@unsulliedfact: Crabs are among the most diverse crustaceans on Earth, with more than 7,000 known species living in oceans, freshwater habitats, and even on land. From the enormous Japanese Spider Crab with the longest leg span of any crab to the powerful Coconut Crab and the brilliantly colored Sally Lightfoot Crab, each species has evolved unique adaptations for its environment. Some climb trees, others hide among coral reefs, while many spend their lives patrolling sandy shores and rocky coastlines. Their extraordinary variety in size, color, claws, and body shape proves that even within a single group of animals, nature can produce an incredible range of forms.
