The Hairy Clinging Crab (Amphithrax pilosus) is a species of crab found in the Indo-Pacific region. It is a common sight in various marine habitats, showcasing its adaptability to different environments.
Description & Characteristics
The Amphithrax pilosus is characterized by its hairy carapace, which is a prominent feature that gives it its common name. Its body is typically a reddish-brown color, although it can vary in shade depending on its environment and diet. This crab is relatively small, reaching a maximum size of about 5 centimeters in width. Its legs are covered in fine hairs, providing additional grip as it navigates its rocky and coral environments.
Habitat and Occurrence
Amphithrax pilosus is a common inhabitant of the intertidal zone and shallow subtidal regions of the Indo-Pacific. This species can be found in a variety of habitats, including rocky shores, coral reefs, and mangrove forests. They typically reside in depths ranging from the surface to around 20 meters. As a result, this species is commonly found in the Neritic Zone, which is the shallow area of the ocean that extends from the shoreline to the edge of the continental shelf.
Taxonomy
Amphithrax pilosus belongs to the family Mithracidae, a diverse group of crabs known for their often-spiny carapaces. This family is part of the Order Decapoda, which includes a vast array of crabs, lobsters, and shrimp. Decapoda, in turn, belongs to the Class Malacostraca, the largest group within the crustacean class. This hierarchical classification highlights the evolutionary relationships and shared characteristics among these diverse marine creatures.
Feeding
The Hairy Clinging Crab (Amphithrax pilosus) is an omnivore, feeding on a variety of food sources. Its diet primarily consists of algae, but it also scavenges on carrion and occasionally preys on small snails. This opportunistic feeding strategy allows it to thrive in its diverse and often-competitive habitat.
