Current equipment for ponds and fountains give you the opportunity to complete the project reservoir at various levels of complexity.
Previously, when the device of the reservoir used crushed clay, then began to apply the concrete. In the recent past, concrete constructed ponds of various sizes – both large and not so large. Now in the construction of garden ponds the concrete, as a rule, do not apply – this is a very time-consuming equipment installation and dismantling.
Now in gardening there are two types of materials are ready – made plastic form and flexible insulation materials (PVC film). Before you build a pond from a plastic form you need to submit that visually, the form, in the garden, may be less than the store. In addition, You are limited to finished form. Much more interesting will turn out a cistern from PVC film. The bed of the stream and cascade also vystelite film. The device of the reservoir from PVC film. Continue reading
Underwater world conceals many mysteries, and the moon mankind has learned better than the bottom of the oceans. Blue in the water column live amazing marine life. The biggest, strongest and most poisonous animals live under the water and not on land.
Russian photographer Alexander Semenov spent hundreds of hours filming and documenting the lives of monsters from the depths of the oceans. Sea butterflies, marine worms, sea angels and many other inhabitants of the underwater world in today’s report.
He is a graduate of the Department of Zoology of the Moscow state University named after M. V. Lomonosov and underwater photographer.

The Barracuda is very similar to the pike, however, a large Barracuda (Sphyraenidae) and is called a sea pike for her appearance and hunting habits. It is the same long, agile and voracious freshwater predator. Its a bird elongated snout armed with powerful teeth, and front – clico prominent.
These fearsome marine predators are kept in small flocks. Dark back and light belly helps them to blend well even without shelter. Waiting for prey, they often hang at the edge of the coral reef. Hiding, almost not moving, only slightly moving his caudal and ventral fins. Approached the flock of fish barracudas will attack with lightning speed. Each predator chooses only one victim, not paying attention to the others. You can often watch from the water after the fish jump out of the sea pike. After a quick meal of Barracuda once again take a wait.
Barracudas belong to the order of kefalovrisia. Can reach lengths up to 3 m, but usually their size does not exceed 1 m Rod one – barracudas (Sphyraena). There are about 20 species in tropical and subtropical waters of the World ocean. In the Russian seas meet representatives of the two species. Continue reading
