9. Polymorphism is a common feature and physiological exchange takes place through the pores of the walls among the colony zooids. 10. Bryozoans are hermaphrodites. 11. Gonoducts are lacking in Phylum Ectoprocta. 12. Sperms are released into the coelom and exit through the pores in the lophophore tentacles. 13.Bryozoa is a phylum of small aquatic invertebrates that filter feed with tentacles lined with cilia. Most species are marine and live in tropical seas, although many are in temperate or cold seas, and some live in brackish or freshwater. Of the ~ 4000 extant species, all but one genus is colonial.

Bryozoan colonies are protected with a covering of organic materials …
The lophophore ( / ˈlɒfəˌfɔːr, ˈloʊfə -/) [1] is a characteristic feeding organ possessed by four major groups of animals: the Brachiopoda, Bryozoa, Hyolitha, and Phoronida, which collectively constitute the protostome group Lophophorata.
