The longest snake ever recorded
Check out this answer from Consensus:
The discovery of Titanoboa cerrejonensis has significantly expanded our understanding of the potential size limits of snakes, both in the past and present. While modern snakes like the reticulated python and green anaconda continue to impress with their size, the prehistoric Titanoboa remains the undisputed giant of the snake world. Ongoing research and fossil discoveries will undoubtedly continue to shed light on the fascinating history of these incredible reptiles.
Snakes have fascinated humans for centuries, not only because of their often mysterious and dangerous nature but also due to their impressive sizes. Among the many species of snakes, some have reached extraordinary lengths, making them subjects of significant scientific interest. This article explores the longest snake ever recorded, drawing on various research studies to provide a comprehensive overview.
The Titanoboa: The Largest Snake Ever
The title of the longest snake ever recorded goes to the Titanoboa cerrejonensis, a prehistoric snake that lived approximately 58-60 million years ago during the Paleocene epoch. Discovered in the Cerrejón Formation in northeastern Colombia, this giant boid snake is estimated to have reached a length of 13 meters (about 42.7 feet) and weighed around 1,135 kilograms (about 2,500 pounds)2. The discovery of Titanoboa has provided significant insights into the climate and environmental conditions of ancient tropical ecosystems, suggesting that the high temperatures of the Paleocene neotropics facilitated the evolution of such large body sizes among poikilothermic (cold-blooded) animals.
Other Notable Large Snakes
While Titanoboa holds the record for the longest snake ever, several other species have also achieved remarkable lengths:
Palaeophis oweni
Palaeophis oweni, a species from the Eocene epoch, is the largest snake known from the Italian fossil record. Although not as long as Titanoboa, P. oweni represents a significant find in the study of ancient snakes. This species has been redescribed based on fossils from Monte Duello, near Verona, Italy, highlighting its importance in understanding the diversity and evolution of ancient snakes in Mediterranean Europe1.
Modern Large Snakes
In the modern era, the reticulated python (Python reticulatus) and the green anaconda (Eunectes murinus) are among the longest snakes. The reticulated python holds the record for the longest living snake, with some individuals reaching lengths of over 10 meters (about 32.8 feet). The green anaconda, while shorter in length, is known for its massive girth and weight, making it the heaviest snake in the world.
