#Biodiversity150 number 8 of 150 Bryozoa

8/150: I’m so much more than just moss!

Animalia: Bryozoa: Phylactolaemata: Plumatellida: Fredericellidae

Bryozoa, commonly known as moss animals are a phylum of aquatic invertebrate animals. A single individual, known as a zooid, is typically 0.5 millimeters long. Bryozoans are an immobile species typically residing on hard surfaces such as stone or even your summer cabin’s docks! While these are often thought of as a nuisance, these animals are much more than what they initially seem. Anywhere from a few to millions of zooids come together to form colonies composed of zooids that are responsible for feeding and excretion (autozooids) and non-feeding zooids which are responsible for reproduction and defense of the colony (heterozooids). The feeding zooids contain a lophophore which is a ring of ciliated tentacles around the mouth, used to capture small food particles in the water. Most bryozoans are hermaphroditic, therefore both the ova and sperm are released into the water by the heterozooids for fertilization or others capture sperm via their lophophores to fertilize their ova internally. These plant-looking animals are pretty cool! #Canada150 #Biodiversity150
