Insects ranging in size from 0.12 mm, smaller than the slipper infusoria, with a nervous system of several thousand neurons, sometimes completely devoid of a nucleus. without the heart and hemolymph, which have not changed in the last 120 million years, found in amber from different countries of the world.

Something I did not see there in the article "without hemolymph". Without heart and blood vessels, it is written.

Well, maybe I got something mixed up. Although it was written that nutrients from the digestive system are distributed through the ogranizm by diffusion... confused.gif

Well, yes, I understood it by diffusion in the hemolymph, but how else?

It can move from cell to cell, as in tardigrades or rotifers. This also happens in nature. They probably have a fat body, as without it. I wonder if there are tracheae? At this size, they also become optional.
