Bryzoans
Once bryozoans establish themselves in a body of water, they can be difficult to eradicate. Reduction and control are possible, however. Here are some common treatment options to manage bryozoan infestations: Physical Removal: Scouring and manual scrubbing can remove live colonies from their substrates but is labor intensive and time consuming. So bryozoans are important in a kind of ecosystem way. Experiments have shown that some corals, at least, if you lower the pH in which they live, they thrive just fine. They live, they grow, they reproduce – they just don’t make a skeleton. They turn into a jelly instead of a reef. Whether people want to go snorkel on coral jellies is an ...These small rocky plates contain crinoids, bryzoans, and brachiopods. I had thought of making pendants from these mini plates, but decided against it. These ...
