Crab : The Curious World of Crabs: A Peek Beneath the Shell
Crabs: The Iconic Crustacean
Crabs are decapods, meaning they have ten legs. These belong to a group of animals called crustaceans, which includes lobsters and shrimp. With over 6,800 species of crabs worldwide, they come in various shapes, sizes, and colors. Their hard shells (exoskeletons) act as armor, protecting them from predators and rough environments.
Despite their tough exterior, crabs are surprisingly diverse. From the tiny pea crab that fits on your fingernail to the enormous Japanese spider crab with legs over 12 feet long, they never fail to surprise us.
Why Do Crabs Walk Sideways?
One of the quirkiest things about crabs is their sideways shuffle. This isn’t a weird dance move; it’s because their legs are jointed in a way that makes sideways movement more efficient. Plus, it gives them a unique flair that distinguishes them from other marine creatures.
