Bryozoa phylum.

Bryozoa (also known as the Polyzoa, Ectoprocta or commonly as moss animals), are a phylum of aquatic invertebrate animals. Typically about 0.5 millimetres (0.020 in) long, they are filter feeders that sieve food particles out of the water using a retractable lophophore, a 'crown' of tentacles lined with cilia. Most marine species live in tropical waters, but a few occur in oceanic trenches ...Phy­lum Bry­ozoa (or Bry­ozoa ), com­monly known as “moss an­i­mals”, in­cludes over 5,000 cur­rently rec­og­nized species (with over 5,000 ad­di­tional, ex­tinct forms known) of ses­sile, al­most ex­clu­sively colo­nial (only one soli­tary species, Mono­bry­ozoon am­bu­lans, is known), coelo­mate or­gan­isms that su­per­fi­cially re­sem­ble sof...Bryozoans. Introduction. The Bryozoa, also known as Ectoprocta or commonly as moss animals, are a phylum of aquatic invertebrate animals that resemble corals.

Opening its shell like an umbrella, it parachutes down onto a clean kelp blade. Alert for chemical cues, the bryozoan tests the surface, then cements itself to the blade with a sticky glue. The youngster settles in place and changes to its adult form, a captive within its own ...
