There are many great crafts and activities to learn about echinoderms for kids. Also, look at my page Oceans Unit Study and Lapbook.
Have you ever wondered about the incredible creatures that live in the big, blue ocean? Well, let’s dive into the fascinating world of echinoderms.
Echinoderms are a group of sea animals that have some really unique features, setting them apart from all other life in the ocean.
Echinoderms are marine animals, meaning they spend their entire lives in saltwater environments.
They can be found in all sorts of ocean habitats, from shallow tide pools to the deepest parts of the sea.
The name “echinoderm” comes from Greek words that mean “spiny skin.”
Many echinoderms, like sea urchins, have a tough outer layer that can be covered in bumps, plates, or even sharp spines.
BOOKS FOR KIDS ABOUT ECHINODERMS
These spines can be used for protection against predators, helping them stay safe in the ocean. Even those that don’t have obvious spines often have hard, bumpy skin.
Next, look at some books about echinoderms.

Next, look at these facts about echinoderms for kids.
FACTS ABOUT ECHINODERMS FOR KIDS
Most animals, including humans, have what’s called bilateral symmetry. This means if you draw a line down the middle of our body, the left and right sides are pretty much mirror images of each other.
But echinoderms are different! Most of them have radial symmetry as adults. Imagine a bicycle wheel: all the parts radiate out from a central point.
That’s how an adult starfish or sea urchin is structured. They often have five or more arms or sections arranged around their middle. Baby echinoderms actually start out with bilateral symmetry and then develop radial symmetry as they grow up.
Echinoderms have a fascinating way of moving using tiny structures called tube feet. These are small, flexible, hollow appendages that are usually found on the underside of their arms or body. They are part of a special system called the water vascular system.
This system is a network of canals filled with seawater. Echinoderms can control the water pressure in these canals, which allows them to extend and retract their tube feet. These little feet act like suction cups, helping the animals to grip onto surfaces, crawl along the seabed, and hold onto their food.
ECHINODERMS FACTS FOR KIDS
Echinoderms don’t have a brain like we do. Instead, they have a simpler nervous system. They usually have a nerve ring that circles their mouth and radial nerves that extend out into each of their arms or along their body.
This network of nerves helps them sense their environment, detect food, and coordinate their movements.
Some echinoderms have an amazing ability called regeneration. This means they can regrow lost or damaged body parts! Starfish are famous for this.
If a starfish loses an arm, it can often grow a completely new one. In some cases, if a piece of a starfish arm breaks off along with a part of the central disc (the middle part), that piece can even grow into a whole new starfish!
TYPES OF ECHINODERMS
- Starfish- Probably the most recognizable echinoderms. They typically have five arms radiating from a central disc, but some species can have many more.
They use their tube feet on the underside of their arms to slowly crawl along rocks and the seafloor.
Starfish are often predators, feeding on things like clams and mussels by using their strong arms to pry open the shells and then pushing their stomach out to digest the soft part.
Here is a super fun and Free Summer Unit Study For Kids and Fun Starfish Craft to try.
These Butterscotch Crunch Starfish look delicious.
- Sea urchins- Round or oval-shaped and are covered in spines of different lengths and thicknesses. These spines provide protection and can sometimes even be venomous. Sea urchins mostly eat algae and other small bits of organic matter.
They have a special mouth on their underside with five teeth that they use to scrape food off surfaces. You can find sea urchins in various colors, from black and brown to purple and red.

- Sea cucumbers- Have long, soft, and leathery bodies, making them look quite different from other echinoderms. They move slowly along the ocean floor using their tube feet and sometimes by wiggling their bodies.
Sea cucumbers are important scavengers, meaning they eat tiny particles of food and organic matter that they find in the sediment.
Some sea cucumbers can even eject parts of their internal organs as a defense mechanism, and then regenerate those parts later!
For an art project you can learn How to Draw a Sea Cucumber.
- Sand dollars- are flat, round echinoderms that live on sandy bottoms in shallow coastal areas. They are often found partially or completely buried in the sand.
ECHINODERMS FOR KIDS
They have tiny spines and tube feet on their upper and lower surfaces that help them move and collect food particles from the sand. The beautiful patterns you often see on the shells of dead sand dollars are made up of the arrangement of their skeletal plates.
Paper plates sand dollars are easy and a great way to learn about the features of starfish. Look at my post Fascinating Life Cycle Of A Sand Dollar & Hydro Dipped Craft.
Use these shells, starfish, and sand dollars to create sensory bins, dioramas, or add to the science shelf for exploration.
- Brittle stars- look a bit like starfish, but their arms are much longer, thinner, and more flexible. They move much more quickly than starfish by using snake-like movements of their arms.
Unlike starfish, their arms are quite brittle and can easily break off if they are threatened.
However, just like starfish, they can regenerate lost arms. Brittle stars are very common in many marine habitats and can be found hiding under rocks or in crevices.
Ocean Anatomy is a wonderful resource to learn about all echinoderms including the brittle sea star.
Finally, look at how to make simple sea urchin craft.
HOW TO MAKE A SIMPLE SEA URCHIN CRAFT
You will need:
- Foam balls
- Toothpicks
- Craft paint
- Craft glue
First, if you can only find round styrofoam balls instead of the half use a knife to carefully slice them in half.
Paint your styrofoam half whatever color you desire and set it aside.
For younger learners skip this step and focus on the outside.
The quickest way I found to paint all the toothpicks is to put some paint in a bowl with a little water to thin it out and roll them around in the watered-down paint.
You will need a lot of toothpicks to make a nice full sea urchin.
Shake off the excess (wear gloves to avoid painted fingertips) and press the toothpicks into the styrofoam ball.
You can use a paintbrush to add a little more color to give it depth and contrast, we did white tips to create the Pacific Purple Sea Urchin.
Allow to dry completely.
