These are tentacles from a freshwater mollusks know as Bryozoa (Moss animal), which is very similar as soft coral in the sea. However, they are different species. They are aquatic colonial animals as well which grow on the rocks, branches, and leafs under the water. Although the freshwater moss animal is humble, the unique structure and transparent organism make they looks fancy and exotic in the micro-world. Due to unable to photo under the muddy water by MP-E lens, this photo was taken in a Observation box.
