what is the body structure used for protection of a crab
The crab's exoskeleton helps and supports its body. It protects the soft body of the crab. It is also waterproof, so it will protect it underwater, too.

The spine.
where is the support in a frame structure
A shell structure supports its self and a frame structure does not support it self.
number one the water is able to give enough support to a life form as long as it is surrounding the the animal.Ex. Jellyfish Number two the hard shell with other stuff STUFFED inside also provides enough support
No, crab shells are not made of bone; they are composed of chitin, a tough, flexible polysaccharide, and are often reinforced with calcium carbonate. This material provides strength and protection to the crab's body. Unlike bones, which are part of the vertebrate skeletal system, crab shells are part of an exoskeleton that supports and encases the animal from the outside.
The pelvis is the bowl-shaped structure that supports the spine.
