If you have heard
it, you would think that it sounds like something between a
frog croak's, a chicken's clucking and something else thrown
in for good measure. In case you haven't heard it before, there
is now a site dedicated to the sound files of Carol
of CrabWorks's hermit
crab croaking . Below is just a sample.
"The land hermit
crab sometimes communicates by a whirring-chirping sound, though
not too often. These noises usually have been heard during aggressive
encounters in the crabs' natural environment and are seldom
heard in captivity. The only behavior observed that may resemble
aggression has been when one crab shakes or rocks another to
drive him from a shell the aggressor wants. Even in this act
neither crab is harmed." (Nash,
P. 1976)
"Land hermit crabs...
produce clicking sounds by intentionally tapping the shells
and rapping legs as well as make stridulating sounds by rubbing
legs together. This noise-making is used in hermit crab communication,
including aggressive displays. If a hermit crab tries to climb
onto another or makes contact with it, both crabs may stridulate
in annoyance. (Philippe
de Vosjoli, 1999)
