Hydroidolina Collins 2000

The cnidaria had grown up on the corrosion crust of a steel mesh guard over an on-site preflooder.  Sample froman on-site preflooder on the island of Hiddensee south of the village Kloster. Images were taken using Olympus stereo microscope with Olympus C7070 CCD camera.

A cluster of 'organisms'., but they are joined together through a common stalk that runs over the surface of the Potamogeton stalk.

Single 'organism' with associated stalk.
