Have you ever seen a soldier crab? I have! They are round and light blue, and about the size of a quarter. They swarm together in huge armies of hundreds of crabs. But when you come near, they all dig into the sand, turning like a corkscrew. When they scurry, they go fast. Real fast! When they move, they pick up sand and suck the food out of it. Then the crabs poop it out in sand pellets.
Soldier crabs live on beaches of Australia and other South Pacific islands. I feel very lucky to have seen them. They are amazing!There is a cool youtube video showing a "battle of the soldier crabs". Check it out! www.youtube.com/watch?v=cWM8K4YShc0
