Under the collective name of soma mean — more than 2,000 species of baleen variety of fishes from 31 families. Most of them inhabit freshwater reservoirs 5 continents (only 1% of marine residents). Only in the rivers and lakes of South America is home to about 1000 species. often the body of the fish is covered with bony plates, or protected by spikes. Thanks to the auxiliary respiratory organs (skin, outgrowths of the Gill bars, etc.) soma is not drawoutline to oxygen. They are predominantly benthic lifestyle returnee also be armed and at night.
Ordinary som belongs to a 5-meter high giants, and a parasitic catfish no larger than 2.5 cm Elektroniskie soma can cause significant shocks, and castkova, kilbowie, etc. the vibration fins, swim bladder, etc. can make sounds. Attached to the bottom substrate by using the suction cups loricaria. security, etc. are held in swift current And blind Satan, Trogloglanis (South America) and Ugittflanis (Africa) settled deep underground in caves and artesian basins. Among them are quite transparent glass Physailia catfish, Tandanus, Parailia and others). Continue reading
Sharks are found in open and coastal ocean waters. These mysterious creatures appeared on Earth 400 million barrels. years ago. Belong to cartilaginous fish. as their skeleton consists of cartilage. Cartilage is durable, and unlike the bones of fish, more flexible and light. They have no swim bladder. Afloat fish holds, thanks to its large but lightweight the liver. Her need to constantly move in order not to drown.
She swims, arching his whole body from side to side. Almost all of them when hunting using the electric field. Sharks capture him with the help of numerous electrical sensors that are on her face.
Many of them, it is not strange, they eat plankton. Plankton is a conglomeration of various microscopic and small organisms. Mainly unicellular plankton contains algae, which absorb solar energy, thereby transforming inorganic substances into organic food. Continue reading
As you know, climate change and mutation of animals has ceased to be a rarity and few people are surprised. Familiar to the inhabitants of Rome and became such a spectacle: from the waters of the river Tiber at any time of the day popping two-metre catfish, grab birds, politisk too close to the water, and eat them. Eaten can be also rats, mice, otters and even dogs.
These catfish are called “river sharks”. This is not normal peaceful fish, which we used to see in domestic rivers and lakes, and predatory violators of the laws of nature. By studying quick and terrifying mutation data of fishes was carried out by scientists from the University of Toulouse, France.
As a result, they came to the conclusion that it is absolutely uncharacteristic for som behavior is attributable to poor environmental conditions. Because of her, there was a significant depletion of the river bottom, fish and algae huge catfish was not enough to be sated, and they began to “jump” on anything they can catch. There are even cases when catfishes mutants tried to attack the man. Continue reading
