The mutant fish was caught in a net in the Northern Dvina River near a ferry terminal in Bereznik-Osinovo, Arkhangelsk Oblast, local media reports.
The fishermen were unable to identify what kind fish it was. The creature's head reminds one of a tortoise and its scales are fossilized. It also has thorny needle-like barbs and a sucker.
Its appearance is a bit similar to the angler, a predatory European deep-sea fish. Some people say it may be a rabbit fish which, however, is also a sea-fish - not a river one. The mouth of the fish looks like that of a sterlet - but the whole fish is a far cry from it.

It is not the first time that a strange fish has been caught in the Arkhangelsk region. Last year local fishermen caught a fish with human-like teeth. Scientists deduced that was a South American pacu fish which is a kind of piranha.
