These characteristics distinguish them from invertebrates of the clade bilateria, which possess bilateral symmetry in their adult or larval forms.

[3] Zancleids have a complicated taxonomic history, and new species are discovered fairly often due to a better understanding of the range of variation between organisms of this family.

[4] Just like all cnidaria, their tentacles are lined with cnidophores, that house harpoon-like stinging cells called nematocysts.

[3] During the medusa stage, the zancleids feed on small organisms in their proximity, and eggs are released into the water column.

[4] For colonies that prefer to live in association with corals, their presence in the community plays a role in the functionality of their surrounding ecosystem.

Many studies focusing on these organisms examined ones living in the Maldives and the Red Sea, but they have also been identified in the Indian ocean and throughout the Pacific.

In terms of distribution within the benthic environment, bryozoans, the most common host for zancleids, have been seen to express a preference for shaded habitats in the intertidal or infralittoral zones.

Very few studies have focused on compiling the DNA sequences of the different species, and it has also been difficult for scientists to find viable, fertile colonies to conduct their research on.

[3] Many of these species have seen a large reduction in their polyp and medusa stages over the years, which helps support the theories of speciation.
