Fun Facts About Northern Crabs (for a 6-year-old)
Hi! Let’s learn about crabs that live in cold northern oceans. These are easy and fun facts you can remember.
1. Where they live
Northern crabs live in cold seas near places like Alaska, Canada, and the north parts of the ocean. Some live under rocks at the beach. Some live deep in the water.
2. What they look like
- They have a hard shell like a suit of armor to protect them.
- They have 10 legs: 8 walking legs and 2 claws (so they are called "ten-footed").
- Colors can be red, orange, brown, or white.
3. How they move
Crabs usually walk sideways. Their legs are shaped so it is easy for them to move sideways quickly. Try walking a little to the side like a crab — it’s silly and fun!
4. What they eat
Crabs eat lots of things: small fish, worms, plants called algae, and bits of food they find on the sea floor.
5. How they grow
Crabs grow by shedding their old shell. This is called molting. After they drop the old shell, they hide until the new shell gets hard.
6. How they breathe
Crabs have gills like fish. Their gills need to stay wet, so crabs stay in the water or in wet places.
7. Big and small crabs
Some northern crabs are small, and some are very big with long legs (like king crabs). There is also a crab called the snow crab that lives in cold water and has long legs.
8. Staying safe
- Crabs can pinch with their claws, so don’t touch wild crabs.
- If you visit the beach, look at crabs with your eyes — or ask an adult to help.
Try this! (A fun activity)
- Draw a crab: make a round body, two big claws, and 8 legs.
- Color it red, orange, or brown.
- Practice walking like a crab: take sideways steps and wiggle your fingers like claws.
