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. Other attempts have included the so-called " kamikaze dolphins", intended to seek out and destroy submarines and enemy warships. During World War II the United States investigated the use of " bat bombs", or bats carrying small incendiary bombs, while at the same time the Soviet Union developed the " anti-tank dog" for use against German tanks. In Song Dynasty China, oxen carrying large explosive charges were used as self-propelled explosive missiles. Various military attempts have been made to use animals as delivery systems for weapons. The Los Angeles Herald in 1910 reported a duck which exploded after consuming yeast.

A number of toads in Germany and Denmark exploded in April 2005. Natural explosions which occur while an animal is living may be defense-related. 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. Natural explosions can occur for a variety of reasons. Other instances of exploding animals are defensive in nature or the result of human intervention. 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. The explosion of animals is an uncommon event arising through natural causes or human activity.
