The difference between being on land and being in water is the degree
of damping.
Measurements, on land show that several, perhaps all segments of a
limb are potentially resonant.
When free to move they have a resonant frequencies which can be
measured with comparatively simple apparatus (middle level technology
anyway). The are not however highly resonant, the Q typically being
between the values of about 2 & 4.
In the water the damping will be increased and I would expect the
limbs to be no longer resonant, being either critically damped or more
likely, over damped.
I am not referring to the wetting !
