Notorious couple grab giant snake by the tail before dragging it around river in a boat

Brazil: It's the very definition of the phrase 'brave but stupid'.

A video has emerged that appears to show a couple chasing and taunting a yellow anaconda before dragging it around a river by its tail in Brazil.

In the amazing footage, the couple are heard laughing as they pull the anaconda through the water, refusing to let go.

The swollen-bellied snake attempts to flee as they repeatedly try to grab hold of it.         

After being posted on social media, the clip was picked up by Environmental Military Garden police, who set out to find the culprits.

According to reports in the South American country, the couple appeared to be "very simple and layman" and claimed they did not know the act was a crime.
