Anapagurus hendersoni is a species of hermit crab belonging to the family Paguridae. This crab, like all hermit crabs, relies on the empty shells of other marine organisms for protection. The species is distinguished by its characteristic coloration and size, which can reach a maximum of around 45 millimeters in length.
Description & Characteristics
Anapagurus hendersoni has a distinctive orange-brown coloration with a series of white spots running along its carapace. The chelipeds, or claws, are robust and of moderate size. This species is characterized by its asymmetrical abdomen, a common feature in hermit crabs, allowing it to fit snugly into the gastropod shells it uses as shelter. The abdomen is soft and vulnerable, making the use of a shell crucial for the crab’s survival.
Habitat and Occurrence
Anapagurus hendersoni is a predominantly shallow-water species, typically found in depths ranging from the intertidal zone down to around 100 meters. Its habitat preference leans towards rocky reefs and coastal environments. Its distribution extends across a significant portion of the North Atlantic Ocean. Anapagurus hendersoni is a common sight in the northeastern Atlantic, including the waters off the coasts of Europe, as well as the North Sea, and the English Channel. This species is also found in the Mediterranean Sea, making it a prevalent presence in these aquatic ecosystems.
Taxonomy
Anapagurus hendersoni belongs to the Class Malacostraca, which encompasses a wide variety of crustaceans. Within this class, it falls under the Order Decapoda, which includes all the familiar crabs, lobsters, shrimp, and crayfish. Finally, it is categorized under the Family Paguridae, which comprises the hermit crabs.
Feeding
Anapagurus hendersoni is an opportunistic scavenger. Its diet primarily consists of detritus, decaying organic matter, and algae. It is also known to prey on small invertebrates, including worms and other crustaceans. As a scavenger, Anapagurus hendersoni plays a vital role in the marine ecosystem by breaking down and consuming organic debris, contributing to nutrient cycling and maintaining the health of the benthic environment.
