    I have a pet crab who until very recently has been pretty quiet. A few weeks ago I heard quite a loud sound like grinding teeth; only to discover it was the crab! Does anyone know why he is doing that noise? Thanks in advance.

    They do that when they are threatened, most likely something startled it. No need to be alarmed.
