THREE MARINE PROJECTS
This species has chelipeds (the large claws) covered in small granules or small teeth. The propodus* part of right chela has two rows of larger granulations, starting at the base and converging towards the middle. This can (just about) be seen in photo (top right). Other Pagurus species seem to have more hairy claws and legs and lack these 2 rows of granulations. *To see a diagram of the parts look at this site
