Is it okay if your hermit crabs chirp?

Why do hermit crabs chirp?

• Does a chirping hermit crab mean they are happy, sad, angry, want attention, scared, communication, etc?

• Answer:

  Apparently, the hermit crabs from Ecuador do this more than the Caribbean species. It is known as "stridulation", rubbing body parts against another body part or shell to make the noise. From what I have researched it seems that it is most likely a communication and "Hey, don't disturb me!" signal. Other animals, (ex: tarantulas, crickets, katydids,etc.) are well known for their stridulating. In their cases it is used as a breeding, territorial, disturbed and defense mechanism. Good question! I'd never heard it until I clicked on the link. Way cool. :)
