Jumping worm (Amynthas spp.)Photographs

The following images capture what the jumping worm looks like.

Soil signature
The soil in this plant plug is grainy, dry and almost looks like coffee grounds. Plants may have difficulty growing in this type of soil, which jumping worms create. The unique look and feel of this soil is what we call the jumping worm's "soil signature."
Jumping worms
Jumping worms are smaller and thinner than earthworm species from Europe. Here you can see their glossy-gray color and one, cloudy-white clitellum. The difference in the clitellum is one simple way to know jumping worms from European species of earthworms (learn more below).
Moving jumping worms
Just seconds after these worms were placed close together for a photo opportunity, they started moving away from each other, spreading off the table. This photo shows how they disperse in every direction--and they are quick!
Jumping worm smaller than a pen
Next to a pen, it is easy to see how jumping worms are smaller than your average night-crawler.
Jumping worm
This is a beauty! Notice the grainy, dry soil this worm is with and the cloudy-white clitellum (lighter colored band) on its body. A jumping worm's clitellum goes completely around its body and is smooth to the body, not raised.
Jumping worm in soil
This worm is sitting in soil that has the jumping worm "soil signature." The soil is dry, grainy and made up of worm poop (castings). It is not a healthy soil for many plants.
Jumping worm close-up view
Here it is easy to see that the clitellum (lighter colored band) does not rise up above the rest of the jumping worm's body. It is smooth against the body, unlike European species of earthworms.
Jumping worm clitellum
The clitellum is the lighter colored band around the body of the worm. Jumping worm clitellums are cloudy-white, go completely around the worm's body and are smooth to the touch, not raised above the rest of the body.
