascular plants. Mosses do not have seeds and after fertilisation develop sporophytes with unbranched stalks topped with single capsules containing spores. They are typically tall, though some species are much larger. ''Dawsonia'', the tallest moss in the world, can grow to in height. There are a ...
