Stotting facts for kids
Imagine seeing an animal suddenly leap high into the air, lifting all four feet off the ground at the same time! This amazing jump is called stotting (also known as pronking). Animals like gazelles and springboks often do this when they spot a predator nearby. When an animal stots, its legs usually stay quite stiff. Scientists have studied this behavior to understand why these animals choose to jump in such a noticeable way, especially when they could be running away. The most popular idea is that stotting is a way for the animal to show a predator that it is strong and healthy, making it a difficult target to catch.

What Does "Stotting" Mean?
The word "stot" comes from an old Scottish and northern English word that means "to bounce" or "to walk with a bounce." You might hear someone say a ball "stots" off a wall, meaning it bounces. The word "pronking" comes from the Afrikaans language, where "pronk-" means "to show off" or "to strut." It's similar to the English word "prance," which means to walk with high, springy steps. Both words perfectly describe this unique animal jump!
Which Animals Stot?
Many different animals use stotting! You can see it in several types of deer in North America, like mule deer and Columbian black-tailed deer, especially when a predator seems very threatening. Pronghorns also stot. In Africa, many ungulates (hoofed animals) like Thomson's gazelle and springbok are known for their impressive stotting. Even the blackbuck, an animal found in India, is said to stot.
It's not just wild animals! Young domesticated animals, such as sheep and goats, sometimes stot too, though it's less common in adults.
Why Do Animals Stot? Exploring the Reasons
Stotting uses up energy and makes an animal more visible, which seems risky when a predator is around! So, there must be a good reason why animals continue to do it. Scientists have come up with several ideas:
Escaping Danger
Some people thought stotting might be a quick way to escape or jump over obstacles. However, this doesn't seem to be the main reason for animals like Thomson's gazelles. They usually don't stot if a predator is very close (less than about 40 meters away). Instead, they just run!
Another idea is that stotting helps animals living in tall grass. By leaping high, they might be trying to spot any hidden predators. This could be a way to avoid being surprised by an ambush.
Warning Others
Stotting could also be an alarm signal. When one animal stots, it might be telling other members of its herd that a predator is nearby. This warning could help the whole group stay safer. Some scientists also think that animals might stot together in a coordinated way to confuse a predator, making it harder for the predator to pick out just one animal to chase.
Showing Off Strength to Predators
Many scientists believe stotting is an "honest signal" to predators. This means the animal is truthfully showing how fit and strong it is. If an animal can jump so high and still escape, it's telling the predator, "I'm too fast and healthy for you to catch!" This benefits both the prey and the predator. The predator avoids a long, tiring chase that probably won't end in a meal. The prey avoids being chased at all.
Stotting can also signal to a predator that it has been seen. If a predator knows it has lost the element of surprise, it might give up the hunt. For example, cheetahs often give up chasing gazelles that stot. However, gazelles stot less often to African wild dogs, which are known for chasing prey relentlessly even when seen.
Just for Fun?
Sometimes, especially young animals, might stot just for play. This could be a way for them to practice their jumping and running skills, helping them prepare for adult life. While young animals do stot playfully, adult animals usually stot when a predator is present, suggesting it's more than just a game for them.
Attracting a Mate
Another idea is that stotting could be a way for animals to show off their fitness to potential mates. A strong, healthy stot might signal to other animals that they would be a good partner.
Leading evolutionary biologists, like John Maynard Smith, have suggested that stotting is a clear sign of an animal's health and its ability to escape. It's like the animal is saying, "Look how strong I am!" This signal is especially useful against predators that rely on long chases. Other experts, like C. D. Fitzgibbon, agree that it's most likely an honest way for an animal to show its condition. Tim Caro also believes that stotting tells a predator that it has been spotted.
