Important Anaconda Facts

There are two species of South American snakes that constrict their prey. The heavily built giant anaconda is usually about 16 ft (5 m) long, but can be longer than 24 ft (7.5 m), rivaling the largest pythons in length. The yellow anaconda is much smaller. Typically dark green with alternating oval black spots, the giant anaconda lives along tropical rivers east of the Andes and in Trinidad. It kills at night by lying in wait in water; it constricts prey as large as young pigs or caimans and occasionally forages in trees for birds. It may bear 75 live young at a time.
