Typically, sharks are considered extremely dangerous animals, and call it being an ordinary fish is sometimes more than difficult. This is not surprising, because, just look at the size of that “fish” and the number of teeth in her mouth. Indeed, virtually all species of sharks are predatory animals. It is immediately noted that there are about 450 different species. However, there are sharks that are as food prefer small fish, plankton, who lives in the water, etc. in Other words, some sharks are natural purifying devices for water. As it turned out, sharks can live not only in seawater, i.e., salt, but also in fresh waters. However, this ability is given not to all representatives of this genus of animals. In this game we will talk about predatory sharks that feed on large species of aquatic creatures.
Moreover, sometimes they are not averse to eat people if they are nearby. The game shark is one fish mysteriously swam in the waters of the river called Thames. It flows through London which is the capital of great Britain. At this time you have to control the movements and actions of a Continue reading
Goldfish (lat. Carassius auratus auratus) subspecies of the freshwater fish of the genus carp. Her ancestor was domesticated by the man in the VII century ad, and is one of the most popular aquarium fish, presented to a group of breeds of domestic aquatic animals, obtained as a result of centuries of hybridization and directional selection individuals with certain accidental characteristics, resulting from mutations. One of the obsolete naming all home and pond “goldfish” was “gold carp”, derived from General scientific systematic names, Carp.
The history of breeding goldfish Asia has at least a Millennium and originated from children’s hobby to collecting in which the housing was offered and developed in cages, in pens, in wells, in tubs and barrels for all small and medium animals — as the first kind of Pets at home. Continue reading
The greatest length of the Black sea from North to South — 580 km and a maximum depth of 2210 m, the average — 1240 m. the salinity of the water is approximately 18 ppm. The depth increases pretty quickly. Over a sloping beach near Evpatoria, Feodosia. On the South coast, in mountain areas, the depth increases more rapidly: a few meters from the shore you have to swim (or, in the alternative, to swim along the shore). Be careful, even at a short distance from the shore can be strong currents to deal with which is not prepared person is quite difficult. But mostly this does not apply to places of mass bathing (if not to swim too far). Waters of the Black sea, as a rule, not susceptible to freezing. The average sea temperature in winter ranges from +6 to +8 degrees, in summer — from +22 to +24 degrees (can warm up to 26 degrees in a particularly hot summer). However, it is worth noting that the Black sea could throw a “surprise”: one day deep cold currents cool the coastal waters up to 12 degrees, even Continue reading
