Titanoboa is a constrictor snake of immense size, dwarfing even the largest anacondas. Thick and bulky, they are found in large numbers in the island’s swamps, ambushing their prey in the shallows and crushing them between their coils; they are also found in large caves, where their apparent immunity to invertebrate toxins protects them from other cave dwellers. Their bulk prevents them from attracting the attention of most predators, but if threatened, the giant snake deploys a frill on its neck and attacks, biting with several rows of recurved needle-like teeth.
