Yellow anaconda

Common names: yellow anaconda, Paraguayan anaconda.

Eunectes notaeus is a nonvenomous boa species found in South America. No subspecies are currently recognized.

Adults are not as large as the green anaconda, E. murinus, but nevertheless grow to an average of 10 to 12 feet (3.0 to 3.7 m) in length. The maximum size is almost certainly larger. Females are larger than males.

The color pattern consists of a yellow, golden-tan or greenish-yellow ground color overlaid with a series of black or dark brown saddles, blotches, spots and streaks.
