An unidentified man had to have a South American Lungfish surgically removed after he inserted it up his anus.
According to reports, the man sought medical help at Hospital Universitario in Brazil after the fish wriggled into his intestines.
While he recovered from the operation, the fish had to be euthanized despite still being alive when removed by doctors.
The man has allegedly taken legal action and lodged a formal complaint through his solicitor after footage of the operation emerged online.
