The blue anaconda (Eunectes caeruleo) is a nonvenomous boa species endemic to South America.


The blue anaconda is a pale blue color, with navy blue blotches bordered in black along the back. They are an average of about 14.5 feet (4.42 m), but can grow up to 19 feet (5.79 m). The longest recorded specimen was 23.4 feet (7.13 m). It was found in 1950, in Villa Ballester, Argentina. A man named Gil Figueroa supposedly stabbed it to death while it was constricting a deer. The deer died a few hours later of wounds.


Blue anacondas eat a wide variety of prey, including fish, a variety of mammals, and other reptiles. Some large anacondas may even eat prey such as deer, impalas, and springboks, but such large meals are not regularly consumed. They use constriction to kill their prey.
