gonophore
Quick Summary
In zoology, a gonophore is an attached reproductive zooid found in hydroid colonies. These colonies, which are a type of cnidarian, can exhibit polymorphism, meaning different zooids within the colony have specialized functions.12
Specifically, gonozooids are specialized polyps that develop reproductive structures called gonophores. These structures are involved in the sexual reproduction of the organism, typically occurring during the medusa phase of the life cycle. While most cnidarians reproduce sexually, many also have asexual reproduction capabilities.2

…a colony, reproductive individuals called gonophores develop into free-swimming organisms (medusae) that reproduce sexually. Fertilization can be either external or internal; if external, the eggs are shed directly into the water. Internal fertilization results in larvae that swim out of the parent and soon settle on a surface, where they…

cnidarianReproduction and life cyclesGonozooids develop reproductive structures called gonophores. Members of the order Siphonophora, free-floating colonial hydrozoans, display an even greater variety of polymorphs. These include gas-filled floats called pneumatophores, pulsating, locomotory structures called nectophores, and flattened, protective individuals called bracts or phyllozooids.
