Polymorphic Zanclea species associated with living scleractinian coral (Pavona divaricata, P. venosa and Psammocora contigua). Hydrorhiza are surrounded by a perisarc, and grow between the coral skeleton and calicoblastic ectoderm. Newly released medusae are almost spherical, with four perradial exumbrellar nematocyst pouches including stenoteles,and two long marginal tentacles with cnidophores. Nematocyst complement consists of two sizes of stenotele and macrobasic euryteles (both in the hydranth and newly released medusa) and apotrichous euryteles in the cnidophores of the tentacles of newly released medusae.
