The video shows a snake vomiting a whole cow.
The video, allegedly taken in Brazil, shows a bloated snake. It slithers a bit then seconds later starts to regurgitate its meal.
The animal is thought to be a cow. Some say it might have been a capybara, a large rodent native to South America.
Green anacondas are the largest snakes in the world. It can grow up to 30 feet long and can weight more than 550 pounds.
