The explosion of animals is an uncommon event arising from natural causes or human activity. Among the best known examples are the post-mortem explosion of whales, either as a result of natural decomposition or deliberate attempts at carcass disposal. [1] Other instances of exploding animals are defensive in nature or the result of human intervention.
Natural explosions can occur for a variety of reasons. Post-mortem explosions, like that of a beached whale, are the result of the build-up of natural gases created by methane-producing bacteria inside the carcass during the decomposition process. [2] Natural explosions which occur while an animal is living may be defense-related. A number of toads in Germany and Denmark exploded in April 2005. [3] The Los Angeles Herald in 1910 reported a duck which exploded after consuming yeast. [4]
Various military attempts have been made to use animals as delivery systems for weapons. In Song Dynasty China, oxen carrying large explosive charges were used as self-propelled explosive missiles. [5] During World War II the United States investigated the use of "bat bombs", or bats carrying small incendiary bombs, [6] while at the same time the Soviet Union developed the "anti-tank dog" for use against German tanks. [7] Other attempts have included the so-called "kamikaze dolphins", intended to seek out and destroy submarines and enemy warships. [8] There have also been a number of documented incidents of animal-borne bomb attacks, in which donkeys, mules or horses were used to deliver bombs. [9] [10] [11]
Some insects explode altruistically, at the expense of the individual in defense of its colony; the process is called autothysis. Several species of ants, such as Camponotus saundersi in southeast Asia, can explode at will to protect their nests from intruders. [12] [13] C. saundersi, a species of carpenter ant, can self-destruct by autothysis. Two oversized, poison-filled mandibular glands run the entire length of the ant's body. When combat takes a turn for the worse, the ant violently contracts its abdominal muscles to rupture its body and spray poison in all directions. Likewise, many species of termites, such as Globitermes sulphureus , have members, deemed the soldier class, who can split their bodies open emitting a noxious and sticky chemical for the same reason. [14]
In January 1932, the Townsville Daily Bulletin , an Australian newspaper, reported an incident where a dairy cow was partially blown up and died on a farm at Kennedy Creek (near Cardwell, North Queensland). The cow had reputedly picked up a blasting cap in her mouth while grazing in a paddock. This was only triggered later, when the cow began to chew her cud, at a time when she was in the process of being milked. The cow had its head blown off by the resulting explosion, and the farmer milking the cow was knocked unconscious. [15]
The explosive rat, also known as a rat bomb, was a weapon developed by the British Special Operations Executive (SOE) in World War II for use against Germany. Rat carcasses were filled with plastic explosives, and were to be distributed near German boiler rooms, where it was expected they would be disposed of by burning, with the subsequent explosion having a chance of causing a boiler explosion. The explosive rats never saw use, as the first shipment was intercepted by the Germans; however, the resulting search for more booby trapped rats consumed enough German resources for the SOE to conclude that the operation was a success. [16]
In April 2005, toads in the Altona district of Hamburg were observed by nature protection officials to swell up with gases and explode, propelling their innards for distances of up to one meter. [17] These incidents prompted local residents to refer to the area's lake—home to the toads—as Tümpel des Todes, 'Pool of Death'.[ citation needed ] The incidents were reported as occurring with greatest frequency between 2 and 3 a.m. Werner Smolnik, an environmental movement worker, stated that at least 1,000 toads had died in this manner over the span of a few days. According to Smolnik, the toads expanded to three and a half times their normal size before blowing up. [17] The toads were noted to live a short time after exploding. [18]
Initial theories had included a viral or fungal infection, possibly one also affecting foreign horses involved in horse racing at a nearby track. However, laboratory tests were unable to detect an infectious agent. [17] Berlin veterinarian Franz Mutschmann collected toad corpses and performed necropsies, and hypothesized that the phenomenon was linked to a recent influx of predatory crows to the area. According to his theory, crows attacked the toads and picked out their livers through the skin between their chests and abdominal cavities. As a defensive mechanism, the toads enlarged themselves, but due to the hole in their body and their missing liver, their blood vessels and lungs ruptured and expelled their intestines. [17]
Mutschmann's theory was dismissed as unlikely by an ornithologist. The official report filed the incident as lacking a satisfactory explanation. [19]
The cane toad, also known as the giant neotropical toad or marine toad, is a large, terrestrial true toad native to South and mainland Central America, but which has been introduced to various islands throughout Oceania and the Caribbean, as well as Northern Australia. It is a member of the genus Rhinella, which includes many true toad species found throughout Central and South America, but it was formerly assigned to the genus Bufo.
A bomb is an explosive weapon that uses the exothermic reaction of an explosive material to provide an extremely sudden and violent release of energy. Detonations inflict damage principally through ground- and atmosphere-transmitted mechanical stress, the impact and penetration of pressure-driven projectiles, pressure damage, and explosion-generated effects. Bombs have been utilized since the 11th century starting in East Asia.
A harpoon is a long, spear-like projectile used in fishing, whaling, sealing, and other hunting to shoot, kill, and capture large fish or marine mammals such as seals, sea cows, and whales. It impales the target and secures it with barb or toggling claws, allowing the fishermen or hunters to use an attached rope or chain to pull and retrieve the animal. A harpoon can also be used as a ranged weapon against other watercraft in naval warfare.
The 2004 Madrid train bombings were a series of coordinated, nearly simultaneous bombings against the Cercanías commuter train system of Madrid, Spain, on the morning of 11 March 2004—three days before Spain's general elections. The explosions killed 200 people and injured around 2,500. The bombings constituted the deadliest terrorist attack carried out in the history of Spain and the deadliest in Europe since 1988. The attacks were carried out by individuals who opposed Spanish involvement in the 2003 US-led invasion of Iraq.
A rat king is a collection of rats or mice whose tails are intertwined and bound together in some way. This could be a result of an entangling material like hair, a sticky substance such as sap or gum, or the tails being tied together.
There have been several cases of exploding whale carcasses due to a buildup of gas in the decomposition process. This would occur if a whale stranded itself ashore. Actual explosives have also been used to assist in disposing of whale carcasses, ordinarily after towing the carcass out to sea, and as part of a beach cleaning effort. It was reported as early as 1928, when an attempt to preserve a carcass failed due to faulty chemical usages.
Cetacean stranding, commonly known as beaching, is a phenomenon in which whales and dolphins strand themselves on land, usually on a beach. Beached whales often die due to dehydration, collapsing under their own weight, or drowning when high tide covers the blowhole. Cetacean stranding has occurred since before recorded history.
Autothysis or suicidal altruism is the process where an animal destroys itself via an internal rupturing or explosion of an organ which ruptures the skin. The term was proposed by Ulrich Maschwitz and Eleonore Maschwitz in 1974 to describe the defensive mechanism of Colobopsis saundersi, a species of ant. It is caused by a contraction of muscles around a large gland that leads to the breaking of the gland wall. Some termites release a sticky secretion by rupturing a gland near the skin of their neck, producing a tar effect in defense against ants.

"Behavioral sink" is a term invented by ethologist John B. Calhoun to describe a collapse in behavior that can result from overpopulation. The term and concept derive from a series of over-population experiments Calhoun conducted on Norway rats between 1958 and 1962. In the experiments, Calhoun and his researchers created a series of "rat utopias" – enclosed spaces where rats were given unlimited access to food and water, enabling unfettered population growth. Calhoun coined the term "behavioral sink" in a February 1, 1962, Scientific American article titled "Population Density and Social Pathology" on the rat experiment. He would later perform similar experiments on mice, from 1968 to 1972.
Carpenter ants are large ants indigenous to many forested parts of the world.
Military animals are trained animals that are used in warfare and other combat related activities. As working animals, different military animals serve different functions. Horses, elephants, camels, and other animals have been used for both transportation and mounted attack. Pigeons were used for communication and photographic espionage. Many other animals have been reportedly used in various specialized military functions, including rats and pigs. Dogs have long been employed in a wide variety of military purposes, more recently focusing on guarding and bomb detection, and along with dolphins and sea lions are in active use today.
The Wind in the Willows is a 1996 British adventure comedy film based on Kenneth Grahame's 1908 novel The Wind in the Willows, adapted and directed by Terry Jones, and produced by Jake Eberts and John Goldstone. The film stars Terry Jones, Steve Coogan, Eric Idle and Nicol Williamson. While positively regarded, it was a box office bomb and had distribution problems in the United States.
Colobopsis saundersi, also called the Malaysian exploding ant, is a species of ant found in Malaysia and Brunei, belonging to the genus Colobopsis. A worker can explode suicidally and aggressively as an ultimate act of defense, an ability it has in common with several other species in this genus and a few other insects. The ant has an enormously enlarged mandibular gland, many times the size of other ants, which produces adhesive secretions for defense. According to a 2018 study, this species forms a species complex and is probably related to C. explodens, which is part of the C. cylindrica group.
The Animal Liberation Front (ALF) is an international, leaderless, decentralized movement that emerged in Britain in the 1970s, evolving from the Bands of Mercy. It operates without a formal leadership structure and engages in direct actions aimed at opposing animal cruelty.
The cane toad in Australia is regarded as an exemplary case of an invasive species. Australia's relative isolation prior to European colonisation and the Industrial Revolution, both of which dramatically increased traffic and import of novel species, allowed development of a complex, interdepending system of ecology, but one which provided no natural predators for many of the species subsequently introduced. The recent, sudden inundation of foreign species has led to severe breakdowns in Australian ecology, after overwhelming proliferation of a number of introduced species, for which the continent has no efficient natural predators or parasites, and which displace native species; in some cases, these species are physically destructive to habitat, as well. Cane toads have been very successful as an invasive species, having become established in more than 15 countries within the past 150 years. In the Environment Protection and Biodiversity Conservation Act 1999, the Australian government listed the impacts of the cane toad as a "key threatening process".
Parabiosis is a laboratory technique used in physiological research, derived from the Greek word meaning "living beside." The technique involves the surgical joining of two living organisms in such a way that they develop a single, shared physiological system. Through this unique approach, researchers can study the exchange of blood, hormones, and other substances between the two organisms, allowing for the examination of a wide range of physiological phenomena and interactions. Parabiosis has been employed in various fields of study, including stem cell research, endocrinology, aging research, and immunology.
Animal suicide is when an animal intentionally ends its own life through its actions. It implies a wide range of higher cognitive capacities that experts have been wary to ascribe to nonhuman animals such as a concept of self, death, and future intention. There is currently not enough empirical data on the subject for there to be a consensus among experts. For these reasons, the occurrence of animal suicide is controversial among academics.
Animal-borne bomb attacks are the use of animals as delivery systems for explosives. The explosives are strapped to a pack animal such as a horse, mule or donkey. The pack animal may be set off in a crowd.
Native to both South and Central America, Cane toads were introduced to Australia in the 1930s and have since become an invasive species and a threat to the continent's native predators and scavengers.
