WARNING: GRAPHIC CONTENT According to Hospital Universitario, in Brazil, the unnamed man decided to put the fish into his own rear
This is the revolting moment doctors pull a LIVE FISH from a man's intestine - after it had shot up his backside.
According to Hospital Universitario in Londrina, a city in southern Brazil, the unnamed man decided to put the fish into his own rear as part of a bizarre sexual fantasy.
Instead of being able to pull it out, the South American Lungfish wriggled its way up into the gentleman's guts, passing a 'considerable way' before he sought medical help.
The fish was surgically removed by doctors who say they have "no idea" how the footage ended up being leaked onto social media.
However, the footage clearly shows many people standing in the background dressed in surgical gear and watching.
Several appear to have mobile telephones recording the incident.
Doctors can be heard laughing as the fish is surgically removed and one is heard to say: "This one is for the history", while another adds: "I have just sent the pic by mail."
The fish was apparently still alive after being removed but had to be euthanised.
The South American Lungfish can apparently exist in areas with very little oxygen and its typical environment is swampland and slow-moving waters.
The unidentified man from Londrina, who has recovered from the operation, has made a formal complaint via his solicitors about the fact that his rear end and the fish have now become viral sensations.
This is not the first time a fish was lodged in a man's rear end.
Back in 2013 a Chinese man from the south-eastern province of Guangdong was admitted to a local hospital after he inserted a live, 20-inch-long eel into his anus.
