How do boneless organisms move?

They have muscles. Bonless organisims are made of pure muscle. Like a snail and slug, there just a lump of muscle. Thats why salt kills them. Musles is what makes you move. Without our muscles we would just drop to the ground. We wouldnt eat, drink move or see. Musles are what keeps you moving. Lack of exercise means your muscles get weaker so if you just sit around watching tv for most of your time it can somtimes destroy your muscles. That is why exercise is very important.
