In Science lessons we are studying the invertebrates. One of them is the earthworm. They live underground, their body is long and can have 120 or 170 segments, it is soft, wet and slimy.
It is hermaphrodite, it reproduces by eggs. The clitellum stores the reproductive organs. It has got five hearts.
The earthworms eat soil, bacteria and leaves.
There are 3.000 species of earthworms.
We used hand lenses and a binocular microscope to observe and draw earthworms. We put the earthworms in a special box.
Here you have some pictures.
