Alaska is home to some of the most fascinating crabs in the world, and learning to identify them is a fun way for kids to explore nature. This list helps children recognize seven common types of Alaska crabs by their special features, colors, and sizes. Each crab has unique traits that make it interesting and important to Alaska’s ocean life.
1. Red King Crab
The Red King Crab is one of the largest and most famous crabs in Alaska. It can have a leg span of up to 6 feet, with a reddish-orange shell covered in spines. Kids can spot it by its big claws and the five points on each side of its shell. These crabs live on the ocean floor and are popular for their tasty meat.
2. Blue King Crab
The Blue King Crab is less common than the Red King Crab and has a blue or purple shell that turns red when cooked. It’s smaller than the Red King Crab but still has large claws. It lives in colder, deeper waters around Alaska and has a smoother shell without many spines, making it easier to tell apart.
3. Tanner Crab (Snow Crab)
Tanner Crabs, often called Snow Crabs, have long, thin legs and a light brown or tan shell. They are smaller than king crabs but move quickly across the ocean floor. Kids can recognize them by their smooth shell and the way their legs look like snowflake arms. These crabs are also a favorite for seafood lovers.
4. Dungeness Crab
Dungeness Crabs have a wide, smooth shell that is reddish-brown and can grow up to 10 inches wide. They have strong claws and live along Alaska’s southern coast. These crabs are important to both the ocean ecosystem and local fishermen because they taste sweet and are easy to catch.
5. Hairy Crab
The Hairy Crab has a round shell covered with short, thick hairs that help it blend into rocky ocean bottoms. Its shell color can be brown or greenish. Kids might notice the fuzzy look compared to other smooth-shelled crabs. These crabs are smaller and less known but play a key role in keeping the ocean floor clean.
6. Spot Prawn Crab
Spot Prawn Crabs are tiny compared to king crabs and have a smooth, brownish shell with spots on their legs. They often live near underwater plants and rocks. Their small size and spotted legs make them easy for kids to identify when exploring tide pools or shallow waters.
7. Box Crab
Box Crabs have a unique square-shaped shell that looks like a box, which helps protect them from predators. Their shell is usually light brown with some darker spots, and they have strong claws to dig into the sand. Kids can find them hiding under rocks or burying themselves in the sand along Alaska’s beaches.
How to Choose
When identifying Alaska crabs, kids should focus on a few key features: shell color and texture, claw size, leg shape, and habitat. For example, the Red King Crab’s spiny shell and large size stand out, while the Tanner Crab’s long thin legs are easy to spot. Knowing where the crab lives also helps; some crabs prefer deep ocean floors, while others hide in tide pools or sandy beaches. Learning these details makes it easier to tell one crab from another and appreciate their differences.
Frequently Asked Questions
Q: Are all Alaska crabs safe to touch?
Most crabs are safe to touch gently, but some can pinch if scared. It’s best to watch without grabbing, especially if you’re not sure which crab it is.
Q: Why do some crabs have hairy shells?
Hairy shells help crabs camouflage by blending into rocky or sandy ocean floors, protecting them from predators.
Q: What do Alaska crabs eat?
Alaska crabs eat a variety of things like small fish, clams, algae, and dead animals on the ocean floor.
Q: How do crabs grow so big like the Red King Crab?
Crabs grow by molting, which means they shed their old shell and form a new, bigger one. This allows them to increase in size over time.
Q: Can kids eat Alaska crabs?
Yes, Alaska crabs like the Red King and Tanner are delicious and safe to eat when cooked properly, but they must be prepared by adults.
Q: Why do some crabs have different colors?
Crab colors come from their shells and help them blend in with their environment or warn predators. Some colors change when cooked, like the Blue King Crab turning red.
Final Thoughts

Each crab has special features that make it unique, from the giant Red King Crab to the tiny Spot Prawn Crab. By paying attention to color, size, and habitat, kids can become little crab experts and enjoy exploring Alaska’s coastal waters safely and respectfully.
