Beach crawlers are a type of crustacean, commonly known as CRABS. They are found in many coastal areas around the world, and are often seen scuttling along the shoreline. They have two sets of antennae, four pairs of legs, and a hard exoskeleton. Beach crawlers are omnivorous, feeding on both plant and animal matter. They are an important part of the marine food chain, providing food for larger predators such as fish and birds.
