Quck answer
Ants are incredibly diverse creatures, with over 12,000 known species. This diversity is reflected in their physical characteristics, including leg length. Recent research has shown that some species of ants have evolved tiny stilts on their legs, which allow them to walk over uneven terrain without getting stuck. Other species have amputated legs that allow them to move more quickly in confined spaces. This diversity in leg length and structure is an adaptation to the specific environments in which these ants live and move. Understanding these adaptations can help us better understand the complex and fascinating world of ants.
Wild Animals
Scientists have discovered that desert ants use a built-in step integrator to calculate the distance to their home. They accomplish this even though they do not have the benefit of landmarks in the desert to guide them. Nick Bos, an ant researcher at the University of Helsinki, explains that the shifting sands keep wiping away all the chemical trails, leaving no way to navigate by chemicals. In 2006, a team of scientists from the University of Ulm in Germany and the University of Zurich in Switzerland conducted experiments on Saharan desert ants (Cataglyphis fortis) to understand their navigation abilities. Using pig hair to fashion stilts for the ants’ legs, they discovered that the ants overshot their intended destination when they returned to the ground. This led the scientists to conclude that the ants must be using a natural odometer to calculate how many steps they need to take to get home.В
Scientists used pig-hair bristles as stilts for ants to investigate how the ants know where their nest after leaving it.

To test this theory, scientists partially amputated the legs of other desert ants, forcing them to take smaller steps. The ants with shorter legs seemed to perceive too early that they’d reached the place where their nest should be when, in fact, they still had a distance to go. This confirmed the scientist’s hypothesis that the desert ants use a built-in step integrator to calculate the distance to their home.В
Now That’s Cool
Saharan desert ants can withstand an internal temperature that reaches 131 degrees F (55 degrees C), a temperature that would cook most animals’ insides.
FAQ
1. What are tiny stilts for ants?
Tiny stilts are artificial legs that are attached to ants to study their behavior and walking patterns. These stilts are made of glass or plastic and are about ten times the length of the ant’s original legs.
2. Why do scientists use tiny stilts for ants?
Scientists use tiny stilts for ants to understand how the ant’s leg length affects its walking behavior. This helps them to understand how ants move around in their natural habitats and how they adapt to different environments.
3. How do scientists attach tiny stilts to ants?
Scientists attach tiny stilts to ants using a special glue that is safe for the ants. The glue is applied to the ant’s legs, and the stilts are then attached to the glue. The stilts are designed to be lightweight and not interfere with the ant’s natural movements.
4. What do scientists learn from studying ants with tiny stilts?
Scientists learn how the length of an ant’s legs affects its movement, speed, and ability to navigate through different environments. They also learn how ants adapt to different terrains and overcome obstacles.
5. Why do some ants have amputated legs?
Some ants have amputated legs as a form of punishment within their colonies. These ants may have broken a rule or failed to complete a task, and their legs are amputated as a form of discipline. The loss of legs also makes it more difficult for the ant to move around and perform tasks.
6. Do ants with amputated legs survive?
Ants with amputated legs can survive, but their survival rate is lower than that of ants with all their legs. The loss of legs can make it more difficult for the ant to find food, defend itself, and escape from predators. However, ants are highly adaptable and can compensate for the loss of legs by using their remaining legs more efficiently.
7. Can ants regrow their amputated legs?
No, ants cannot regrow their amputated legs. Once a leg is amputated, it is gone for good. However, some species of ants can regenerate lost limbs during their larval stage.
8. How do ants communicate with each other?
Ants communicate with each other using a variety of methods, including chemical signals, sound, and touch. They use pheromones to leave trails for other ants to follow, and they also use sound and touch to convey information about the location of food and other resources.
9. How many legs do ants have?
Most ants have six legs. However, some species of ants have more or fewer legs, depending on their specific needs and adaptations to their environment.
10. What is the purpose of an ant’s legs?
The purpose of an ant’s legs is to help it move around and perform tasks, such as finding food, defending the colony, and caring for the young. Ants also use their legs to communicate with each other and navigate through their environments.
11. What is the lifespan of an ant?
The lifespan of an ant depends on its species and its role within the colony. Worker ants typically live for several months to a few years, while queen ants can live for several decades. Male ants, which are only produced during mating season, typically live for only a few weeks.
