While we often admire the beauty of wildlife, it’s important to remember that nature can be quite fierce. Many animals have sharp teeth and claws designed for hunting, and some even have venomous bites. When we think of projectiles, we usually imagine human-made weapons. However, some animals and even plants have developed their own unique ways to launch projectiles for survival.
In the wild, survival is a constant challenge, and some species have evolved fascinating projectile abilities. For example, certain beetles can unleash a spray of toxic chemicals, some fish can shoot water at their prey with incredible precision, and even mushrooms can launch their spores at high speeds.
There are hundreds of creatures that use projectiles for hunting, defense, or reproduction. These adaptations have intrigued scientists and nature enthusiasts for many years.
Earth is home to over 400,000 species of beetles, and many of them face threats from predators like frogs, birds, and other insects. To protect themselves, some beetles have developed amazing defense mechanisms. One such beetle is the Bombardier beetle, which can spray boiling hot chemicals at its enemies.
When threatened, Bombardier beetles mix two chemicals inside their bodies, causing a reaction that heats the liquid and shoots it out in rapid bursts. This spray can be directed in different directions, even over the beetle’s back. Remarkably, these beetles are unharmed by their own chemical weapons. Some can even survive being eaten by toads, only to be expelled after causing an explosion inside the toad’s stomach!
Not all animal projectiles are chemical. Some animals, like the archerfish, are known for their incredible accuracy. Archerfish can shoot jets of water at insects up to three meters above them, hitting their targets with perfect precision. They have special mouth structures that help them focus the water, and they can predict where their prey will be before shooting.
Archerfish are also smart enough to recognize different targets and even distinguish between human faces. They learn from each other and improve their shooting skills over time, showcasing their impressive intelligence.
Projectiles aren’t limited to animals. Some fungi, like the artillery fungus and dung cannon fungus, have developed ways to launch their spores at incredible speeds. They use fluid and osmotic pressure to propel their spores, demonstrating nature’s creativity in spreading life.
While humans often pride themselves on their inventions, the natural world is full of remarkable strategies for survival and adaptation. From beetles and fish to fungi, nature has its own ways of using projectiles to thrive.
If you’re curious about how these creatures achieve such accuracy, there are courses available that explain the science behind it. Learning about these natural wonders can be both fun and educational, offering insights into the amazing world around us.
Use craft materials to build a model of a Bombardier beetle. Focus on its unique defense mechanism. Explain how the beetle mixes chemicals to create a hot spray. Present your model to the class, highlighting the beetle’s ability to direct its spray in different directions.
Simulate the archerfish’s hunting technique by using a water gun to hit targets placed at different heights. Measure your accuracy and discuss how the archerfish’s mouth structure helps it achieve precision. Reflect on how learning and practice improve your aim, just like the archerfish.
Conduct an experiment to demonstrate how fungi launch their spores. Use a balloon to simulate the build-up of pressure and release it to propel a small object. Discuss how fluid and osmotic pressure work in fungi and compare it to your experiment.
Choose an animal or plant with a unique projectile mechanism. Research how it uses projectiles for survival. Create a presentation to share your findings with the class, including visuals and interesting facts about the species’ adaptations.
Participate in a debate about which animal or plant has the most effective projectile mechanism. Form teams and argue for your chosen species, using evidence from your research. Discuss the evolutionary advantages of these adaptations and what makes them fascinating.

No matter how much we may love wildlife, the natural world is undeniably violent. The sharp teeth and claws of carnivores are made to tear through flesh, and venomous fangs unleash deadly toxins. However, when we think of dangerous projectiles, we often think of human conflict. Humans are the only animals with the ability to throw an object and kill a target, making projectile use by other organisms rare.
Yet, it is not unheard of, as the battle for survival is indeed a battle. Nature is endlessly inventive, and some species have evolved their own version of ballistics. Certain beetles can release a barrage of toxic chemicals, some fish can shoot prey out of the air with remarkable accuracy, and even mushrooms can send their spores flying at incredible speeds.
There are hundreds of creatures that have projectiles in their arsenal, whether for hunting, self-defense, or procreation. These organisms have been sources of wonder and fascination for centuries.
Earth is home to more than 400,000 species of beetles, which can be preyed upon by various animals, including frogs, toads, shrews, birds, and even other insects. This multitude of predators has led beetles to evolve incredible defense mechanisms. Charles Darwin experienced this firsthand in 1846 when he was hunting for different beetle species. While he was already holding two beetles, he spotted a third but couldn’t let go of the ones he had. In a moment of desperation, he gently seized one of the beetles between his teeth, only to be met with a painful surprise as the beetle squirted acid down his throat.
Chemical defenses like the one Darwin encountered are key to more than 500 species collectively known as Bombardier beetles. These beetles rely on toxic chemicals and trigger a chemical reaction within their bodies that superheats the fluid, causing it to explode out. Some species can even aim their spray in various directions, including over their own backs.
When threatened, Bombardier beetles mix two volatile liquids, triggering an intense chemical reaction that ejects boiling hot spray in rapid pulses. Remarkably, they sustain no damage from the toxic chemicals or the explosive reaction. Research has shown that Bombardier beetles can survive being swallowed by toads, with some species being expelled after the toads experienced an explosion in their stomachs.
Not all projectiles in the animal kingdom are chemical. Some animals are incredibly accurate with their shots, rivaling human sharpshooters. For example, archerfish have the remarkable ability to shoot jets of water at prey up to three meters above them, achieving 100% accuracy in lab settings. They have special mouth and tongue structures that help focus the water, and they can calculate where their prey will be before shooting.
Archerfish can also distinguish between different targets and even recognize specific human faces, showcasing their impressive cognitive abilities. They rely on social learning to improve their shooting skills over time, becoming better at aiming with experience.
Interestingly, projectile use is not limited to animals. Certain fungi, like the artillery fungus and dung cannon fungus, have mastered the art of high-speed motion to disperse their spores. These fungi utilize fluid pressure and osmotic pressure to eject their spores at incredible speeds, demonstrating nature’s ingenuity.
While humans often think of themselves as the most inventive species, the natural world has its own remarkable strategies for survival and adaptation.
To better understand the mechanics behind accurate target shooting, I took a course on Brilliant.org, which provided in-depth explanations and interactive lessons.
