Klaas Gerdes, biologist at the institute „Senckenberg at the Sea“ in Wilhelmshaven (DZMB): These are our sieves with a mesh size of 1 cm down to 40 µm. We use them mostly for meiofauna, very small animals invisible to the eye that live in sediments or on the surface of rocks. With the help of the sieves, we wash them off and collect them for further examination
