The discovery of Titanoboa provided valuable evidence in deciphering the Paleocene climate. Snakes are ectothermic, meaning they regulate their body temperature by exchanging heat with the surroundings. For Titanoboa to reach such an immense size, suggests that the Earth’s climate was a lot warmer than it is today. 
How Titanoboa hunted is a matter of speculation, some scientists suggest that it hunted like a modern day boa constrictor, by wrapping around prey so tight the unfortunate animal suffocated. Yet many believe that its form of hunting was more tactical, submerging itself in the water and waiting until some got too close, where it would then lurch forward and snap its jaws around the animals windpipe. Whatever the reality, the cause of death was likely to be by suffocation. 

The fact that Titanoboa was able to reach such a large such due to climatic factors,  has lead to ideas that as our planets temperature continues to rise, this infamous snake could make a return. Whilst there certainly is a possibility that snakes would be able to grow in size in a warmer world, this process takes millions of years. If Titanoboa was to make a return, it will be a long while yet before this Titan becomes a threat…
