Introduction: A Giant from the Deep

Have you ever wondered what the largest crab in the world looks like? Imagine a creature with a leg span longer than a grown man is tall, and you’ll have a good idea of the Japanese Spider Crab. These amazing animals are the biggest crabs on Earth, and they’re full of fascinating facts that make them one of the ocean’s most interesting inhabitants.

The Size of the Japanese Spider Crab

The most incredible thing about the Japanese Spider Crab is its size. When measured from claw to claw, these crabs can be up to 12 feet long! That’s about the same length as a small car. Now, imagine trying to squeeze a crab that size into your bathtub - that would be quite a challenge! To help you picture how large these crabs can get, consider these comparisons:

  • If you stacked three average-sized adults on top of each other, they would be about the same height as the leg-span of a Japanese Spider Crab. - A Japanese Spider Crab is about as long as six bowling pins lined up end-to-end. - The body of the Japanese Spider Crab is around the same size as a basketball, but with legs that can stretch out as long as a sedan car. These crabs are seriously big! But despite their size, they’re known to be quite gentle creatures.

More about the Japanese Spider Crab

The Japanese Spider Crab is not just famous for its size, but also for its long lifespan. These crabs can live up to 100 years, making them one of the longest living creatures in the sea. They live in the waters around Japan, and they spend most of their time in very deep water, up to 600 meters below the surface. That’s about as deep as two Eiffel Towers stacked on top of each other! Despite their scary name and appearance, these crabs are actually slow-moving and peaceful. They’re also a bit of a delicacy in Japan, but because they’re so special, there are now rules to protect them from overfishing.

  • They have the largest leg-span of any arthropod. - They can weigh up to 44 pounds - that’s heavier than a medium-sized dog! - Their claws are strong enough to open shellfish but are usually used for scavenging on the ocean floor.

Conclusion

The Japanese Spider Crab is a fascinating creature that really stands out in the animal kingdom, especially because of its amazing size. Next time you see a small car, remember, there’s a crab that’s just as long! Discovering creatures like the Japanese Spider Crab helps us to appreciate the incredible diversity of life in our oceans. So, the next time you dip your toes in the sea, just think about the amazing creatures that could be living beneath the waves.

Giant Earthworm
The giant earthworm can grow up to three meters long. When baby giant earthworms hatch from their cocoons, they are only twenty centimeters long. They take five years to reach their full length. They burrow underground and make gurgling noises.
Sunflower
Did you know that the "flower" of a sunflower is not a single flower, but actually a flower head made up of thousands of small flowers? These small flowers are called florets. The florets in the center become sunflower seeds, which are currently invisible at this scale.
Wandering Albatross
The Wandering Albatross is the bird with the largest wingspan! They fly almost all the time, only stopping to eat and make babies. Their population is slowly decreasing. Now it is only at 26,000, which isn't very much.
Larger By Category

The elephant is the largest land animal. Only three species of elephants remain. They can weigh up to 8 tons, which is about 10 times the weight any human has ever achieved!
Giraffe
The giraffe is the tallest land mammal at a mind-boggling 6 meters! Its neck alone is almost half of its entire height. Adult giraffes are so tall that the only way for predators to kill them is to push them onto their side!
