In which in the human body they carry Oxygen through-out the body. Erycoon shows this by carrying berries or other small items in it's tail "pouch".

Both have simplistic designs at first glance but ingame when you use them and by looking up facts about them on the wiki, you can find that they are actually quite interesting. Things like the Dex Entrys and Lore can give exciting incite on their designs. And movesets and abilities can add to that. Like how Erycoon receives quite a few supporting moves as with how red blood cells support the body. And Leukoon receives some interesting fighting moves like how white blood cells attack invaders in the body.
