Is this the biggest snake ever? Construction workers discover 10m anaconda on a Brazilian building site

Constructions workers in Brazil had quite the surprise when they discovered a giant
anaconda on the site. The explosion of a cave during construction work at the Belo Monte dam in the municipality of Altamira in Para Brazil left workers frightened. But they got an even bigger scare when a giant snake weighing 400kg and measuring 10 metres emerged from the explosion.
