form either encrusting or bushy-tuftlike lacy colonies on sea weeds,
rocks, and other hard surfaces. The colonies are made up of very
small interconnected individuals (called zooids). The individuals
are bilaterally symmetrical, have organ systems, and lack segmentation.
Bryozoans (along with worm-like phoronids and bivalve-like brachiopods)
are unique among marine invertebrates in having a feeding structure
called a lophophore. It is made up of a set of ciliated tentacles
arranged in a horeshoe-shaped coil and is used to filter food particles
from the water.
