Phylum bryozoa

Transcript. So the bryozoans are a group of animals that are a phylum, which means that they are a very large taxonomic group – another phylum that you might know is the molluscs or the echinoderms – so bryozoans are a group as large as that. So just as there are different kinds of molluscs – bivalves and gastropods and chitons – there ...

1 INTRODUCTION. Ctenostome bryozoans are a small and still insufficiently investigated group of the phylum Bryozoa (Schwaha, 2020a).Systematics currently divides ~350 recent described species into approximately 7–8 superfamilies (Jebram, 1973, 1986; Todd, 2000).Classification is almost entirely based on colony and cystid characters.The most important group within Phylum Cnidaria are the corals. Corals are multicellular animals that have a similar life habit to sea anemones. They are anchored to the ocean floor and precipitate a mineral framework around themselves which raises them up off the sea floor to more efficiently collect food. Each coral animal is known as a polyp.

Like other species of bryozoans (also known as Ectoprocta or commonly as moss animals), the individual microscopic aquatic invertebrates (called a zooid) live directly on submerged surfaces in a colony (Ricciardi and Reiswig 1994, Wood 2010).
