Titanoboa: The Largest Snake That Ever Lived

Sixty million years ago, the largest snake that ever lived moved through the swamps of ancient Colombia. Titanoboa stretched nearly 13 metres (42 feet) and weighed over a tonne. But for years, almost everything we believed about it — how it hunted, how it killed, what it meant — was wrong. This is the real story. In this episode: • How big Titanoboa really was — and how we know from just its spine • The discovery that fooled scientists (it was labelled a "petrified branch") • Why it was a fish-hunter, not a crocodile-strangler • How constriction actually kills — circulatory arrest in seconds • The "snake thermometer" and the climate debate it sparked • Vasuki indicus: the 2024 challenger from India • Why no snake this large could survive on Earth today Chapters 00:00 The snake that couldn't exist today 01:33 The world that built it 05:35 How big was Titanoboa? 07:42 How it really hunted 11:06 The snake as a thermometer 13:04 The challenger: Vasuki Based on Head et al. (2009, Nature), Datta & Bajpai (2024) and Smithsonian/University of Florida research.
