Question

Ectoprocta
A)live in marine and freshwater habitats.
B)typically form colonies.
C)superficially resemble the hydroids of cnidarians.
D)all of these

Accepted Answer

All of these statements are correct. Ectoprocta are aquatic animals that can be found in both marine and freshwater habitats. They typically form colonies, often referred to as "moss animals," that can range in size from a few individuals to thousands. They superficially resemble the hydroids of cnidarians due to their feeding and reproductive structures, but they are actually more closely related to brachiopods and phoronids.
