Answer 2

I will try to answer your question in detail. Here is a table of the evolution of the skeletal-muscular system (ОДС) in different groups of animals:

| Group | Features of ОДС | | --- | --- | | Simplest | No support structures, movement by pseudopodia, flagella or cilia | | Coelenterates | Skin-muscular sac, movement by contraction of muscle fibers | | Flatworms | Skin-muscular sac, movement by longitudinal, circular and dorso-ventral muscles | | Roundworms | Skin-muscular sac + body cavity filled with fluid, movement by longitudinal muscles | | Annelids | Skin-muscular sac + body cavity filled with fluid, movement by longitudinal and circular muscles | | Mollusks | Skin-muscular sac + shell, movement by muscular foot or jet propulsion in cephalopods | | Arthropods | External skeleton (hard, but not stretchable, requires molting), movement by muscles attached to the external skeleton in bundles | | Lancelet | Internal skeleton (notochord), movement by segmented muscles | | Cartilaginous fishes | Internal skeleton (cartilage), movement by fins and tail | | Bony fishes | Internal skeleton (bone), movement by fins and tail | | Reptiles | Internal skeleton (bone), movement by limbs and tail | | Birds | Internal skeleton (bone), movement by limbs and wings | | Mammals | Internal skeleton (bone), movement by limbs and tail |

You can find more information about the structure and function of the ОДС in different animals in the web search results . I hope this helps.
