Description

 Pagurus cuanensis is herpale red-brown in colour with darker and some white spots. Its legs are predominantly red. The carapace can grow to lengths of 1.5 cm. This hermit crab has a larger right pincer, about 7 mm in length. The upper area of the right pincer is strongly covered in hair, forming a matted fur, and is also covered in conical teeth, which are more developed in the mid-line. All the visible parts of the crab are very hairy. Long narrow eye-stalks with slightly expanded cornea nearly reach the end of the second segment of the antennule. The section of the carapace located between the eyes is rounded. The 5th and 6th segments of the right pincer are of equal length.
