Bryozoans, or “moss animals”, are a very diverse phylum of animals including more than 6000 aquatic species. They nearly all form sessile colonies (the “forest”), where each “palm tree” is an individual animal, or zooid.

This one is Membranipora membranacae (Bryozoa / Ectoprocta | Gymnolaemata), an encrusting species typically found on Laminaria seaweeds. Next time you go to the beach, open your eyes, these are very common!

Bryozoans are filter-feeding animals and within the alveoli, each 𝘇𝗼𝗼𝗶𝗱 have its own gut, muscles and nervous system.

The ring of tentacles around the head, or 𝗹𝗼𝗽𝗵𝗼𝗽𝗵𝗼𝗿𝗲, allows them to create an inward water current to bring small particles of food towards their mouth.

What is amazing about bryozoans is that they are very different from other animals, but also incredibly diverse! Some can have a tree-like structure, a hard encrusting exoskeleton like this one, or form a sort of jelly ball…. I can’t wait to show you more species, sometimes there is 3 or 4 different ones in the same sample!
