Discover our dedicated asset collection featuring Anthoathecata, a major order of hydrozoans encompassing calcified reef-building fire corals (Millepora) and intricate solitary and colonial hydroids. Free from rigid protective cups (thecae) around their polyps, Anthoathecata exhibit diverse structural adaptations—from delicate, feather-like solitary plumes swaying in coastal currents to massive, stinging skeletal structures on tropical reef crests. They are essential visual elements for marine invertebrate studies, venom biology research, and ocean conservation media.
