As all pioneer species, bryozoans are resilient organisms that are small, simple, and capable of colonising in a hostile environment, altering and creating less stressful conditions for a more complex successional species as in facilitative successions (Bruno et al., 2003).
Bryozoans in the Greenland Sea. 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. Bryozoans may be one of our most overlooked and underappreciated animals. Known as “Moss Animals,” bryozoans are small, simple animals rarely growing more than 1/25 th of an inch in length. However, most bryozoans form colonies that can vary greatly in number, form, and size. Bryozoan biologyFossilized skeleton of Archimedes Bryozoan.
