The pea crab is the smallest crab, measuring from 0.27 to 0.47 inches long, while the Japanese Spider crab is the biggest crab, measuring about 18 feet from claw to claw. On the other hand, Horseshoe crabs are not classified as crabs, they are actually closer to spiders and scorpions. A small boxer crab uses anemone to protect their claws. Some crabs live in crazy places. Some live in smoking volcanic vents in the ocean, thousands of feet below the surface. Some even live in trees and under ice in Antarctica!
