20 Animals Used in Completely Unexpected Jobs

In the 1880s, a chacma baboon named Jack helped James Wide, a disabled railroad signalman living near Uitenhage, South Africa. Jack reportedly learned, under supervision, to push Wide’s cart and operate the signal levers, making him one of the first—if not the only—baboons to have worked on the railroad.

As part of a research project, bees were trained to respond to the scent of explosive substances. The method took advantage of their natural foraging instinct: the insects were taught to associate certain chemical odors with a reward in the form of sugar syrup. Tiny and fuzzy, they were, in a sense, recruited for security missions.

Ferrets are used to feed cords, wires, and cables through narrow spaces that are inaccessible to people or tools. Their long, slender bodies make them particularly useful in ducts, pipes, wall cavities, and tunnels.

Giant African pouched rats have been trained to detect landmines and traces of explosives in former conflict zones. Their light weight allows them to traverse dangerous terrain without triggering most pressure-activated mines, while their highly developed sense of smell helps dog handlers identify hazardous areas.

In the past, in Great Britain, spit-roasting dogs were bred to run inside wheels that turned the meat being roasted over an open fire. It was hard, tiring, and repetitive work, and sometimes these dogs were used in pairs so they could take turns. It’s an ingenious idea, but we’re really glad we no longer need dogs to do that today.

Carrier pigeons were used to transmit short messages during wartime, especially when other means of communication were unavailable. During World War I and World War II, they braved perilous conditions to deliver information between soldiers, ships, and command posts. People often make fun of pigeons today, but their role in wartime deserves more respect.

Armies in ancient times used war elephants, particularly in India, Persia, and certain regions of the Mediterranean world. Their size made them formidable on the battlefield, especially against soldiers who had never faced animals of such magnitude in combat.

Near Eden, in New South Wales, local accounts and archives describe orcas working alongside whalers on shore in Twofold Bay. The most famous orca, Old Tom, made his mark on the region’s whaling history after helping to herd baleen whales toward the ships. It was a strange but useful relationship.

Dolphins have been trained to carry out underwater military missions thanks to their speed, intelligence, and echolocation abilities. They help locate objects in ports, coastal waters, and deeper areas where murky water makes human searches difficult.

According to Roman tradition, the sacred geese of the Capitoline Hill are said to have sounded the alarm during a nighttime attack by the Gauls in 390 B.C. The story goes that their cries woke the defenders just as the danger had already slipped past the other guards’ vigilance.

Seals have been fitted with sensors that collect oceanographic data as they dive. Their movements allow researchers to measure parameters such as temperature, salinity, and depth in remote waters, including hard-to-reach polar regions. These highly skilled animals have provided data that humans could not have easily collected on their own.

Livestock can reduce dry vegetation by grazing in carefully selected areas. In some regions of the American West, targeted grazing has been studied as a way to create firebreaks and reduce the risk of wildfires. Animals are not firefighters, but with proper management, their feeding habits can contribute effectively to fire prevention.

Electric eels have served more as a source of inspiration for modern electricity than they have actually powered anything specific. Their specialized electric organs have inspired research into soft, flexible energy sources that use layered materials to mimic certain aspects of the eel’s biology.

Some unique spas and wellness centers use non-venomous snakes as part of their massage treatments. The technique relies on the snakes’ weight and movements as they glide over the body. For some people, this can be relaxing. For others, it’s an expensive way to discover that they aren’t as calm as they thought they were.

Lin Wang was an Asian elephant who had been assigned to military transport missions during World War II in Burma. After the war, he was taken to Taiwan, where he later became a star attraction at the zoo and lived for decades. His story exudes a certain tenderness after all the hardships of war, as it is rare for animals that have experienced war to have such a peaceful end as he did. 

King Neptune was a pig from Illinois who became the mascot of the war bond campaign during World War II. Through his public appearances and symbolic auctions, he helped raise a significant amount of money for the USS Illinois.

Wojtek was a brown bear from Syria who was adopted by Polish soldiers during World War II. He became part of the unit and is remembered for helping to carry crates of ammunition during the Italian Campaign.

Canaries were used in mines because they reacted quickly to dangerous gases such as carbon monoxide. Miners took them underground to serve as an early warning system, and any sign of distress in the bird indicated that the air might be unbreathable. It’s not a pleasant thought, but their sacrifice saved the lives of many men working in extremely dangerous conditions.

During wartime, cats were used to hunt rats, particularly in the trenches of World War I, where the rodents spoiled food and spread disease. They also brought a little comfort to the soldiers in those unsanitary, frightening, and grief-stricken places. Even a semi-wild cat that slipped into a trench could be seen as a small reminder of everyday life.

Camels carried supplies and wounded soldiers during desert campaigns, where the heat, sand, and long distances made travel difficult. Some were equipped with stretcher-like supports, which made it possible to transport the wounded over terrain that was inaccessible to horses and wheeled vehicles.
