Titanoboa is very similar to our modern-day green anaconda, living in swamps in the murky water, hiding and waiting for an unsuspecting animal to take a drink from the swamp, or preying on other aquatic animals. Titanoboa would be very slow and would not achieve much on dry land, which was its enemy, much like the green anacondas prefer the water as well. It probably could hold its breath underwater for about forty-five minutes, which is helpful for an aquatic ambush hunter.
