The term "garland crab" refers to a species of crustacean belonging to the family Inachidae, scientifically known as Liocarcinus spp. They are commonly found in coastal areas, such as estuaries and sandy shores, across the northern hemisphere, including the North Atlantic Ocean and North Pacific Ocean.
Garland crabs, also referred to as spider crabs or decorator crabs, are characterized by their striking appearance and unique behavior. They have a compact and slightly convex carapace that can vary in coloration, typically a blend of brown, green, and red hues, aiding in camouflage among seaweed and marine vegetation. Their long, slender legs are equipped with spines and setae, further assisting in the camouflage. Additionally, garland crabs possess specialized hooks and bristles on their carapace that enable them to attach various objects, such as shells, algae, or small rocks, creating an ornamental "garland" appearance for additional camouflage and protection from predators.
Feeding primarily on plant matter, detritus, and small invertebrates, these crabs are opportunistic omnivores. They use their front, pincer-like claws to grasp and manipulate food items before transferring them to their mouthparts.
Due to their unique adaptation and aesthetically appealing appearance, garland crabs have gained attention in the field of marine biology and have become popular subjects for scientific research and aquarium enthusiasts.
