Lumbricus terrestris
Life and Mathematics!!!. Simple spiral. Through much of Europe, it is the largest naturally occurring species of earthworm, typically reaching 20 - 25 cm in length when extended (though in parts of southern Europe, the native species are much larger). It has an unusual habit of copulating on the surface at night, which makes it more visible than most other earthworms. L. terrestris is an anecic worm. That is, it forms temporary deep burrows and comes to the surface to feed, as opposed to burrowing through the soil for its food as most other earthworms do.
Small brook at the mountains. Pine tree forest
Camera Model: NIKON D300. Exposure Time: 1/250 sec.; f/7.1; ISO Speed Rating: 800. Focal Length: 90.0 mm. Flash fired
