Jellyfish do have a skeletal system..... A hydrostatic skeleton or hydroskeleton is a structure found in many cold-blooded organisms and soft-bodied animals consisting of a fluid-filled cavity, the coelom, surrounded by muscles...Some examples are soft bodied animals such as sea anemones and earthworms. Hydrostatic skeletons have a role in the locomotion of echinoderms (starfish, sea urchins), cnidarians (jellyfish),annelids (earthworms), nematodes, and otherinvertebrates. They have some similarities to muscular hydrostats.
No.No, they have two layers of a skin like wall that holds the jell of their body together

∙ 11y agoJellyfish only have two layers of dermis, which are generally are each only one cell thick. The outer layer (epidermis) is always exposed to sea water and the individual cells exchange gases directly. The inner layer (endodermis) uses the same method of gas exchange with individual cells, but the sea water must be brought to it by way of the gastrovascular cavity that runs throughout the individual, even through the middle of each tentacle.
Circulation of seawater (and nutrients) throughout the gastrovascular system is by muscle contraction of the jellyfish bell, and muscular contraction of the tentacles. This eventually exchanges the sea water, but as you can imagine, with only one opening for intake and expulsion, the efficiency of this type of circulatory system is a little lacking. We must consider, however, the advantage that this simple system afforded these organisms over their predecessors.
