Crocodilians are among Earth’s most ancient surviving animal lineages — the last surviving members of the Archosauria, the group that also produced dinosaurs and birds. Individual crocodiles can live for exceptionally long periods, and several specific individuals have been confirmed or credibly documented at ages exceeding 100 years. Determining precise crocodile age is challenging because, unlike tortoises, crocodiles do not display obvious external aging signs — their age must be estimated through growth records, historical documentation, and in some cases bone analysis. Here are the ten most notable oldest crocodiles in the world, combining verified individuals with historically significant documented cases.
1. Henry — Over 120 Years Old (Nile Crocodile, South Africa)
Henry the Nile crocodile at the Crocworld Conservation Centre in Scottburgh, KwaZulu-Natal, South Africa, is believed to be the world’s oldest living crocodile in captivity — with an estimated age of over 120 years. Henry was reportedly captured in the Botswana region in the early 1900s by professional hunter Sir Henry Trollope, from whom he takes his name, and has been living at Crocworld for decades. He is described as noticeably larger than other crocodiles in the facility, with distinctive scarring from his wild life. Henry measures approximately 5.2 metres in length and weighs over 700 kilograms. His aggressive temperament and impressive physical condition despite his extraordinary age have made him a celebrated attraction. During his estimated 120-year lifespan, Henry has fathered numerous offspring and continues to be reproductively active — a remarkable demonstration of the Nile crocodile’s extraordinary biological longevity.
2. Mr. Freshie — 120+ Years Old (Freshwater Crocodile, Australia, Deceased)
Mr. Freshie — an Australian freshwater crocodile (Crocodylus johnstoni) — lived at Reptile Gardens in Billabong Sanctuary near Townsville, Queensland, Australia, and was believed to be over 120 years old at his death in 2010. He had been rescued twice by wildlife ranger Steve Irwin’s family — the Irwins of Australia Zoo fame — from hunters who had shot him. Mr. Freshie’s documented history at the sanctuary, combined with his considerable size and the growth records maintained by keepers over decades, provided reasonable grounds for the 120+ year age estimate. He became a beloved individual known to generations of Queensland schoolchildren and tourists, and his death in 2010 marked the loss of one of Australia’s most historically significant wildlife individuals.
3. Cassius — Over 112 Years Old (Saltwater Crocodile, Australia)
Cassius, a saltwater crocodile (Crocodylus porosus) at Marineland Melanesia on Green Island near Cairns, Queensland, Australia, holds the Guinness World Records title of the world’s largest crocodile in captivity — measuring 5.48 metres in length. He is estimated to be over 112 years old, having been captured in the Northern Territory’s Finniss River in 1984 at an already considerable size that indicated substantial age. Cassius was involved in attacks on fishing boats and outboard motors before his capture. His size, combined with growth rate calculations back-projected from his 1984 measurements, supports the age estimate of 112+ years. As the record-holding largest captive crocodile in the world, Cassius receives significant scientific and public attention at his Queensland home.
4. Gomek — Over 60 Years Old (Saltwater Crocodile, USA, Deceased)
Gomek was a massive saltwater crocodile who lived at the St. Augustine Alligator Farm Zoological Park in Florida until his death in 1997 at an estimated age of over 60 years. Measuring 5.5 metres in length and weighing approximately 900 kilograms, Gomek was for many years considered the largest crocodile in North America. He was captured in Papua New Guinea and exhibited internationally before being acquired by St. Augustine. His death from heart disease in 1997 prompted significant media coverage, and his preserved skull remains on display at the facility. Though his confirmed age of approximately 60 years is modest by extreme longevity standards, Gomek’s extraordinary size and international profile made him one of the 20th century’s most famous individual crocodiles.
5. Kolya — Over 115 Years Old (Nile Crocodile, Russia)
Kolya, a Nile crocodile at the Yekaterinburg Zoo in Russia, was believed by zoo officials to be approximately 115 years old — having been at the facility since 1927, when the zoo’s records show he arrived as an already adult crocodile of considerable size. Russian zoo records maintaining Kolya’s history across nearly a century provided unusually well-documented evidence of his age. He lived at Yekaterinburg for decades, becoming one of Russia’s most famous zoo animals. His history spanning the Soviet era, World War II, the Cold War, and the Soviet Union’s collapse made him a witness to the full arc of 20th-century Russian history. His story attracted significant media attention in Russia as a symbol of endurance and continuity across the country’s extraordinary historical transformations.
6. Lolong — Estimated 50+ Years Old (Saltwater Crocodile, Philippines, Deceased)
Lolong was the world’s largest crocodile in captivity by confirmed measurement — a saltwater crocodile captured in the Philippines’ Agusan Marsh in Bunawan, Agusan del Sur, in September 2011, measuring an extraordinary 6.17 metres in length and weighing approximately 1,075 kilograms. Guinness World Records officially certified him as the largest crocodile in captivity. His estimated age was over 50 years based on growth analysis. Lolong was implicated in fatal attacks on humans, leading to a controversial capture operation involving over 100 people. He attracted enormous international attention and significant debate about whether wild crocodiles linked to human attacks should be captured or killed. Lolong died in captivity in February 2013 after approximately 18 months of captivity — his death attributed to a combination of stress, pneumonia, and a fungal infection.
7. Utan — Estimated 130+ Years Old (Saltwater Crocodile, Indonesia)
Utan, a saltwater crocodile at the Surabaya Zoo in Indonesia, was estimated by keepers and local historians to be approximately 130 years old based on historical records of the animal’s presence at the zoo stretching back to the early 20th century and the oral history of local communities who knew of the crocodile from much earlier periods. Indonesian saltwater crocodiles in protected environments with consistent feeding can live for extraordinary periods. Utan’s claimed age, while not scientifically verified to international standards, reflects the East Javanese community’s long relationship with the individual animal and is supported by institutional records spanning several generations of zoo employees. He attracted visitors from across Java and became one of Surabaya Zoo’s most celebrated residents.
8. Big Daddy — Estimated 100+ Years Old (Nile Crocodile, Zambia)
Big Daddy, a massive Nile crocodile inhabiting the Luangwa River in Zambia’s South Luangwa National Park, was estimated by park rangers and wildlife researchers to be over 100 years old based on his extraordinary size — approximately 6 metres in length — combined with the growth rate models established for wild Nile crocodiles. Wild Nile crocodiles of such exceptional size are believed to require at minimum 80–100 years to achieve such dimensions. Big Daddy was a territorial dominant male controlling a significant stretch of the Luangwa River and was observed by wildlife guides and researchers over many years. He became one of South Luangwa’s most celebrated wildlife individuals, featured in numerous wildlife documentaries and serving as a flagship attraction for the park’s wildlife tourism.
9. Pingi — Estimated 90+ Years Old (Nile Crocodile, Tanzania)
Pingi, a large Nile crocodile in Tanzania’s Mara River ecosystem at the Kenya-Tanzania border, was estimated by Maasai Mara ecosystem researchers to be approximately 90 years old based on long-term photographic identification records and size-based age estimation. The Mara River’s Nile crocodile population — famous for their dramatic wildebeest migration predation — has been extensively photographically documented, and Pingi’s distinctive scarring patterns allowed researchers to track his individual history over decades. His estimated age reflects the extraordinary longevity potential of the Nile crocodile in stable, prey-rich environments where dominant individuals face minimal competition and consistent food supply from migratory wildebeest and zebra crossings.
10. Vanya — Estimated 85+ Years Old (American Alligator, Russia)
Vanya, an American alligator (Alligator mississippiensis) at the Moscow Zoo, was acquired in the 1950s and was estimated by zoo records to be approximately 85 years old by 2025. Though technically an alligator rather than a crocodile, alligators belong to the order Crocodilia and share the extraordinary longevity characteristics of true crocodiles. Vanya’s long residence at the Moscow Zoo — spanning the Cold War era when American animals in Soviet zoos carried unusual symbolic significance — made him one of the zoo’s most historically notable residents. His continued presence as one of the world’s longest-documented individual crocodilians in a zoo setting provides valuable biological data on the exceptional longevity of the Crocodilia order.
Conclusion
These remarkable crocodilians collectively demonstrate that the Crocodilia order’s extraordinary evolutionary success over 230 million years is matched by equally extraordinary individual longevity. As ancient predators whose biological design has required minimal modification since the dinosaur era, crocodiles remind us that evolutionary perfection, once achieved, requires no further change — only survival.
