Oxygen diffusion?

Since flatworms have a selectively-permeable membrane, they're able to get their oxygen from the atmosphere using diffusion. It's quite a cool feature if you ask me.

Tengen Toppa Gurren Lagann- 26 episodes i think Shakugan no Shana- 2 seasons of a minimum of 24 episodes and a three some time quickly i'm hoping. 0 no Tsukiama- 3 seasons yet in simple terms 13 episodes a season and a forth quickly. it truly is in simple terms 13 episodes yet Angel Beats!, have confidence me it an excellent anime.

Diffusion. That's why they tend to be small and flat - large surface area to volume.
