What is the significance of flatworms being flat?

Answers

Flatworms (Platyhelminthes) are phylum of unsegmented, soft, flat invertebrates.

Flatworms have no body cavity which is why they are flat. The advantage of a flat body is facilitated respiration and circulation. Flatworms do not have respiration and circulation system. But, oxygen diffuses across the skin and reach all parts of the body thanks to a flattened shape. Also, it is easy to hide from predators because they can get almost everywhere thanks to the body shape.
