Have you ever wondered how a jellyfish can sting you? Let’s dive into the fascinating world of jellyfish and find out!
Jellyfish have long, flowing tentacles that are not just for show. These tentacles are equipped with thousands of special stinging cells called cnidocytes. Jellyfish use these cells to protect themselves and to catch their food.
Each cnidocyte is like a tiny compartment that holds a small, needle-like stinger. This stinger is tightly coiled and ready to spring into action. It’s kept under high pressure, just waiting for the right moment to strike.
When something touches the jellyfish’s tentacles, it triggers the stinging cells to open. Seawater rushes in, increasing the pressure even more. This causes the stinger to shoot out incredibly fast, in less than one millionth of a second! The stinger pierces the target and injects venom, which is how a jellyfish delivers its sting.
Jellyfish sting to protect themselves from predators and to catch prey. The venom helps them immobilize their food, making it easier to eat.
Did you know that not all jellyfish stings are harmful to humans? Some jellyfish have very mild stings, while others can be quite painful. It’s always best to admire jellyfish from a safe distance!
Now you know the secret behind a jellyfish’s sting. Isn’t nature amazing?
Using craft materials like paper, string, and markers, create a model of a jellyfish. Pay special attention to the tentacles and label the parts, including the cnidocytes. This will help you visualize how jellyfish use their tentacles to sting.
Participate in a classroom simulation where you act out the process of a jellyfish sting. Use props to represent the stinging cells and demonstrate how they react when touched. This activity will help you understand the mechanics of how a jellyfish stings.
Research different types of jellyfish and their stinging capabilities. Create a poster or presentation to share your findings with the class. This will help you learn about the diversity of jellyfish and the varying effects of their stings.
Take part in an interactive quiz about jellyfish and their stinging cells. Answer questions about how the stinging process works and why jellyfish sting. This will reinforce your understanding of the topic in a fun way.
Work in groups to create a list of safety tips for avoiding jellyfish stings while swimming in the ocean. Share your tips with the class and discuss why it’s important to be cautious around jellyfish. This activity will help you apply what you’ve learned to real-life situations.

It’s AumSum Time! How does a jellyfish sting?
Jellyfish have tentacles that contain thousands of stinging cells called cnidocytes. They use these cells for protection as well as to capture prey. Cnidocytes are small compartments that house tiny, needle-like stingers. The stinger is coiled under high osmotic pressure.
When triggered by an external force, the lid of the stinging cell opens, allowing seawater to rush in. This pressure forces the stinger to shoot out, penetrate, and inject venom into the target. This discharge can occur in less than one millionth of a second.
This is how a jellyfish stings.

Jellyfish – A sea creature with a soft, jelly-like body and long, stinging tentacles. – Example sentence: The jellyfish drifted gracefully through the ocean currents.
Tentacles – Long, flexible arms that extend from the body of some sea animals, used for grabbing or stinging. – Example sentence: The octopus used its tentacles to explore the rocky seabed.
Cnidocytes – Specialized cells found in jellyfish and other cnidarians that contain stinging structures. – Example sentence: Cnidocytes help jellyfish capture their prey by releasing toxins.
Stinger – A sharp organ or part of an animal that can inject venom into another organism. – Example sentence: The bee’s stinger can cause a painful reaction if it pierces the skin.
Venom – A toxic substance produced by some animals, such as snakes and jellyfish, used to immobilize or kill prey. – Example sentence: The snake injected venom into its prey to make it easier to eat.
Predators – Animals that hunt and eat other animals for food. – Example sentence: Lions are powerful predators that hunt in groups to catch their prey.
Prey – Animals that are hunted and eaten by other animals. – Example sentence: The rabbit is a common prey for foxes in the wild.
Sting – A sharp pain or injury caused by a stinger or similar structure. – Example sentence: The sting from the jellyfish left a red mark on the swimmer’s leg.
Nature – The natural world, including plants, animals, and landscapes. – Example sentence: Scientists study nature to understand how ecosystems work.
Cells – The basic building blocks of all living organisms, which carry out essential functions. – Example sentence: Our bodies are made up of trillions of cells that work together to keep us healthy.
