Crabs

Marine crabs are diverse crustaceans found in oceans worldwide, inhabiting a range of habitats from rocky shores and coral reefs to sandy bottoms and deep sea vents. They are characterized by their robust bodies, jointed limbs, and typically sideways-walking motion. Marine crabs come in various sizes and colors, often adorned with defensive features like spines or camouflage patterns. They play vital ecological roles as scavengers and predators, feeding on organic matter and helping maintain ecosystem balance.
