Crocodile attacks on humans are common in places where large crocodilians are native and human populations live. Only 6 of the 23 crocodilian species are considered dangerous to adult humans, and only individuals 2 metres (6.6 ft) in length or more represent a serious danger to humans, as smaller crocodiles are considered incapable of killing humans. However, even the smallest species can inflict painful bites requiring stitches. In addition, a small child may be of a similar size to the prey of some of the crocodilian species incapable of preying on adult humans.
The two species with the most well-known and documented reputation for preying on humans are the Nile crocodile and saltwater crocodile. Each year, hundreds of deadly attacks are attributed to the Nile crocodile in sub-Saharan Africa. In Southeast Asia, Australia, New Guinea, Borneo, and the Solomon Islands attacks by saltwater crocodiles often occur. The mugger crocodile is also very dangerous to humans, killing many people in India every year. The American crocodile is considered to be less aggressive. Only a few (unverified) cases of American crocodiles fatally attacking humans have been reported. The black caiman is also responsible for several recorded human fatalities every year within the Amazon basin and the surrounding regions. The American alligator is responsible for human fatalities, with most occurring in Florida.
An accurate count of annual crocodile attacks on humans is difficult to obtain. Many of the areas in which humans and large crocodiles come into contact are remote, impoverished, or in areas of political unrest. Crocodile attacks are not always reported to local authorities, and some reports are difficult to verify. Nevertheless, some information does exist: for example, it was reported by CAMPFIRE in Zimbabwe that in the first ten months of the year in 2005 crocodiles were the number one cause of death in humans where wildlife was involved – with the number of deaths cited as 13.
Unlike other "man-eating" crocodiles, such as the saltwater crocodile, the Nile crocodile lives in proximity to human populations, so contact is more frequent. Although most attacks are not reported, the Nile crocodile is estimated to kill hundreds (possibly thousands) of people each year, which is more than all other crocodilian species combined. One study posited the number of attacks by Nile crocodiles per year as 275 to 745, of which 63% are fatal, as opposed to an estimated 30 attacks per year by saltwater crocodiles, of which 50% are fatal. In both species, the mean size of crocodiles involved in nonfatal attacks was about 3 m (9.8 ft) as opposed to a reported range of 2.5–5 m (8.2–16 ft) or larger for crocodiles responsible for fatal attacks. Since a majority of fatal attacks are believed to be predatory in nature, the Nile crocodile can be considered the most prolific predator of humans among wild animals.
The most deaths in a single crocodile attack incident may have occurred during the Battle of Ramree Island, on February 19, 1945, in what is now Burma. Nine hundred soldiers of an Imperial Japanese Army unit, in an attempt to retreat from the Royal Navy and rejoin a larger battalion of the Japanese infantry, crossed through ten miles of mangrove swamps that contained saltwater crocodiles. Twenty Japanese soldiers were captured alive by the British, and almost five hundred are known to have escaped Ramree. Many of the remainder may have been eaten by the crocodiles, although since this incident took place during an active military conflict, it is impossible to know how many deaths can be directly attributed to the crocodiles instead of combat-related causes.
It is estimated that each year hundreds of people die from crocodile attacks in Africa – many of these attacks are never reported in the media. Without an accurate reporting system in place, crocodile attacks in Africa are difficult to track and very few are reproduced here. The majority of attacks recorded below have occurred in Southeast Asia and Australia.
- On May 22, 1992, an Iban girl, Dayang anak Bayang was killed by Bujang Senang at Pelaban River, another tributary of the great Batang Lupar River near Lingga in Sri Aman Division, Sarawak, Malaysia. The crocodile was shot to death by several police sharpshooters and Iban hunters. It was the biggest and oldest crocodile ever caught in the area.
- In January 2001, attacks by mugger crocodiles were reported on tribal population around the Neyyar reservoir in Kerala, India. Muggers are raised and periodically released into the reservoir from the Neyyar crocodile centre. This rare display of aggression was found to be the isolated behaviour of an abnormal minority among the Neyyar muggers which are usually not known to attack humans.
- In October 2002, 23-year-old German student Isabel von Jordan was killed by a saltwater crocodile in Kakadu National Park, Australia while swimming in the billabong with her sister Valerie and a few other backpackers.
- Estimated to be around 20 feet (6.1 m) in length, and to weigh more than 2,000 pounds (907 kg) Gustave has been credited with killing hundreds of people at the Rusizi River in Burundi. Numerous capture attempts have been made, including using a massive bear trap in 2002; however, Gustave has evaded capture. Gustave is the basis of the film Primeval (originally titled "Gustave"), which follows a news team sent to Burundi to capture Gustave; while doing so they become a target of a warlord in the midst of an African civil war.
- In September 2005, Russell Harris, a 37-year-old British engineer, was killed by a large saltwater crocodile while snorkeling off Picnic Beach in Australia. His body was recovered.
- On March 19, 2006, University of Washington medical professor Richard Root, age 68, who had moved to alleviate a shortage of physicians, was killed on a wildlife tour of the Limpopo River when a crocodile emerged from the river, and pulled him underwater.
- In April 2007, a 9-year-old Chinese child was killed in a crocodile pool at the Silver Beach holiday resort in southwest Guangxi region.
- On February 8, 2009, 5-year-old Jeremy Doble was attacked by a crocodile in far north Queensland Daintree River, Australia. Police confirmed that human remains found in a saltwater crocodile caught nearby were those of the boy.
- In April 2010, a 25-year-old woman from New Jersey was killed by a saltwater crocodile while snorkeling in India's Andaman Islands. Havelock Island, where the attack took place, lies 45 miles from the Lohabarrack Salt Water Crocodile Sanctuary. Her boyfriend caught the attack on film; the camera was recovered two days later along with her remains.
- On December 7, 2010, South African outdoorsman Hendrik Coetzee was killed after being attacked by a crocodile. Coetzee was leading a kayaking expedition through Congo's Lukuga River at the time of the attack.
- On September 4, 2011, A 20.2-foot (6.17-metre) saltwater crocodile, believed to be the largest ever captured, was trapped in the southern Philippines after a spate of fatal attacks. The crocodile is suspected of eating a farmer who went missing in July in the town of Bunawan, and of killing a 12-year-old girl whose head was bitten off two years before.
- On May 29, 2016, 46-year-old Cindy Waldron and her childhood friend, Leann Mitchell, 47, went for a late night swim at Thornton Beach in Daintree National Park, to celebrate the end of Mitchell's cancer treatment. Waldron was snatched by a crocodile, and called for help. Mitchell tried to save her friend's life, but was unsuccessful. Waldron's remains were believed to be found inside a 14-foot crocodile on 3 June 2016.
Notable attack survivors
- Australian philosopher Val Plumwood survived a prolonged saltwater crocodile attack during a solo canoe excursion in Kakadu National Park in 1985. Plumwood recounted the details of the attack and her escape in her 1996 essay "Being Prey". Following the attack she spent a month in intensive care in Darwin hospital and required extensive skin grafts.
