Crab and it's lifecycle

Crabs are marine or freshwater crustaceans belonging to the order Decapoda, characterized by their short bodies, 10 limbs (including pincers), and a hard exoskeleton. They are found in diverse habitats, from oceans and rivers to mangroves and sandy beaches. Crabs play important roles in their ecosystems as scavengers and as a food source for various animals.
There are over 6,800 species of crabs, with varying adaptations, sizes, and behaviors. Some common types include the blue crab, king crab, and Dungeness crab. Crabs exhibit fascinating behaviors, such as burrowing, molting (shedding their exoskeleton), and complex social interactions. They are also economically significant, being a popular seafood choice in many cultures.
