I know jellies have a hydroskeleton, and spiders actually use hydraulics* to extend their legs**. Both of those would use liquid water. *think pressurizing a garden hose **the legs contract with another mechanism (and that's why the legs curl when they dry out)
I think pufferfish would puff up with water as well. Plants are kind of hydroskeletal - they go limp when they dry out.
I guess hydroskeletons and musculoskeletons (?) are good for flexibiliy (and storing extra water), but the osseous/hard skeletons make better armor/weapons.
