Cheilostome bryozoans have a complex life cycle with distinct asexual and sexual modes of reproduction (Taylor, 2020; McKinney and Jackson, 1991). Asexual reproduction allows for a single colony to grow larger by increasing the number of zooids in the colony. The sexual stage of the cheilostome bryozoan life cycle leads to the …
