Rock Pool Habitats
Explore rock pools (tide pools) as small ocean habitats where crabs, anemones, starfish, and small fish can be found, and understand that these creatures are adapted to survive crashing waves and changing water levels
What a learner can do afterwards
- Name at least three creatures found in rock pools
- Describe a rock pool as a small ocean habitat on the shore
- Explain one way rock pool animals cope with waves or changing water levels

A rock pool is a small pool on the beach. The sea leaves it behind when the tide goes out. Crabs, starfish, and small fish live inside it.
Mia peeks into a rock pool at low tide. She spots a crab hiding under a rock. She counts three starfish stuck tight nearby. A tiny fish darts between the plants.
Waves crash into rock pools all day long. Crabs and starfish grip the rocks tightly. Some fish hide in dark cracks to stay safe.
Rock pools are tiny ocean homes where animals hold on tight or hide from crashing waves.

How to Draw a Starfish
A starfish is also called a sea star. It lives underwater, even in rock pools by the beach. Starfish come in many colors, like red, orange, and blue. A starfish has a small middle part and five arms that stick out, just like a star shape.
If you want to draw a starfish, start with a tiny dot in the middle of your paper. Then draw five lines going out from that dot, like the points of a star. Those lines become the starfish's arms. Add a rounded bumpy shape around each arm to make it look real.
Next time you visit a rock pool, look closely at the rocks and the shallow water. You might spot a real starfish holding on tight so the waves do not wash it away.
Prawns in Tide Pools
Prawns are little sea animals that look like small lobsters. They live in shallow water near the shore. Prawns love tide pools and bays, the same kind of small pools you find between rocks at the beach.
Prawns follow the tide. When the tide comes in, fresh sea water fills the rock pools and brings prawns and other tiny creatures with it. When the tide goes out, prawns hide under rocks or in seaweed so they do not dry out.
Prawns are usually orange-red, just like the tiny shrimp you might see darting around in a rock pool.
How Sand Crabs Live
Sand crabs live right where the ocean water meets the shore. They dig little burrows and hide in them. Sand crabs are saltwater animals, just like the crabs you might find in a rock pool.
Sand crabs do not go looking far for food. They wait for the waves to bring tiny bits of food to them. This is a smart way to eat without fighting the waves too hard.
Crabs like these are good at handling crashing waves. They tuck down low and hold on tight so the water does not carry them away. That is one reason crabs can live in busy places like rock pools, where waves crash again and again.
Homes Where Water Levels Change
An estuary is a place where a river meets the sea. Just like a rock pool, it is a special habitat where the water level keeps changing. Sometimes it is full of water, and sometimes the water goes down low.
Animals that live in places like this are used to the changes. Some hide under rocks when the water is low. Others hold on tightly to rocks so they do not get swept away when waves crash in.
These small habitats are important homes for many sea creatures. We can help by keeping the water clean and leaving rocks, shells, and animals in their homes.
