How do bryozoans move?

Bryozoans primarily remain sessile, meaning they are typically attached to substrates and do not move actively. However, some species can exhibit limited movement through the contraction of their body walls or by the action of cilia on their surfaces, which can help them reposition slightly or escape unfavorable conditions. Additionally, bryozoans can reproduce asexually, forming new colonies that may migrate to new locations over time. Overall, their movement is quite restricted compared to more mobile organisms.
