The green anaconda is considered to be one of the largest species of snakes in the world, with some specimens reaching 29 feet in length and weighing as much as 550 pounds. Although reticulated pythons can grow longer, experts contend that the green anaconda is significantly heavier.
Anacondas belong to the boa family of constrictor snakes and live in swamps and marshes throughout South America. Females are larger than the males and retain their eggs. They give birth to about three dozen fully formed young. Juvenile anacondas are capable of swimming and hunting immediately after birth. According to National Geographic, adults have been known to eat capybara and caimans whole and have even consumed jaguars.
