Nope. That wouldn't be Eupagurus bernhardus. Eupagurus bernhardus is the common hermit crab, known for hiding in their shells. Hermit crabs have soft nether regions. The creature pictured has its own carapace, including a tail, shedding that carapace during its growth cycles.
Hint: I've already given one name for this particular crustacean,a nd it's on this page at least 3 times. I will accept that name, or several other names that it is commonly known by.
