Anaconda (Eunectes)

The dense jungles of South America have lush vegetation, bursting rivers, and marshlands. Within their depths live hulking creatures such as the Anaconda, one of the world's longest snakes (the green Anaconda is the longest).

The Anaconda can remain submerged for up to ten minutes and patiently wait for its prey to come close. 

Rather than expending energy, the Anaconda prefers to wait and ambush fish, birds, tapirs, and wild pigs, and it can go without food for months to a year due to its slow metabolism. 

When it does eat, it constricts its prey’s body to kill it and aid digestion. 

Despite their intimidating appearance, anacondas prefer to avoid confrontation unless provoked.
