F) Hypostome, with a nematocyst band (arrowhead). G) Living polyp detached from the host and trying to ingest a portion of the host sponge. H) Capitulum with a central inclusion. I) Polyp with medusa buds organised in clusters. J) Close-up of a polyps with medusa buds clusters arising from the red band area. K) Polyp with medusa buds showing reproductive exhaustion. L) Newly released medusa. M) Desmonemes (d) and small stenoteles (ss) from the polyp. N) Large stenoteles (ls) and small stenoteles (ss) from the polyp. O) Heteroneme from the polyp.
