The term 'HUGE BOA' can be solved by the 8-letter word 'ANACONDA'. Anacondas are large, non-venomous snakes found in tropical South America. They are among the largest snakes in the world and can grow up to 17 feet long and weigh up to 550 pounds. Anacondas are semi-aquatic and are excellent swimmers, often found near rivers and streams. They are ambush predators and feed on a variety of animals, including birds, fish, and mammals.
