Tardigrades are their own life-form. You can see them with your naked eye, barely, but you'd need an electron microscope to bring out this kind of detail. They live in pond water and on lichen. They can survive in space, at near absolute zero, at temperatures above boiling, at the bottom of the ocean. Dry them out for 10 years, just add water and they're good as new. 8 legs. Claws. What's not to like?! And if you paint them, no one will ever say "They don't look like that."
