Pagurus perlatus, commonly known as the “pearl hermit crab”, is a species of hermit crab found in various marine environments. This crab, like all other hermit crabs, relies on empty gastropod shells for protection and shelter.
Description & Characteristics
Pagurus perlatus is characterized by its distinctive mottled coloration and smooth, pearlescent appearance. The carapace of this hermit crab can reach a maximum size of 35 millimeters, making it a relatively small species. These crabs have long, slender legs with pincers, which they use for locomotion and manipulating food. They are also known for their long, whip-like antennae.
Habitat and Occurrence
Pagurus perlatus exhibits a preference for shallow water habitats, typically residing in the intertidal zone and subtidal areas. They can be found on sandy bottoms, amongst rocks and crevices, and within seaweed beds. This adaptable species is commonly encountered in the North Atlantic Ocean, ranging from the Mediterranean Sea to the British Isles and Norway. Their distribution extends to the coasts of Portugal and France, highlighting their wide presence within the northeast Atlantic.
Taxonomy
Pagurus perlatus belongs to the family Paguridae, which encompasses a diverse array of hermit crabs. This family falls under the order Decapoda, a group that includes crabs, lobsters, and shrimp, and is further classified within the class Malacostraca, a large and diverse group of crustaceans.
Feeding
Pagurus perlatus is an omnivorous feeder, displaying opportunistic feeding habits. They primarily consume a diet of algae, detritus, and small invertebrates, including worms and mollusks. Their long antennae and pincers aid in locating and capturing food sources, allowing them to efficiently scavenge and exploit available resources.
