The largest crocodile ever recorded and comparable living specimens
Check out this answer from Consensus:
The largest crocodile ever recorded is Lolong, a saltwater crocodile measuring 6.17 meters in length. Comparable specimens, such as Dau Sau from Vietnam, suggest that crocodiles of similar size have existed and may still exist today. While no living crocodiles have been documented to exceed Lolong’s size, the potential for such large individuals remains, underscoring the impressive and sometimes daunting nature of these ancient reptiles.
Crocodiles have long fascinated both scientists and the general public due to their impressive size and ancient lineage. Among these formidable reptiles, some individuals have reached extraordinary sizes, making them subjects of significant interest in herpetology and paleontology. This article explores the largest crocodile ever recorded and examines whether any living crocodiles are of comparable size.
The Largest Crocodile Ever Recorded
The largest crocodile ever recorded is a saltwater crocodile (Crocodylus porosus) known as “Lolong.” Captured in the Philippines in 2011, Lolong measured an astounding 6.17 meters in length. The skull of Lolong, which measures 69.8 cm, provides a reliable basis for this length estimation2 4.
Another notable specimen is a large crocodile skull recovered from Can Tho, Vietnam, named “Dau Sau.” The skull length of Dau Sau is 70.7 cm, and based on known skull length to total length ratios, this crocodile is estimated to have been between 6.3 and 6.8 meters long. Although Dau Sau is slightly larger in skull length than Lolong, it is important to note that the total body length estimation places it in a similar size range2 4.
Comparable Living Specimens
While Lolong holds the record for the largest confirmed living crocodile, there are other notable large crocodiles that have been documented. For instance, the crocodile specimen from the Pleistocene of Kali Gedeh, Java, is estimated to have reached a total length of approximately 6 to 7 meters based on the size of its lower jaw, which measures about 1 meter5. This specimen, although not living, provides evidence of gigantism in Crocodylus and suggests that such sizes were not uncommon in the past.
In terms of living specimens, there are no current records of crocodiles that match or exceed the size of Lolong. However, the existence of large crocodiles like Dau Sau and historical reports of similarly sized individuals indicate that such sizes are within the realm of possibility for living crocodiles.
