Amazon com the Arkhangelsk province

Fishermen in the Arkhangelsk region took out a strange catch in the area of ferry crossing Bereznik and aspen: they pulled from the water an unusual fish with the head of a turtle and fossilized scales.

According to the newspaper “Dinovite”, the fish has a head like a Brontosaurus, and also a large barbed needles and petrified of the scales. Its mouth looks like a suction Cup, similar to the mouth of sturgeon. The fishermen studied the various pictures on the Internet, but found no mention of such unusual instances. However, similar features are observed in fish such as sea hare and monkfish.

Later, the fish was identified, it became clear that this brocade pterygoplichthys, or armored catfish. He eats algae, and it plant aquarists. The habitat of this catfish – the water of the Amazon and Orinoco.

Recently anglers and ichthyologists meet more and more exotic species in the rivers of the middle zone of our country. In 2012, about catching the same armored catfish reported in the press Penza:

In the waters of Sura caught brocade pterygoplichthys, or armored catfish. The unique find was made by the inspectors during one of the raids. In poaching networks found freshwater species, with a history spanning millions of years.

Despite its fearsome appearance, armored catfish are not dangerous. He is not a carnivorous species and feeds on vegetation. Aquarists give birth and for beauty, and for clearing blue-green algae, absorbed by pterygoplichthys.

This is one of the few species that do not have scales. On the body soma it is replaced by bony plates, forming a solid shell.

The usual habitat of this catfish are waters of the Amazon and Orinoco. But in recent years anglers and ichthyologists meet more and more exotic species in the rivers of the middle zone of our country.

“It often happens also such that together with the fish ROE and larvae of far Eastern species in our region can deliver is not peculiar to us fish,” – said Osipov.

Summer due to hot weather conditions in this river for catfish were quite comfortable, but winter wouldn’t he: too low temperature.
