This large hermit crab lives on sandy and muddy bottoms at depths of 20 to 200 meters. It is characterized by horizontal stripes on its claws and legs. It lives inside shells such as the staghorn clam, and sometimes has anemones attached to its shell to protect it from predators such as octopuses.
Collaborative commentary between Ibaraki Robots players and living creatures
The exhibition tanks inside the museum will have explanatory boards about the collaboration between Ibaraki Robots players and living creatures. You can enjoy the unique exhibits of this collaboration event, where you can compare and experience the characteristics of the creatures, such as their jumping power and arm length, together with the players! You will have to wait until you visit to find out which player will be collaborating with which exhibition tank, so be sure to explore the museum while looking for the explanatory boards.
