The largest of the boas is the Madagascar ground boa, which averages 6.5 feet in length but can reach 10 feet. Its geometric pattern of reddish-brown, creams, grays and black, helps the snake blend into the leaf-litter. The ground boa hunts mainly at night and is particularly fond of small mammals, including lemurs. The Dumeril's ground boa is a closely related species found in the drier western forests, which sometimes spends the day in the underground burrows of ant colonies.
