Coenobita purpureus Behavior

When they feel threatened, they retreat into their shells and close their legs tightly, or they scratch their shells with their legs, making a creaking sound to intimidate.

Coenobita purpureus Found Locations
Chichijima, Ogasawara Islands
Discovered at Kominato Coast on Chichijima, Ogasawara Islands. While searching in the forest leading to the coast after hearing a rustling sound, I found a Coenobita violascens walking. I chased it to the beach to observe it closely, but it became wary and retreated into its shell. After about 10 minutes of silence, it opened its closed legs just a little.
There seem to be a certain number of land hermit crabs in the forest near the coast, and if you are quiet, you can hear the sound of them crawling on the ground.
