Apr 19, 2020 · Freshwater bryozoans are microscopic aquatic invertebrates that live in colonies that can form into jelly-like clumps, and are often found attached to docks or sticks. Bryozoan colonies can be as big as one foot (30 centimeters) in diameter. The base of each tiny bryozoan is attached to a surface. Bryozoa Bryozoans are colonial animals, meaning that many single zooids are stitched together to make one larger colony, akin to how corals grow. The zooids are soft bodied organisms with tentacles that live inside a cell that is part of the colony’s exoskeleton. The way these cells are arranged depends on the morphotype of the species. Morphotypes Scientists have found bryozoans at depths of up to 8,200 metres but the majority live in much shallower waters.
