Watch cow angrily attack anaconda that killed its calf

But the five-metre anaconda, which has been lassoed with ropes by three farm workers, who are trying to pull it away from the scene, isn't easily cowed by the furious animal's actions.

Under attack, the snake fights back, tries to bite the mum then attempts to start the swallowing process by opening its jaws near the dead calf's body.

Stomping down hard on its slithering adversary, the cow does its best to prevent the deadly beast from getting close but it's a tough battle and she leaps away in shock as she gets bitten time and again.
