Yellow anaconda

The yellow anaconda is a hefty snake that calls the wetlands and rivers of southern South America home. Though not the biggest anaconda, it's still one of the largest snakes around, squeezing its prey instead of using venom.

• Found only in southern South America, from Paraguay to northern Argentina.
• Uses powerful coils to subdue prey rather than venom.
• Smaller than its cousin, the green anaconda, but still massive.
