Zanclea Hydroid
Zanclea divergens
Zanclea hydroids of this can be symbiotic with either bryozoans, bivalves, or corals. Symbiotic relationships leads to polymorphism and colony integration with the hosts.
In this hydroid the hydrorhiza is reticulate, growing under the skeleton of the bryozoan host, with discrete clusters of macrobasic euryteles; hydranths sessile, cylindrical; with four short oral capitate tentacles and 25-30 short aboral scattered capitate tentacles; medusa buds on hydrorhiza. Cnido-
me: holotrichous macrobasic euryteles in hydrorhiza and near hypostome, with shaft coiled in a spiral along the short axis for one third of the capsule near the operculum, and with distal part of shaft straight and parallelto main axis of capsule; stenoteles of two sizes in tentacle capitations.
Distribution: Indo-Pacific.
