Quick Summary

A gonozooid is a specialized reproductive zooid found in certain colonial animals, such as hydroids and bryozoans. In hydroids, gonozooids are also referred to as gonophores and are responsible for producing medusae, which are the sexual reproductive stage. In bryozoans, gonozooids can function as brood chambers where embryos develop. These reproductive zooids are part of a larger colony, where different zooids have specialized functions, contributing to the overall survival and reproduction of the colony.123
