Weight1075 kg (2,370 lb)

Lolong (died 10 February 2013) was the largest crocodile ever held in captivity. He was a saltwater crocodile (Crocodylus porosus) measured at 6.17 m (20 ft 3 in), making him one of the largest crocodiles ever measured from snout to tail, and weighing 1,075 kg (2,370 lb).[1][2][3][4]

In November 2011, British crocodile expert Adam Britton of National Geographic sedated and measured Lolong in his enclosure and confirmed him as the world's largest crocodile ever caught and placed in captivity.[5][2]

Lolong died on 10 February 2013, from pneumonia and cardiac arrest, after a little over one year and five months in captivity.[6]

Capture and habitat

[edit]

Lolong was caught in a Bunawan creek in the province of Agusan del Sur in the Philippines on 3 September 2011.[3][7] He was captured with the joint cooperation of the local government unit, residents, and crocodile hunters of Palawan in the Philippines. Along with the help of Kim Ramos, who happened to be a crocodile expert curious after hearing the story of Rowena Romano.

Hunted over a period of three weeks, it took around 100 people to bring him onto land.[8] He became aggressive at several points during the capture, and twice broke restraining ropes before eventually being properly secured.[9] He was estimated to be at least 50 years old.[10]

Lolong was first suspected of eating a fisherman who went missing in the town of Bunawan, and also of consuming a 10-year-old girl whose headless body was discovered two years earlier.[11] However, disagreement and speculation grew after Lolong's capture that an even larger alleged 24–29 ft (7.3–8.8 m) crocodile, nicknamed 'Potol', was responsible for the attacks. However, Lolong was also the primary suspect in the disappearance of water buffaloes in the known area. During the examination of the stomach contents after his capture, no human remains or remnants of water buffaloes reported missing before Lolong's capture were found.[12]

The nongovernmental organization activist Animal Kingdom Foundation Inc., with the cooperation of People for the Ethical Treatment of Animals, had urged the local government of Bunawan to return Lolong to the creek of barangay Nueva Era, where the giant reptile was captured.[13] But, in an ongoing debate, Bunawan mayor Edwin "Cox" Elorde and residents of the barangay opposed the crocodile's release, arguing that Lolong would threaten individuals living in the vicinity of the creek.[13]

Name

[edit]

The crocodile was named after Ernesto "Lolong" Goloran Coñate as one of the veteran crocodile hunters from the Palawan Crocodile and Wildlife Reservation Center, who led the hunt.[14] After weeks of stalking, the hunt for Lolong took its toll on Coñate's health. He died of a heart attack several days before the crocodile was captured.[15]

Captivity and display

[edit]

Bunawan made Lolong the centerpiece of an ecotourism park for species found in the marshlands near the township. Mayor Elorde said, "We will take care of this crocodile because this will boost our tourism and we know it can help in terms of town's income and jobs to our village communities."[16]

The ecopark charged a P20 entrance fee for adults and P15 for children, which supported the park's maintenance and procurement of Lolong's food.[17] The Bunawan Ecopark also incurred expenses for electricity, maintenance, and other incidental expenses, such as installation of CCTV cameras. According to Bunawan Mayor Elorde, up to 26 October 2011, the celebrity crocodile had already earned nearly half million pesos in donations, entrance fees, and parking fees, with a daily income of about P10,000 that month.[18]

Record holder

[edit]

In June 2012, six months after Australian zoologist and crocodile expert Dr. Adam Britton gathered measurements, Lolong was officially certified by the Guinness Book of World Records as the "world's largest crocodile in captivity" at 6.17 m (20 ft 3 in).[19][20][21] Experts from the National Geographic Channel found that Lolong had broken the record of the previous record-holder: a 5.48 m (18 ft 0 in) male saltwater crocodile named Cassius kept in the crocodile park of MarineLand Melanesia in Queensland, Australia. The certification was read in public during Bunawan's annual local festival, Araw Ng Bunawan (Bunawan Day).[22]

Lolong (died 10 February 2013) was a (Crocodylus porosus) captured in Bunawan, , , and recognized by as the largest ever held in captivity, with a length of 6.17 meters (20 feet 3 inches) from snout to tail and a weight of approximately 1,075 kilograms (2,370 pounds). The crocodile was apprehended in September 2011 following reports of fatal attacks on local villagers, including the consumption of at least one child, prompting a community hunt involving over 100 participants. Housed in an eco-park in Bunawan, Lolong drew significant tourism to the area before his death from and after about 17 months in captivity. His remains were later preserved and displayed at the .

Background and Capture

Natural Habitat and Predatory Behavior

Lolong inhabited Bunawan Creek, a marshy in the province of , , where estuarine waters support populations of saltwater crocodiles (Crocodylus porosus) alongside human communities dependent on the area for , , and riverine . This proximity in a resource-rich but conflict-prone heightens risks, as expanding human activities encroach on crocodile territories in the region's southern swamplands. The 's predatory actions in this habitat included documented attacks on , such as water buffaloes that were seized and partially consumed, evidencing its strategy of ambushing large terrestrial prey near water edges. Local reports also linked Lolong to suspected human incidents, including the disappearances of residents and at least two confirmed fatalities attributed to crocodile predation, prompting urgent intervention due to the direct threat to community safety. As an adult male C. porosus, Lolong exemplified the species' role as an opportunistic , employing stealthy ambushes to capture diverse prey ranging from and reptiles to sizable mammals, which it would drown before consumption. In Philippine estuarine systems like Bunawan Creek, such hypercarnivorous behaviors, supported by abundant prey availability, facilitate exceptional growth, with larger individuals actively patrolling territories and responding aggressively to potential food sources or intruders.

Capture Operation and Justification

The capture operation for the crocodile later named Lolong began in late in Bunawan, , , following heightened community concerns over attacks in local waterways. Local authorities, prompted by the disappearance of a in —suspected to have been killed by the animal—and a prior fatal attack on a in 2009, mobilized a hunt to neutralize the threat. Dozens of residents, under the coordination of Bunawan Mayor Edwin Elorde, collaborated with veteran crocodile hunters from , utilizing rudimentary steel cable traps baited in creeks rather than advanced equipment. The three-week effort, conducted amid challenging marshy terrain, ended successfully on September 3, 2011, when the crocodile was ensnared after weeks of stalking, though it claimed the life of one hunter via heart attack prior to success. This operation was justified as a necessary defensive measure against verifiable risks to safety in a rural, developing area where communities depend on proximate rivers for , with the crocodile's predatory actions empirically linked to at least two human deaths and posing ongoing peril to villagers and their economic activities. Such interventions reflect pragmatic responses to wildlife- conflicts in resource-limited settings, prioritizing causal prevention of further casualties over preservation of individual animals deemed habitual threats.

Identification and Physical Attributes

Measurements and Verification

Lolong's total length was measured at 6.17 meters (20 feet 3 inches) from snout to tail tip. This dimension was determined in November 2011 by a team led by expert , who sedated the in its enclosure to conduct the straight-line measurement along its body axis, addressing concerns over potential stretching or exaggeration in informal estimates. The crocodile's weight was recorded at approximately 1,075 kilograms (2,370 pounds) using a weigh-bridge scale shortly after capture. This method provided an objective bulk assessment, as direct weighing of such a large live specimen posed logistical challenges, and the result was cross-verified by officials to confirm its accuracy for record purposes. These measurements, grounded in expert fieldwork rather than anecdotal reports, established Lolong's exceptional size among documented saltwater crocodiles (Crocodylus porosus).

Naming and Biological Classification

Lolong was classified as a male , Crocodylus porosus, the largest extant species of crocodile and a member of the family Crocodylidae within the order . Native to the region, including coastal and estuarine habitats across such as the , C. porosus exhibits euryhaline , enabling it to osmoregulate effectively in salinities ranging from freshwater rivers to full-strength seawater. This adaptability distinguishes it from obligate freshwater congeners like the critically endangered (Crocodylus mindorensis), which lack comparable tolerance for marine conditions. Lolong was captured from the brackish Agusan Marsh ecosystem in Bunawan, , where such transitional waters support large individuals of the species. The name "Lolong" was assigned by the capture team led by local authorities in Bunawan following the crocodile's apprehension on September 3, 2011. While specific etymological details remain anecdotal in primary reports, it aligns with Philippine potentially honoring resilience or prominence, as reflected in local . Biological assessments, including size and osteological features, supported an age estimate exceeding 50 years at capture, aligning with growth trajectories for dominant males in C. porosus populations, where longevity can surpass a century in optimal conditions.

Captivity and Public Role

Enclosure Conditions and Daily Care

Lolong was maintained in a small open-air enclosure at the Bunawan Eco-Park and Research Centre, featuring a concrete-floored pen with a shallow originally designed for a approximately half his length of 6.17 meters. This setup, adapted from local materials amid limited resources, provided insufficient depth for full submersion or effective , confining the crocodile to restricted movement in a space inadequate for his 1,075-kilogram mass. Post-capture on September 3, 2011, Lolong exhibited feeding refusal for at least six days, attributed to handling-induced stress by local veterinarians, though saltwater crocodiles of his size can endure periods up to six months in . By early 2013, he ceased entirely approximately one month prior to his on February 10, reflecting compounded physiological strain. Care routines included oversight by local handlers and the municipal veterinarian, supplemented by monthly inspections from two Protected Areas and Wildlife Bureau (PAWB) veterinarians who assessed and administered basic treatments. Maintenance practices involved periodic draining of the pond to facilitate cleaning and inspection, which supported but removed hydrostatic support for Lolong's body weight, potentially aggravating joint and tissue stress over time. Poor in the shallow contributed to fungal infections affecting his and other tissues, as identified in post-mortem analysis by Department of Environment and Natural Resources (DENR) officials. The concrete substrate led to wear-related injuries, including fractured claws, damaged teeth, and resultant open sores.

Tourism Boost and Economic Benefits

Lolong's display at the Bunawan Eco-Park and Research Center drew thousands of tourists to the remote municipality of Bunawan, Agusan del Sur, following his capture on September 4, 2011. The influx transformed the park into a primary attraction, with visitors contributing to daily gate receipts of up to ₱20,000 from entrance and parking fees. Over the roughly 17 months from capture to his death on February 10, 2013, the facility generated at least ₱2 million in total earnings, including donations alongside fees. By late October 2011 alone, revenues approached ₱400,000, with portions allocated to local infrastructure like solid waste management in Barangay Consuelo. These funds and heightened foot traffic spurred ancillary economic activity, including sales from nearby vendors offering food and souvenirs, while creating jobs for park maintenance and guiding in a region with historically limited opportunities. Mayor Edwin Cox Elorde emphasized that Lolong's presence fostered new developments and sustained community benefits, such as improved local services funded by tourism proceeds. This model highlighted wildlife utilization as a viable strategy for economic uplift in rural Philippines, prioritizing measurable local gains over relocation debates.

Record Status and Comparisons

Guinness World Record Certification

Lolong was officially certified by as the largest ever held in captivity on July 3, 2012, measuring 6.17 meters (20 feet 3 inches) in length and weighing approximately 1,075 kilograms (2,370 pounds). This surpassed the previous record holder, Cassius, an Australian measured at 5.48 meters. The certification process involved independent verification to ensure accuracy and prevent measurement inflation, including detailed assessments by Australian zoologist and expert Dr. Adam , who conducted six months prior to the official announcement. Weight was confirmed using a weigh-bridge for precision, addressing potential discrepancies in earlier estimates. adjudicators reviewed these data against their standards for captive crocodilians, confirming the record after initial delays in on-site validation. As of October 2025, Lolong's record remains unbroken for the largest in , with no subsequent verified measurements exceeding 6.17 meters in controlled environments, despite occasional of larger wild specimens.

Comparisons with Other Notable Crocodiles

Lolong, measured at 6.17 meters in length and 1,075 kilograms in weight, surpassed Cassius, a captive in estimated at 5.48 meters long and approximately 998 kilograms, establishing Lolong as the largest verified specimen in captivity prior to his death. Cassius regained the title for living crocodiles after Lolong's passing, but lacks comparable verified metrics in both dimensions. Claims of larger wild saltwater crocodiles, such as historical unmeasured specimens or rumored giants exceeding 7 meters, remain unsubstantiated due to the absence of precise, verifiable measurements from snout to tail tip under controlled conditions. For instance, Gustave, a notorious Nile crocodile (Crocodylus niloticus) from Burundi rather than a C. porosus, has been estimated at around 6 meters based on eyewitness accounts and indirect assessments, but no direct physical verification exists, rendering such reports anecdotal rather than empirical. Recent Philippine sightings, including an 18-foot (approximately 5.5 meters) crocodile captured off Tawi-Tawi in January 2025, fall short of Lolong's documented size and highlight the challenges in confirming wild dimensions without post-capture analysis. Biologically, male C. porosus can theoretically attain lengths of 6 to 7 meters , influenced by factors like age, nutrition, and habitat, yet verified records cap at Lolong's measurements, positioning him as the empirical maximum for the species under documented captivity. This underscores the rarity of extreme sizes, as growth plateaus after maturity and environmental pressures limit outliers, with unverified wild claims often inflated by skin measurements or incomplete assessments that overestimate live totals.

Controversies

Animal Welfare Criticisms

Critics of Lolong's captivity highlighted the at Bunawan Ecopark as insufficiently sized and shallow for a 6.17-meter , originally designed for a specimen half its length, which restricted swimming and natural movement akin to a shallow pool. This setup reportedly induced stress and immobility, with the concrete base causing broken claws, lost teeth, and sores from attempts to escape or maneuver. Early signs of distress included Lolong's refusal to eat for six days following its September 2011 capture, attributed by officials to handling and confinement in the 800-square-meter pen. Care practices exacerbated issues, as the pond was frequently drained for tourist access, compromising and exposing the animal, while local authorities disregarded Protected Areas and Bureau recommendations for a larger habitat or release. Post-mortem analysis in February 2013 identified fungal pneumonia as the primary cause of death, with the infection impairing lung function, inducing breathing difficulties, and precipitating congestive heart failure alongside organ lesions. These conditions were linked by observers to captivity-induced stress weakening immunity, compounded by inadequate monitoring limited to monthly veterinary checks. Animal welfare advocates, including People for the Ethical Treatment of Animals (PETA), contended that such confinement inherently shortened lifespan by denying nocturnal foraging and habitat acclimation, rendering the animal's suffering foreseeable for ecotourism gains.

Human Safety and Community Defense Arguments

The capture of Lolong in Bunawan, Agusan del Sur, , on September 13, 2011, was prompted by its suspected involvement in multiple attacks, including the deaths of a 12-year-old girl whose torso was found in September 2011 and a earlier that year, amid reports of several other assaults in the area. Local residents, dependent on creeks and marshlands for and in this rural, fifth-class municipality, faced heightened risks from the crocodile's presence in shared waterways, justifying the three-week hunt involving over 100 villagers and professional trappers as a direct measure to avert further fatalities. By securing the 6.17-meter in captivity rather than releasing or euthanizing it, authorities mitigated ongoing threats to human life in a region where large saltwater crocodiles (Crocodylus porosus) frequently encroach on human territories due to overlap and resource scarcity. This approach aligned with established practices aimed at resolving human-crocodile conflicts through live capture and relocation to controlled environments, thereby protecting vulnerable communities without resorting to lethal methods that could undermine broader conservation efforts. In Bunawan, where and reliance on local waters amplify the stakes, such interventions prioritize empirical reduction over demands for immediate release, which experts note could exacerbate dangers given the animal's size and history of predation. Proponents of this strategy argue that in developing contexts like the ' Agusan Marsh, where human survival depends on accessing crocodile-inhabited areas, absolutist for predator overlooks causal realities of territorial disputes and underestimates the value of human lives in subsistence economies. The decision to maintain Lolong in a secure not only neutralized an immediate peril but also served as a deterrent model, fostering community-led defense against problem animals while channeling local fears into sustainable , thereby balancing with economic resilience. This pragmatic framework, rooted in documented attack patterns, underscores that effective conservation in conflict zones requires subordinating idealized to verifiable human protection imperatives.

Death and Aftermath

Cause of Death and Health Issues

Lolong died on , , roughly 18 months after his capture in September 2011. The crocodile was discovered flipped onto its back with a severely bloated abdomen inside its enclosure at the Bunawan Eco-Park and Research Center in , , and efforts to revive it failed over several hours. A necropsy conducted by veterinarians on February 12, 2013, determined the immediate causes of death as pneumonia and cardiac arrest, with contributing factors including a fungal infection in the lungs, myocardial degeneration, and chronic stress from confinement. Pathological examinations revealed lung wounds and fluid accumulation that impaired respiration, leading to systemic infection and heart failure; no toxins or external trauma indicative of deliberate harm were identified. In the weeks preceding death, Lolong displayed progressive and respiratory distress, with failed interventions using local antibiotics and supportive care limited by the absence of advanced veterinary facilities for large crocodilians. The enclosure's constrained space—measuring approximately 100 square meters—exacerbated physiological strain on the 1,075-kilogram specimen, underscoring logistical difficulties in maintaining megaherbivore-level without specialized .

Preservation and Research Utilization

![Preserved bones of Lolong at Philippine National Museum][float-right] Following Lolong's death on February 10, 2013, a necropsy was conducted, after which his remains were transferred to the for preservation. The process involved separating the skin from the bones, with the skin undergoing to retain its original shape and size, while the skeleton was cleaned and articulated. This , which took approximately five years, prevented decay and prepared the specimen for long-term storage and display. In June 2017, the preserved remains were transported to the in , where the taxidermied skin is exhibited in Gallery 1 focusing on Philippine , and the is suspended from the ceiling in the Ayala Reception Hall. These climate-controlled museum conditions maintain the specimen's integrity against degradation, ensuring accessibility for scientific examination. The preserved Lolong provides a rare opportunity for anatomical studies on extreme somatic growth in saltwater crocodiles (Crocodylus porosus), offering data on osteology and pathology in oversized individuals that could inform herpetological research on size limits and environmental factors influencing development. As a documented record-holder measuring 6.17 meters and weighing over 1,000 kilograms, the specimen supports comparative analyses with other crocodilian fossils and contemporaries, though specific peer-reviewed studies utilizing it remain limited as of 2025.

Legacy

Local Ecopark Development Efforts

Following Lolong's capture on , , Bunawan municipal officials rapidly established the Bunawan Eco-Park and Research Centre as a dedicated facility to house the crocodile, aiming to leverage its fame for local revenue and public education on . The park included a custom-built enclosure measuring approximately 8 meters by 6 meters, designed to accommodate Lolong's size while allowing visitor viewing, with entry fees set at P20 for adults and P15 for children on regular days. This initiative drew thousands of tourists, generating income that funded basic infrastructure improvements and positioned the site as a hub for community-led rather than reliance on external grants. Municipal Planning and Development Robert Floyd Salise outlined expansion proposals in late 2011, including the of cottages for overnight stays, additional enclosures for other , and enhancements to access roads from nearby highways to sustain visitor influx beyond Lolong's presence. These self-initiated efforts emphasized practical economic diversification, such as integrating local crafts and guided tours, to create long-term employment for residents in the rural province. Lolong's death on February 10, 2013, prompted commitments from Mayor Edwin Elorde to maintain park operations, with plans to the crocodile's remains in and repatriate them to Bunawan for permanent display, alongside further site development like expanded attractions to preserve momentum. Initial post-death awareness from global media coverage supported modest community-driven upkeep, though sustained funding challenges limited full realization of broader infrastructure goals by 2013.

Broader Impacts on Conservation and Crocodile Management

Lolong's capture and public exhibition heightened awareness of human-crocodile conflicts in the , prompting discussions on non-lethal management strategies to mitigate attacks while preserving crocodile populations. Philippine government officials noted that the crocodile's fame represented a significant asset for conservation , fostering greater public engagement with wildlife protection efforts amid rising habitat encroachments. This visibility underscored the empirical reality that large saltwater crocodiles (Crocodylus porosus) pose ongoing risks in populated areas, with data from conflict-prone regions indicating dozens of attacks annually in , thereby justifying targeted removals over indiscriminate habitat expansions. The case exemplified the practical utility of for problematic individuals, enabling from high-conflict zones to controlled environments and reducing immediate threats to communities without necessitating . Institutions dedicated to management in the emphasized that live captures like Lolong's primary goal was through sanctuaries, contrasting with local tendencies toward killing large specimens, and provided data-driven insights into sustaining viable populations via selective interventions. Such approaches align with causal factors in , where repeated human proximity amplifies , supporting policies that prioritize threat assessment over uniform protections. By highlighting the shortcomings of release-only protocols—which often result in and escalated risks—Lolong's management informed a shift toward tiered strategies, where high-threat animals are held indefinitely to safeguard both and viability. This rejection of absolutist drew from observable outcomes, such as sustained attack rates in areas lacking proactive controls, and paralleled global models emphasizing balanced harvesting and to avert population booms in anthropogenic landscapes. Lessons from the event advocated empirical evaluation of individual risk profiles, promoting adaptive practices that integrate local data on attack frequencies and pressures over ideological constraints.
