Hydra sp.
I took this picture at home where the Hydra (5 mm) was attached to the glass of my aquarium. The hydra originated from a canal close to the city of Utrecht (The Netherlands)
From Wikipedia: Hydra (pron.: /ˈhaɪdrə/) is a genus of small simple fresh-water animals possessing radial symmetry. Hydra are predatory animals belonging to the phylum Cnidaria and the class Hydrozoa. They can be found in most unpolluted fresh-water ponds, lakes, and streams in the temperate and tropical regions and can be found by gently sweeping a collecting net through weedy areas. They are multicellular organisms which are usually a few millimetres long and are best studied with a microscope. Biologists are especially interested in Hydra due to their regenerative ability; and that they appear not to age or to die of old age.

Thank you for sharing this fascinating spotting Peter, which we are featuring as a fun fact on Facebook today!
The hydra (a tiny relative of the jellyfish) is the only organism scientists have identified that never ages and is biologically immortal. How cool is that!
