I think of creating a class of microscopic creatures, called Odelia. I created 3 species: Odelia Lentium: They are herbivorous creatures, and they are slow because throughout evolution they have lost most of their flagella, but they have gained a very resistant cell wall, so they do not need the flagella to escape from predators. Odelia Toxicus: They are carnivorous and feed on Odelia Lentium, using a complex system of toxins that works like this: When they find a Lentium, they emit toxins that slowly destroy their cell wall; then, emit another toxin that enters the holes created by the 1st toxin and accepts to convert everything inside into food for Toxicus; lastly, Lentium collapses and Toxicus absorbs food and leaves in search of another victim. Fortunately for Lentium, toxicus is relatively rare. Odelia Spinam: Carnivores, feed on the two other species. To eat Toxicus, she is eaten by him on purpose and starts to eat like his guts and then pierces Toxicus. For the Lentium, it attacks it with its horn and like the one that comes out of the hole, until there is nothing inside.
