Crabs Who Carry Their Houses!

Hermit crabs are super special because they don't grow their own hard shells. Instead, their tummies are soft and squishy! To stay safe from hungry animals, they find empty snail shells to live in.

It's like they're always moving house! They have ten legs, but two are used for walking and the other two are strong claws for grabbing food and defending themselves. They are like tiny knights with their shell armor!

Where Do These Shell-Wearers Live?

You can find hermit crabs in lots of places near the ocean! They love to explore sandy beaches and rocky shores. Some hermit crabs even live deep in the ocean where it's dark and mysterious. They are found all over the world, from warm tropical waters to cooler seas. They need to be near the water to keep their gills wet so they can breathe, just like you need air!

What's for Dinner for a Hermit Crab?

Hermit crabs are not picky eaters! They are omnivores, which means they eat both plants and animals. They love to scavenge, which means they look for food that's already dead, like tiny bits of fish or other sea creatures. They also munch on algae, which is like seaweed. Their strong claws help them to pick up food and bring it to their mouths. They help keep the beach clean by eating leftovers!

Finding a New Home!

When a hermit crab gets too big for its shell, it has to find a new one. This is a very important job! They will look for an empty shell that fits just right. Sometimes, they have to wait for another snail to leave its home. If they can't find a shell quickly, they are very vulnerable. They might even trade shells with other hermit crabs if they find a better fit!
